Title: Recovery relay circuit for dial pulse
Inventor: KIKUCHI TETSUYA
IPC: H04M1/00
Filed: 1987-12-23
Abstract: PURPOSE:To improve the reliability and to attain miniaturization by using a field effect transistor(TR) in place of a relay in a dial pulse recovery relay circuit of a 4-wire/2-wire converter. CONSTITUTION:When an off-hook signal is supplied and a dial pulse is outputted from a termination circuit 10, a TR 9 replies the dial pulse to turn on/off the loop of a 2-wire transmission line thereby relaying a dial pulse. Then a capacitor 7 is charged via a photocoupler 2 during the dial pulse relaying and the field effect TR 3 is conductive. Thus, the impedance viewed from are exchange is lowered and the distortion of the dial pulse due to the impedance of the termination circuit is prevented. Moreover, since a bias voltage is supplied to the TR 3 via a Zener diode 5 during talking, the impedance is high in terms of AC and no effect is given to a voice signal.

Title: Memory protecting device
Inventor: YAMADA SHIGEKI
IPC: G06F12/14
Filed: 1991-11-12
Abstract: PURPOSE:To form a system of the high reliability with no deterioration of the system performance by storing the protection key information in a memory protection information storage means and checking the errors in parallel with a memory access. CONSTITUTION:If an access is given by mistake to an area of a memory pool 18 due to the runaway of a program, etc., the discordance is detected as long as an access is given to a memory block that is not registered in the protection key registers 20-1...20-k. The discordance is also detected even if the coincidence is secured between the area of the pool, IR end either one of higher order addresses of the memory blocks which are already registered in the registers 20-1...20-k since the process number under execution is different from a registered process number. When the discordance is detected in a state register 24, an access control part 16 immediately stops the accesses given to the pool 18 in parallel to each other. Then the part 16 informs a processor 11 of the occurrence of an exceptional event. Thus the memory access can be protected.

Title: Crystal growth of compound semiconductor
Inventor: SAKUMA YOSHIKI
IPC: H01L21/203
Filed: 1988-12-20
Abstract: PURPOSE:To grow the crystal of a compound semiconductor wherein In characterized by excellent surface morphology and excellent uniformity in film thickness is a constituent element by supplying raw material including In for each period by the amount equal to or less than that required for depositing In on a substrate by one atom layer. CONSTITUTION:At first In atmos which are supplied at the first period are all attached on a substrate 1. A region where the In atoms are not attached still remains on the surface. P atoms which are subsequently supplied are attached to the In atoms, and one layer of the InP molecule layer is formed. The excessive P atoms which cannot be attached to the In atoms are unstable and their attaching force to the substrate is weak. Therefore, the P atoms are discharged to the outside. In the second cycle, In which is supplied thereon is attached to a remaining region on the substrate where the InP molecule layer is not formed yet. At this time, the excessive In atoms are attached to the P atoms, but the opportunity that the In atoms are continuously overlapped is less. The P atoms which are continuously supplied are attached to the In atoms. The excessive P atoms are discharged to the outside. When the supplying amount of the In per one period is made to be the amount or less required for forming one atom layer, the overlapped growing of the In atoms can be prevented.

Filed: 1989-12-15
Abstract: PURPOSE:To output a fast light pulse string without receiving the limitation of the band of an electrical system and to easily perform the control of a pulse gap by controlling the switching of a reflecting state and a transmitting state for signal light with control light fed back via a light feedback part. CONSTITUTION:Input signal light Pin is made incident on the prescribed position of a nonlinear etalon NE from a prescribed direction with a signal light input part SI. Since no control light Pc is made incident on the etalon NE at that time(feedback light quantity=0), high reflectance exists on the etalon NE, and most of incident signal light Pin is reflected on the NE. Reflected signal light Pr is made incident on the light feedback part RT, and is delayed for prescribed time td by being propagated on a prescribed optical path OW, and is fed back to a control light input part CI as the control light Pc, and the control light Pc is made incident on the prescribed position of the etalon NE. Thereby, the reflectance of the NE is decreased, and the signal light Pin transmits the NE, and transmission light Pt is outputted as the output light Pout of the optical oscillator. The reflectance of the NE is increased after the time td by decreasing the reflectance of the NE, then, a state is returned to an initial state, and oscillation is performed by repeating such operation.
