IPC: H01L23/48
Filed: 1983-03-29
Abstract: PURPOSE:To reduce the amount of an intermetallic compound produced during joining with Sn solder and to increase the sticking strength by adding prescribed percentages of Ni and Zn to Cu. CONSTITUTION:The titled electronic parts are made of a Cu alloy contg. 1- 5wt% Ni and 0.1-3wt% Zn while satisfying an equation Zn(%)>=1/20Ni(%). Fe may be substituted for part of said Ni.

Filed: 1986-03-11
Abstract: PURPOSE:To decrease the occurrence of a noise due to a step-shaped step by assigning a difference with a previous value to respective sampling data in accordance with a ratio to the sampling period of sampling data. CONSTITUTION:A ratio setting circuit 5 sets a ratio of an optional period shorter than a sampling period and a sampling period as a prescribed ratio, sets a ratio of the period by a factor of the integer of the sampling period and the sampling period, or sets the ratio of the phase difference between the period, which is the same as the sampling period and in which the phase is dislocated, and the sampling period and the sampling period. An envelope generating device is D/A-converted after step-shaped sampling data are read from a ROM1 for a sampling period, the product of the output of a difference detecting circuit 4 and the output of a ratio setting circuit 5 is assigned and thus, the width of the step-shaped step of the sampling data is made narrower. For such a reason, the output of a D/A converter 8 comes to be a smooth waveform.

Title: Light receiving circuit
Inventor: KUWANA ISAMU
IPC: H04B10/69
Filed: 1985-03-15
Abstract: PURPOSE:To expand a receiving dynamic range by usually receiving a receiving light by using two APDs, adding output signals of both the APDs and inputting them to an AGC amplifying circuit, and eliminating one of both the APD and inputting only the other output signal to the AGC amplifying circuit, when the receiving light exceeds some standard. CONSTITUTION:In case the level of a receiving light is usual, both of two APDs 7a, 7b receive the receiving light, add electric signals being the respective outputs and apply them to inputs of an AGC amplifying circuit 2. When the level of the receiving light goes to high, and as a result, the level of an output DC signal of a P-P detecting circuit 3, namely, the control voltage of an AGC amplifying circuit 4 exceeds some reference value V0, a comparing circuit 5 operates and turns a transistor 6 to an on-state. Therefore, in the APD 7a and the APD 7b which are operated, the electric signal of an output of the APD 7b is short-circuited so that it does not go into an input of the AGC amplifying circuit 2. As a result, an input level decreases (about 6db), and the upper limit of the control limit is expanded in proportion to said decrease.

Title: Write protection processing method
Inventor: KIKUCHI NOBUYUKI
IPC: G06F21/80
Filed: 1990-03-02
Abstract: PURPOSE:To prevent the write of the wrong data into a disk by inhibiting the immediate execution of the write protection processing despite the turn-on of a write protection setting switch and carrying out the write protection processing at the starting time point for execution of a write instruction or at a sector boundary, i.e., at a section where the data normalcy is assured. CONSTITUTION:A control means 4 writes continuously the data received from a host device 1 into a recording medium 5 up to a section where the normalcy is assured for the data to be written into the medium 5. At the same time, the means 4 checks the presence or absence of the write inhibiting instruction received from an instruction means 3 every time the data are written into medium 5. When the means 3 instructs the write inhibition, the write inhibition processing is carried out to discontinue the write of the data received from the device 1. Meanwhile the following data are continuously written up to a section where the data normalcy is assured when the means 3 does no instruct the write inhibition. Thus the data having their assured normalcy are always recorded in the medium 5. As a result, the wrong data are never written into the medium 5 even though the means 3 instructs the write inhibition of data.
