Title: Piping circuit for air compressor
Inventor: YOSHIDA SHIGERU
IPC: F04B41/00
Filed: 1990-06-07
Abstract: PURPOSE:To eliminate the environment pollution due to lubricating oil by interposing a switching valve in a discharge line thereby closing the communication between a discharge hole and an air drier while making the air drier be opened to the atmosphere. CONSTITUTION:As an air tank 2 reaches a specified air pressure, a pressure regulator 3 transmits the air pressure to a pilot line 3a. Consequently, an unloader valve 1a is actuated thereby causing an air compressure 1 to be an unload state. A signal air pressure generated in a displacement chamber or branch pipe 3b acts an air drier 6 to open a valve of a port. Furthermore, by the signal transmission to the pilot line 3a, there is generated a signal air pressure at a branch pipe 3c, so that a switching valve 5 is switched into a switching position 5B. As a result, lubricating oil is returned from the line 1b through the switching position 5B to a crank chamber serving as a lubricating oil storing portion of the air compressor 1, to close the communication between the port of the air drier 6 and the line 1b.

Title: Loading and unloading device of magnetic sheet pack
Inventor: HARASE TOSHIKATSU
IPC: G11B17/04
Filed: 1984-07-16
Abstract: PURPOSE:To attach surely the center core of a magnetic sheet to a drive shaft by using a pressure member which secures a noncontact state with the center core in a normal close mode of a cover and then a contact state with the center core when the cover is opened slightly. CONSTITUTION:When an upper cover 28 containing a magnetic sheet pack 10 is pushed down to a main body 24, a pin 100 of the cover 28 is fitted into a lock groove 92. Then a projected bar 95 of a lever 82 turns a stopper 86 clockwise to release the hook between the stopper 86 and a stage part 124 of a holding lever 84. In this overstroke state a pressure pin 76 presses a center core 14 and then to a drive shaft 32 surely. When the force applied to the cover 28 is released, the lever 82 is reset slightly. Then a folded part 108 of the lever 84 is set into a groove 94, and a switch 116 is closed with a left shift of the lever 84. Thus a sheet 12 is revolved. Therefore, the core 14 is attached surely to the shaft 32 with an overstroke action.

Title: Cache data checking system
Inventor: KAMEYAMA KAZUYOSHI
IPC: G06F12/16
Filed: 1989-06-09
Abstract: PURPOSE:To attain the effective analyses of faults by performing the comparison between both data on a cache and a main memory and keeping the address and these two data as they are if no coincidence is obtained between both data. CONSTITUTION:An address tag is read out of an address array 3 by an index of an address register 1 and compared with an address tag of the register 1 by a comparator 6. If no coincidence is obtained between both address tags, a mishit is decided, the process is transferred to a reading operation of a main memory via the hit/mishit control parts 8 and 9. In this case, the comparison to be carried out by a data check control part 5 via a comparator 12 is inhibited since such comparison is useless. The part 5 performs the control so as to prevent the update of an address buffer 2 and a data buffer 10 during the check given to the data of a cache and a main memory. As a result, the address and both data of the cache and the main memory are kept as they are.

Title: Static focusing/static deflection type image pick-up device
Inventor: NAITO MASAO
IPC: H04N5/228
Filed: 1986-06-24
Abstract: PURPOSE:To decrease the power consumption by keeping the peak value of the deflecting voltage of an electrode related to deflection constant, lowering at least the voltage of the electrode related to the focusing in keeping the ratio as it is an over-scanning it. CONSTITUTION:A focusing and deflecting are determined by electrode voltages Vg3-Vg6 applied to grids G3-V6 to a cathode voltage Vc. Until an electronic beam generated from a cathode C arrives at a target T, a picture is not rotated. Consequently, a deflecting waveform amplitude is constantly kept, electrode voltages Vg3-Vg6 are descended while the ratio is kept and the deflecting size becomes larger. At such a time, the electrode voltages Vg3-Vg6 are descended while the ratio is kept, and therefore, a focus is kept constant and a picture will not rotate. Consequently, thus, by keeping constantly the deflecting waveform amplitude and lowering the electrode voltage Vg3-Vg6 while the ratio is kept, thereby executing the overscanning action.

Title: Contact detection method and apparatus for electroconductive object of underground buried tube
Inventor: MORI KUNIHIRO
IPC: G01V3/06
Filed: 1988-06-15
Abstract: PURPOSE:To enable accurate detection of a possible contact of an electrically conductive object with a buried tube, free from effect of noise current, by monitoring an input impedance of the underground buried tube as viewed from a proper point to detect a drop therein. CONSTITUTION:When an electrically conductive object 3 of an excavating machine gets in contact with a buried tube 2 at a point (a) at a time t1 to cause a leak of a current Ie through the object 3, an input impedance Z of the buried tube 2 lowers as viewed from a point 1. This impedance Z is so free from effect of a noise current that there is little leak caused by other reasons than the contact of the object 3 with the buried tube 2. Therefore, only monitoring of the impedance Z of the buried tube 2 viewed from the point 1 ensures accurate detection of the contact of the object 3 with the buried tube 2 by a change therein. To achieve the monitoring, an AC signal current supply means 4 to the buried tube 2 is provided with detecting means 5 and 6 for a supply current and voltage while the impedance Z of the buried tube 2 is derived from detection signals of the means 5 and 6 to be checked by an input impedance monitoring means 7.

Abstract: PROBLEM TO BE SOLVED: To remove noise by positioning signal wavelength suitably in the transmission band of a filter, to increase reception sensitivity, and to improve transmission characteristics by performing sweep control over the transmission center wavelength of a variable-wavelength filter so that a low frequency signal superposed on a transmission side is detected. SOLUTION: A transmission-side terminal station device 1 amplifies with an optical postamplifier 5 a signal light modulated with a data signal from an information signal input terminal 6, applies AM modulation with a low-frequency signal from a low-frequency signal generator 4, performs amplification by an optical direct amplifier repeater 9, and inputs the resulting signal to a reception-side terminal station device 16. After amplified by an optical preamplifier 10, the signal is inputted to a variable- wavelength optical fiber 11 and the transmitted light is converted by an optoelectric converter 12 into an electric signal, which is supplied to a low-frequency signal detector 13.  When the low-frequency signal is not detected, a control part 14 sweeps the center wavelength by controlling the variable-wavelength optical filter 11 so that the low-frequency signal is most suitably detected.
