Title: Speed signal generator
Inventor: SHIMOO SHIGERU
IPC: G01P3/48
Filed: 1978-06-09
Abstract: PURPOSE: To generate highly accurate signals in high responsibility with the use of a simple circuit by connecting a frequency divider and a delay element between a shift register circuit and a position pulse counter.  
     CONSTITUTION: A frequency divider 14 and a delay element 17 are connected between a shift register circuit 15, which is made respective of clock signals 103 from a clock generating circuit 13 together with a pulse latch circuit 12, and a position pulse counter 11 which is receptive of incremental position pulses 101 and 102 together with a pulse latch circuit 12. As a result, the pulse count signals 109 of the position pulse counter 11 are loaded on a speed counter 16 in response to the sample lock signals 104 of the frequency divider 14 so that the speed counter 16 is initialized for each period of the sample clock signals 104. At the same time, the sample clock signals 104 are delayed by a delay element 104 such a time as is required for the loading of the speed counter 16. As a result, the pulse count signals 109 become the count values of the position pulses 101 and 102 which are fed during one period of the clock signals 104 thereby to attain the desired object.

Title: Semiconductor device
Inventor: TAKANO SHINJI
IPC: H01S5/00
Filed: 1986-03-27
Abstract: PURPOSE:To obtain a high resistivity and ecorver damages of crystal, by a method wherein the ion implantation of InP or InGaAsP is performed on an InP substrate so as to overlap and annealing is performed within 10 min at a temperature equal to or lower than 400 deg.C. CONSTITUTION:Protons of 9.1X10<15>/cm<3> in total amount are implanted in multiple mode into p-InP in the manner in which acceleration energy and implantation quantity are changed in order, and carrier density is made nearly uniform up to the depth of 1.5mm. When a thermal treatment within 10 min at temperature equal to or lower than 400 deg.C is performed, a region (high resistive layer) is obtained whose carrier density is lower as compared with the case where only the proton infection is performed. In the case where the treatment temperature is equal to or lower than 300 deg.C, the carrier density increases, and the effect does not appear for a treatment time equal to or less than 1 min. Resistivity can be controlled in a wide range by changing the amount of infection. Deterioration of optical characteristies caused by crystal defects generates, but it is recovered by the thermal treatment. This method can also be applied to n-InP and InGaAsP, and He, Ne, etc. are used for the implantation of ions.

Title: Backup system of oscillating circuit
Inventor: EBIHARA HEIHACHIROU
IPC: G04G19/08
Filed: 1979-06-08
Abstract: PURPOSE:To prevent an oscillating circuit in heavy load drive from stopping without reference to input capacity by maintaining the operation of the oscillating circuit by increasing the number of stages of amplifiers when an electric power voltage lowers. CONSTITUTION:When control signal CL increases in potential, electronic switches 19 and 20 are OFF and ON respectively and inverters 17 and 18 are built in the oscillating circuit composed of crystal vibrator 13, inverter 8, etc. Therefore, even if the value of input capacity 11 is large and the input amplitude of inverter 8 is small so that a sufficient current can not be led out from its output terminal, the output voltage of inverter 8 is amplituded more than the input amplitude and further amplified by inverter 17, thereby applying inverter 18 at its input terminal with a sufficiently-large signal. Consequently, the sufficiently-large current can be led out from the output terminal 18 to supply vibrator 13 with the enough driving current to maintain vibrations of vibrator 13. Then, the oscillating circuit can securely be prevented from stopping in heavy load drive.
