摘要： A host device (32) generates LD driving information for the full range of desired operating temperatures by mathematical approximation from the LD driving information threshold current Ith and modulated current Imod at two to three temperature points supplied from the LD manufacturer, thereafter actually operates a transmitter (1T) at a room temperature and acquires the then LD driving information. Then the device (32) compares the acquired actual driving information with the driving information obtained by approximate expressions at the same temperature point and obtains drive control data by correcting the driving information in the full temperature range obtained by the approximate expressions based on the difference between both information. The data calculated using the approximation expressions are corrected by using correction coefficients acquired based on the driving current measured at a specific temperature. Therefore, it is unnecessary to measure the driving current in the full range of temperature, and driving control data which are the most suitable for the actual use of the optical transmitter, namely, which conforms to the characteristics of the optical transmitter and laser diode can be obtained efficiently.

摘要： Let the received level of reference light of an optical transmission module (1, 1A) included in an optical transmission system be m, the transmitted level thereof be n, and the attenuation factor of the light signal fed from a subscriber line station unit (SLT) and received by a subscriber line network unit (ONU) (#1) be alpha (= received level/n). Then the optical output level of the subscriber line network unit (ONU) (#1) is mx1/ alpha . Thus the ONU (#1) outputs the light signal of an output level which is the product of the input and the inverse number of the attenuation factor to the SLT, and hence the SLT receives the signal at the reference light received level m from any of the ONUs. Therefore, the gain control of the circuit which amplifies the received levels of a plurality of kinds of light signals having suffered different line losses and the resetting of the threshold voltage for detecting the logical value of the received signal are simplified or the circuits for controlling the gain and resetting the threshold voltage are eliminated.

摘要： In an optical transmission system using a point-multipoint transmission system, a controller for controlling the drive of an LD is provided in an optical transmitter installed in a subscriber's house; by means of the controller, the LD of the optical transmitter is usually set in a zero-bias state or in a reversely biased state; an on-hook signal sent from a telephone set or a computer connected to the optical transmitter when the telephone set or the computer is in an on-hook operation by the user is detected; and a forward bias current is made to flow through the LD based on the on-hook signal. Since the LD of the optical transmitter installed in the subscriber's house is set in a reversely biased or in a zero-bias state when it is in an on-hook operation, the spontaneous emission components disappear from the LD of the optical transmitter. In addition, since a modulated current based on the data signal to be transmitted while the forward bias current flows through the LD is given to the LD, optical signals are outputted from the LD without light emission delay. Moreover, since the transmission and reception of the optical signals are made through the same optical fiber and the optical signals are transmitted by adjusting the output level by the amount corresponding to the attenuation of received signals caused by transmission loss, the received levels of optical signals from each subscriber's house at the subscriber's terminal station are uniform.

摘要： An optical transmission module (1) is provided with a light transmitting section (10, 11 and 12) which outputs inputted electric signals after converting the electric signals into optical signals, a light receiving section (13, 14 and 15) which outputs inputted optical signals after converting the optical signals into electric signals, and control means (17) which controls the light transmitting and receiving sections by selecting a synchronous transfer mode or a burst transfer mode of the sections in accordance with the case that the electric signals are synchronously transferred together with synchronous clock signals and data signals or the case that the electric signals are burst-transferred excepting the synchronous clock signal. The control means (17) receives control information specifying the transfer mode, the synchronous transfer mode or burst transfer mode, from the light receiving section and holds the control information in an electrically erasable programmable flash memory (173). A CPU (170) controls the light transmitting and receiving sections in the synchronous or burst transfer mode based on the control information. Therefore, the transmission mode of an optical transmission system to an electric signal system can be easily changed through such a simple operation as the rewrite of the control information.

摘要： A microcomputer (5) constituted in an integrated circuit including an electrically erasable programmable nonvolatile memory (56) and a central processing unit (51) is adopted for controlling a disk drive (2). The memory (56) stores an application program, such as a recorded information reproduction control program in an application program area (561) and a reboot program which is utilized to update the application program in a reboot program area (560). The processor (51) rewrites all or part of the application program by executing the reboot program according to an application program rewriting command supplied from the outisde. Therefore, all or part of the application program stored in the memory (56) can be rewritten even after the microcomputer (5) is mounted on a disk drive. Since the reboot program area is not rewritten, the reprogram of the application program area is restarted immediately after the reboot program is executed again even when the reprogramming of the nonvolatile memory is interrupted due to abnormality.

摘要： A method for manufacturing a resin-encapsulated semiconductor device in which a die pad has an area smaller than that of a semiconductor chip mounted on the major surface of the die pad and the semiconductor chip and the die pad are encapsulated in a molded resin body. The semiconductor chip and the die pad are so arranged in the cavity of a mold that the clearance between the rear surface of the die pad and the opposed internal surface of the cavity is narrower than the clearance between the major surface of the semiconductor chip and the opposed internal surface of the cavity by the distance corresponding to the thickness of the die pad. A resin body is molded by simultaneously injecting the resin into the cavity through center gates. Thus the semiconductor chip is not moved upward by the resin injected into the space on the rear side of the chip. Therefore, the yield of the resin-encapsulated semiconductor device is high because such a defect that the semiconductor chip, bonding wires, etc., are exposed from the molded resin body, is prevented.
