Patent JP-H0327608-A (JP)
Title: Optical agc circuit
Inventor: TAKEYARI RIYOUJI
IPC: H04B10/80
Filed: 1989-06-26
Abstract: PURPOSE:To obtain a circuit applying AGC operation by keeping a multiple factor independently of an APD current at small reception power constant and making the APD current constant at large reception power. CONSTITUTION:A FET bias circuit 2 shows a resistance characteristic with unsaturation voltage when a drain-source voltage of a FET is 0.5V or below and shows a constant current characteristic with the saturation when the voltage is 1V or over. Then the current of the circuit 2 is set to obtain a maximum operating current of the APD 1. When reception power is small, since the APD voltage and the terminal voltage at the circuit 2 are nearly made constant, the multiple factor of the APD 1 is nearly constant, the gain of an AGC amplifier 7 has a constant characteristic to attain the AGC operation. The APD current is made constant by the circuit 2 at a region where the reception power is large. Thus, the APD multiple factor is decreased inversely proportional to the reception power to attain the AGC operation.

Abstract: PURPOSE:To execute easily and exactly the selection of a disk and setting of a reproducing start by a driver by writing and storing a discriminating data and a reproducing halt address of a digital audio disk ejected on the way of reproducing in a memory, so as to cope with a reproducing restart. CONSTITUTION:When a stop button 22b of an operating panel 10, the pause operation is set, the reproducing operation is stopped, and also discriminating information and a reproducing halt address of a digital audio disk are written in an RAM of a controlling circuit 14. When the button 22b is operated in this pause state, the disk is ejected. Subsequently, when the disk is inserted into a player and a continue button 22c is operated, the discriminating information of the RAM32 is referred to, and in case the result does not coincide with read-out discriminating information from the disk, it is alarmed and transferred audibly. On the other hand, in case they coincide with each other, a reproducing restartposition of the disk is set automatically based on the storage contents of the RAM32. According to such constitution, the selection of the disk and setting of reproducing start of the disk are executed easily and exactly.

Title: Ignition device for internal combustion engine
Inventor: SAGA TOSHIHIRO
IPC: F02P5/155
Filed: 1986-07-09
Abstract: PURPOSE:To make a timing advance inhibiting circuit unnecessary to be installed as voltage at the other end is not dropped more than the reference voltage point to a second angular position signal, by inputting the other end of a condenser, where a DC power source is connected to its one end, into a comparing device. CONSTITUTION:One end of an operating condenser 108 of an ignition timing control circuit 13 is connected to a DC power source +V, and the other end is inputted into a comparing device 800 and compared with reference voltage VS. And, at the time of starting, a switch 700 is closed by a first angular position signal out of a terminal A via a comparator 200 and an OR circuit 910, and the operating condenser 108 is charged by constant voltage +V, and when it is reached to the reference voltage VS, an ignition signal G is outputted out of the comparing device 800. Therefore, even if the other end voltage of the condenser 108 is dropped, this other end voltage is in no case dropped more than the reference voltage prior to a second angular position signal, so that a timing advance operational signal will not occur. Thus, a timing advance inhibiting circuit which has so far been unrequired becomes unnecessary, thus the number of part items is reducible.

Title: Underwater pump with sand removing device
Inventor: NAKASUJI AKIRA
IPC: F04D7/04
Filed: 1979-12-14
Abstract: PURPOSE: To enable removal of fine sand, thereby preventing suction of sand into the impeller, by a method wherein de Laval type, centrifugal separator rotated by  the pump driving shaft in the water stream is provided on the intake side of the  pump.  
     CONSTITUTION: Between the underwater motor 10 and the impeller 14, a de Laval type centrifugal separator 28, consisting of several numbers of thin, umbrella shaped disk superposed at the predetermined intervals and rotating incorporated with the pump driving shaft 12, is provided in the water passage on the intake side of the pump. With this constitution, when water containing sand is about passing through the layers of the disk of centrifugal separator 28 from outside to inside, water and sand revolve around the driving shaft 12 because the intervals among disks in layers are made small, and with the centrifugal function, the sand of large specific gravity is exhausted, but only water can passes through the water passage 30 which is in the inside circumferencial part of the separator. Accordingly, locking in the disks in layers of the centrifugal separator 28 by sand can be prevented, as well as fine sand can be discharged.

Title: Fault detection system of decentralized control type switching system
Inventor: KATOU MITSUO
IPC: H04Q3/545
Filed: 1978-12-25
Abstract: PURPOSE:To make it possible to grasp precisely a fault of a system and its activity state by sending a call connection request by installing in a specific decentralized processor a testing equipment equipped with a terminal function as a testing artificial terminal. CONSTITUTION:In every constant period, testing equipment TSE202 sends a connection request to testing procedure unit 208 installed in each decentralized processor 203 to test units 203 constituting the system. Namely, if each decentralized processor where the connection request has been sent would not be connected well as many times as fixed within a certain time, TSE202 judges that some fault is occurring, thereby analyzing the result. Therefore, TSE202 can judge a system fault when requested connections to all decentralized processors can not be made well or a decentralized-processor fault in other cases. Consequently, the falut of the system and the activity state of each unit can be grasped with precision.
