Title: Recording and reproducing device for optical disk
Inventor: OKAO KEIICHI
IPC: G11B7/00
Filed: 1989-09-28
Abstract: PURPOSE:To detect a recording information with a high S/N ratio and yet with high efficiency by detecting the information recorded on the multilayer optical recording medium formed by the superposition of plural optical recording layers with the proper combination of a transmitted light and reflected light. CONSTITUTION:The informations recorded on the optical recording layers 6-9 of a multilayer optical recording medium 10 are detected with the reflection light 11a and transmitted light 12a emitted from a recording face respectively at the front and back sides of the multilayer optical recording medium 10 formed by the superposition in order respectively of plural optical recording layers 6-9. The noise in a reproduced signal is then restrained to the minimum because of the both signal lights obtained at this time being processed so that the recording information has a high S/N ratio and the signal of a high S/N ratio is obtd. Thus the S/N ratio and the efficiency of the reproduced signal of the information recording face are not only reduced but also the recording capacity per sheet of the optical recording medium 10 can be increased.

Abstract: PROBLEM TO BE SOLVED: To use a FAX MODEM in-loop speech circuit in common for a speech circuit for telephone set without needing the speech circuit exclusive for a telephone set by providing a 2-4 wire conversion means, a MODEM and a changeover means that selects alternatively a handset between a transformer and the MODEM. SOLUTION: In the case of receiving a FAX signal in the automatic reception mode, a FAX engine 14 receiving a detection signal of the incoming call by a detector 21 gives an XCML signal to a changeover switch 25 to be thrown to the positon of M thereby placing a transformer 10 and a primary telephone line 8 into a closed loop. In this case, an analog switch 27 is thrown to the position of a contact (f) to connect lines 1, 2 to a MODEM of the FAX engine 14 via the transformer 10 to receive the FAX signal.  In the case of the manual reception mode, when the detector 21 detects the incoming call and a handset 19 is hooked off, the FAX engine 14 gives the XCML signal to the changeover switch 25 to be thrown to the position of M thereby placing the transformer 10 and the primary telephone line 8 into a closed loop, and gives a switching signal 31 to the analog switch 27 to be thrown to the position of a telephone side contact (t) so as to allow the handset 19 to speak.

Title: Filter device
Inventor: KIKUCHI SHOGO
IPC: B01D37/04
Filed: 1987-10-05
Abstract: PURPOSE:To backwash a filter layer in a short time by allowing washing water in a water storage tank to flow down to a filter tank buried in the submarine stratum and diffusing suspended solid into raw water and carrying off it. CONSTITUTION:Seawater 1 is sucked from an intake pipe 12 through a filter medium 6 and sent through a feed pipe 16 from a pump 11. A filter tank 5 is buried in the submarine stratum 3 and the filter face 7 thereof is exposed into seawater 1. A water storage tank 9 is provided on the ground 8 and one part of filtrate is replenished via a water supply pipe 17. When the resistance of the filter tank 5 is made high and washing is necessitated, water storaged in the tank 9 is allowed to flow down only by gravity. Thereby the filter face 7 of the filter tank 5 is disturbed and destroyed and thereby suspended solid in the filter tank 5 is immediately diffused into the seawater 1 and carried off.

Title: Automatic centrifugal clutch for car
Inventor: SOU KOUKEN
IPC: F16D43/18
Filed: 1985-11-08
Abstract: PURPOSE:To carry out a start and a speed change very smoothly by providing an exciting circuit for exciting an electromagnet by means of the output of a generator which is driven by a driven shaft and gradually increasing the degree of close contact. CONSTITUTION:When a driven shaft 2 starts to rotate, the output of a tachometer generator 19 is fed to electromagnets, causing these magnets 12, 13 to attract each other, while a force in the direction of weakening close contact with a clutch drum 18, is applied to clutch shoes 6, 7. The output of the tachometer generator 19 gets larger with the speed of rotation of the driven shaft 2. Accordingly, the degree of close contact is not increased rapidly, and power which is transmitted from a drive shaft 1 to the driven shaft 2 is increased only gently, enabling very smooth starting.

Title: Remote supervisory and control system
Inventor: OKAMOTO ATSUSHI
IPC: H04Q9/00
Filed: 1991-09-30
Abstract: PURPOSE:To prevent a voltage waveform from being blunted by discharging electrostatic charge stored between transmission lines by a discharging means in a power supply part at the time of switching an output voltage level from an 'H' level to an 'L' level. CONSTITUTION:A current detection circuit 22 in the power supply part detects a current flowing through a line 122 when a control part controls the connection/disconnection of a low impedance element between the lines 121, 122 and controls a transistor(TR) Q2 so as to turn off it at the time of detecting the current or turn on it at the no detection of the current. Even if floating capacity exists in the transmission line 121 when the voltage level outputted to the line 121 is switched from the 'H' level to the 'L' level, current due to charge accumulated in the floating capacity is allowed to flow to a diode D2, a resistor r3, a Zener diode ZD1, the TR Q2, and ground. Thereby the voltage waveform can be prevented from being blunted at the time of switching the voltage level from the 'H' level to the 'L' level.

In this situation, the plugging device 1 using the high temperature adsorbent is equipped to the core as an insertion into the PWR fuel and consequently, with an existence of the plugging device 1 in a flowing pass of the circulating water, an amount of radioactive nuclides decreases by adsorption of the nuclides with the high temperature absorbent, and an activity concentration also decreased. Therefore, a dose rate in a periphery of a circulating water piping diminishes and an exposure to workers decreases.

Abstract: PURPOSE:To acquire the audio signal of the satisfactory S/N even in a weak electric field section. CONSTITUTION:The SIF signals received from a PIF circuit 4 are inputted to the ceramic filter circuits 41-44. These filter circuits transmit the SIF signals of 6.5, 5.5, 6.0 or 4.5MHz bands and apply them to the switches SS1-SS3 and S3 respectively. The switches SS1-SS3, are controlled by a microcomputer 46. In a manual mode, only the output terminal of one of those circuits 41-43 is connected to a mixer 22 with other output terminals connected to a reference potential point respectively. Thus the components except a desired wave are bypassed to the reference potential point, and only the desired wave undergoes the conversion of frequency through the mixer 22. Thus an SIF signals of the satisfactory S/N is outputted from a ceramic filter circuit 45.

Title: Damper strut and strut type suspension device
Inventor: MATSUOKA YOSHINORI
IPC: B60G15/06
Filed: 1992-08-28
Abstract: PURPOSE:To reduce the height of a damper strut by enclosing a piston slidably in a tube filled with liquid, and forming such structure that the tube and the piston are not rotated relatively. CONSTITUTION:At the time of steering, slight couple of force acts upon a tie- block 26, but a rod 5 is not rotated because of being connected to the body side through an upper mount 9. A piston 4 is fixed to the rod 5, and the piston 4 constrains the rotation of an inner tube 3. An outer tube 2 and the tie-block 26 integral with the outer tube 2 are limited in rotation, so that rotary action is performed only by a rotating joint 25. A king pin axis KL can be freely adjusted in the relative position to the axis of a damper strut 1 by the tie-block 26, so that king pin inclination theta and king pin offset (d) can be set freely. The height of the damper strut can be thereby made low, and the design freedom of engine room shape, interior space, and the like is increased.
