摘要： PURPOSE:To easily perform a program searching by making it possible to record an index signal also in case of recording from a recording pause at the recording of only voice. CONSTITUTION:A sound signal and a video signal are recorded from external signal input terminals 3a, 3b in a magnetic tape through a sound signal recording circuit 5 and a video signal recording circuit 6. Only when a synchronizing signal is included in the video signal, a video signal detecting circuit 10 outputs a logic low level output 10a. Since the output 10a is in the low level when the recording signal is the video signal including the synchronizing signal in said constitution, an index signal recording circuit 13 is not driven even if a high level signal is outputted from a system control circuit 15 at the release of the recording pause. Since the output 10a is in the high level at the recording of only the sound signal, an index signal is recorded by a signal 15a also at the release of the recording pause. In case of recording from a stop mode, an output 15b is used to actuate the circuit 13.

摘要： PURPOSE:To cool a plurality of LSI chips with high efficiency, and to facilitate assembly without applying external force to each LSI chip by executing machining containing pressure joining treatment to a ring-shaped sheet metal in a bellows and manufacturing the joining bellows. CONSTITUTION:Bellows rings 4, outer-circumferential joining rings 3 and inner- circumferential joining rings 2 are patterned and machined through an etching method from a metal sheet 1 in Ni, etc. having high corrosion resistance as a blank for a bellows. These rings are brought to the state in which they are fixed to frames 12 by bridges 11 so as not to disperse at that time. Films are formed onto several joining ring 2 and 3 in thickness of several mum or less on both surfaces from an alloy. Sections with which the bellows rings are not joined are coated with minerals as joining preventive films 7, and the bellows parts 2, 3 and 4 are laminated in conformity with the number of crests as required. The bridges 11 and the frame 12 attached to the bellows parts are cut and removed as required after joining, and the bellows are stretched and molded.

CONSTITUTION:A bonding metal film 2 is formed on one flat surface of a heat conducting material. Then, by not etching, cooling path grooves 3 are formed in the heat conducting material 1, on which the bonding metal film 2 is formed. The heat conducting materials 1 and 1', in which the cooling path grooves are formed, are made to face and bonded. Thus cooling path 4 are provided. Then, the heat conducting material 1 having the cooling paths 4 in the inside is coated by a macromolecular material 5. Thus a cooling structure body is manufactured. Heat yielded during the operation of a semiconductor element is efficiently removed from the heat transfer surface of the cooling structure body. This body is effective in high density mounting of electronic parts, and in the implementations of the compact devices and light weight.

摘要： PURPOSE:To obtain a joint part in which a joint failure and a void are scarcely generated, by forming directly a eutectic compound layer of a specified thickness in advance on a contact surface of two metallic surfaces. CONSTITUTION:When executing a diffused junction by making joint surfaces of two metallic members contact, a part which becomes the joint surface is processed by an Ar ion beam, and cleaned, and thereafter, a eutectic compound layer of 0.01-5mum thickness is formed. Subsequently, it is opposed to the other member to be joined, and its diffused junction is executed in a vacuum or inert atmosphere. In this regard, the eutectic compound thin film alloy layer is formed by using Cu as its main component, also adding Ti or Mn, Ag and Si, and executing a spatter vapor-deposition, and a molting start temperature of the eutectic compound alloy layer is adjusted so as to become lower than that of the material to be joined.

摘要： PURPOSE:To obtain an inexpensive printer control system by counting an FG pulse of a drive motor and deciding a print position of a dot string. CONSTITUTION:A frequency generator FG8 generates a signal proportional to the rotation of a shaft for constant speed control. A print start command signal generator 9 can be a device representing the arrival of the same relative position at all times when recording paper is turned once. A frequency divider 11 is a counter for the FG pulse, a control circuit 12 energizes a heat sensing head 13 with time or power in response to the picture information at the place based on the rising time of a signal of a counter 11. Thus, the FG of the constant speed motor and the drum turning position sensor are used in common and the titled system is advantageous in cost.

摘要： PURPOSE:To form uniformly a low melting point alloy layer for diffusion joining on joint surface by providing a film for preventing the formation of the low melting point alloy layer on the surface of a material to be joined except its joint surface then forming the low melting point alloy layer on the joint surface and removing the above-mentioned preventing film by an etching treatment. CONSTITUTION:A film 3 for preventing the formation of a low melting point alloy is formed on the part of a material to be joined 1 except its joint surface 2, then a low melting point alloy layer 4 is formed by a packing method on the surface 2. An etching preventive film 5 is formed on the surface of said layer 4 and is subjected to an etching treatment to remove the film 3. The film 5 is then removed by using a solvent so that the low melting point alloy layer for diffusion joining is formed only on the surface 2. The low melting point alloy layer is easily formed on the joint surface having an intricate shape by the above-mentioned method.

摘要： PURPOSE:To obtain a circuit system which is suited to an AM receiver, etc. of a car without extreme deterioration of sound quality, by connecting smoothly as much as possible the front and back sides of a part where a signal is omitted due to a noise. CONSTITUTION:A signal waveform (e) containing impulsive noise is made to pass through a switch circuit including a circuit that has a fixed delay time (a fixed level required only at a desired frequency band) and holds a signal at a signal level obtained immediately before cut-off and during a noise detecting period. Thus a signal waveform (d) shown by a dotted line is obtained. The level at a point R is equal to the level at a point Q of the waveform (e) for the waveform (d) in which the cut-off time (t2-t2) is identical with a delay time (gamma). Then a current which is proportional to a level difference (Q-P) obtained immediately before the cut-off of the waveforms (e) and (d) is supplied to the above-mentioned holding circuit during a cut-off period. As a result, it is possible to turn the waveform (d) into a waveform of a solid line.
