摘要： In an output buffer of a DRAM, a level shifter outputs a step-up potential responsively when an internal data signal goes low or a test mode signature goes high. An N-channel MOS transistor is rendered conductive in response to the step-up potential from the level shifter, and sets a data input terminal to a power supply potential. The internal data signal and the test mode signature share the level shifter and the N-channel MOS transistor, and hence the layout area can be small and a high-level test mode signature can be output.
摘要翻译：在DRAM的输出缓冲器中，当内部数据信号变低或测试模式签名变高时，电平移位器响应地输出升压电位。 N沟道MOS晶体管响应于电平移位器的升压电位而导通，并将数据输入端设置为电源电位。内部数据信号和测试模式签名共享电平移位器和N沟道MOS晶体管，因此布局面积可以较小，并且可以输出高级测试模式签名。

摘要： A resin chain is provided which includes a reinforcing plate and a resin portion having a contact surface therebetween such that it is difficult to separate the reinforcing plate from the resin portion at the contact surface. The resin chain includes outer plates with pins fitted therein and inner plates with bushings fitted therein. The outer plates and the inner plates are connected to each other in an alternate manner. A first reinforcing plate is a constituent of each outer plate. The first reinforcing plate has a pair of cylindrical front and rear boss portions with pins fitted therein and a flange portion which rises radially from the outer peripheries of the boss portions to connect the paired front and rear boss portions to each other. A second reinforcing plate is a constituent of each inner plate. The second reinforcing plate has a pair of cylindrical front and rear boss portions with bushings fitted therein and a flange portion which rises radially from the outer peripheries of the boss portion to connect the paired front and rear boss portions to each other. Resin is molded along the surfaces of the flange portions front the outer peripheries of the cylindrical boss portions so as to fill up recesses formed between the boss portions and the flange portions. The outer and inner plates are also fabricated in this way.

摘要： A chain capable of diminishing noise and wear occurring at the time of engagement of the chain with a sprocket is provided. At least a portion of an inner surface of each inner plate, which comes into opposition to a side face of a tooth top of the sprocket at the time of engagement of the chain with the sprocket, is chamfered in a shape conforming to the contour of a side tooth form of the sprocket tooth top. Since a chamfered portion of an inner surface of each inner plate has a shape conforming to the contour of a side tooth form of a sprocket tooth top, the chamfered portion and the sprocket tooth top come into contact with each other smoothly in a state of face-to-face contact, so that the level of noise generated upon engagement of the chain with the sprocket can be reduced and it is possible to suppress the wear of the inner surface of the inner plate and that of the tooth top of the sprocket.

摘要： A regenerative braking system for a car in which when a hydraulic circuit is not operated, effective maximum displacement controlling current and minimum displacement controlling current for a pump/motor in the hydraulic circuit are studied on the basis of a variation of the sensed displacement angle when the maximum permissible current and the minimum operating current previously given to a displacement angle controlling electromagnetic proportional control valve are respectively decreased and increased stepwise. A displacement controlling current per a unit capacity for the control valve is determined.

摘要： Parity is generated in accordance with digital data. The parity is added to the digital data to produce a coded signal. The coded signal is recorded. The recorded signal is reproduced. The reproduced signal is decoded and code word errors are corrected to reproduce the digital data. The number of symbols of the digital data equals m-(2n+1). The number of symbols of the parity equals 2n+1. Each of the symbols has l bits. The characters m and n denote natural numbers. The character l denotes a natural number equal to or greater than 2. Coding and decoding are performed by use of new-type Reed-Solomon code.
