Title: Correlative double sampling circuit
Inventor: TAKAIWA KAN
IPC: H04N5/225
Filed: 1988-12-07
Abstract: PURPOSE:To reduce the cost of a correlative double sampling circuit even when the circuit is integrated into another circuit by providing a 1st difference voltage outputting means which outputs the difference voltage between a signal level selected by a 1st selecting means or a constant voltage and the holding voltage of 1st sample holding means. CONSTITUTION:The 1st sample holding means 7, 10, 14, and 16 hold as samples or pass through input signals and the 2nd sample holding means 6, 9, 13, and 15 hold input signals as samples. The 3rd sample holding means 8, 11, and 17 hold the input signals held as samples by the 2nd means 6, 9, 13, and 15 as samples. The 1st selecting means 18 selects either the signals held by the 3rd means 8, 11, and 17 as samples or a constant voltage and outputs the level of the signals or the difference voltage between the constant voltage and holding voltage of the 1st means 7, 10, 14, and 16 to the 1st difference voltage outputting means 20. Therefore, the cost of the correlative double sampling circuit can be reduced even when the circuit is integrated into another circuit.

Title: Spindle device
Inventor: SUGITA KAZUHIKO
IPC: B23B19/02
Filed: 1990-11-13
Abstract: PURPOSE:To prevent seizure between a flange part and a thrust bearing member by processing an end face of a workpiece by a spindle device, and by moving the spindle and the thrust bearing member in synchronization with each other in the axial direction when the spindle is exerted with a load which is larger than a spring preload. CONSTITUTION:Journal bearing member parts 12, 13 are formed at the inner periphery of journal bearing members 12, 13 fitted in a main spindle head 10. A thrust bearing member 18 is fitted between the bearing members 12, 13 so as to be slidable axially of a spindle 11. The bearing member 18 is formed therein with thrust bearing parts 19, 20 for clamping therebetween a flange part 11a formed on the spindle 11. With use of this spindle device, one end face of a workpiece is machined. When the spindle 11 is axially exerted with a load which is larger than a preload of a spring 24 due to a resistance given by the workpiece, the spring 24 is compressed so that the spindle 11 and the thrust bearing member 18 are moved simultaneously. Accordingly, it is possible to prevent occurrence of seizure between the flange part 11a and the bearing member 18.

Title: Follow-up pressure device
Inventor: NAKAYAMA SHIGEO
IPC: A61B10/00
Filed: 1986-12-25
Abstract: PURPOSE:To take out liquid helium instantaneously as required by adjusting the flow of helium gas in a liquid helium vessel by using a check valve and a solenoid valve (a valve closing at the time of conduction) in parallel and keeping helium gas at a fixed pressure higher than atmospheric pressure. CONSTITUTION:Liquid helium collects in a cryostat 13 up to a fixed quantity, a solenoid valve 3 for pressure is closed at the same time as a level sensor senses liquid helium, and a solenoid valve 4 for recovery is opened while a solenoid valve 16 for follow-up pressure is closed. This state shows the flow of helium gas from a liquid helium vessel 22 as by the arrow 20 in the figure. Since a check valve 17 is formed in constitution in which it is closed at pressure lower than a certain constant pressure and opened at pressure higher than the certain constant pressure at that time, the internal pressure of the liquid helium vessel 22 is kept at fixed pressure. When a valve 21 for a liquid helium transfer pipe is opened when liquid helium is required in the cryostat 13, liquid helium is fed instantaneously into the cryostat 13 because the internal pressure of the liquid helium vessel 22 is kept elevated.

Title: Table record retrieving system
Inventor: MUGITANI TAKAO
IPC: G06F17/30
Filed: 1990-11-14
Abstract: PURPOSE:To shorten the processing time of the whole retrieving processing for a retrieving request and a result output request generated from a user by outputting the combination of records whose satisfaction of a retrieving condition expression is decided by a deciding means to the external in response to a result output request inputted from the external out of combinations of records formed by a forming means. CONSTITUTION:A retrieving processing circuit 3 forms the combinations of records from a data base 8 while referring to respective records in plural tables to be retrieved in response to a result output request outputted from a user. When the combination of records satisfies the retrieving condition expression, the combination is returned to the user through an output circuit 2. Thereby, processing for forming the set of combinations of records to be executed in response to a retrieving request from the user can be made unnecessary. Consequently, the processing time of the whole retrieving processing for the retrieving request and result output request from the user can be shortened.

Title: Preparation of liquid dispersion, electrophotographic photoreceptor, electrophotographic method, electrophotographic device and process cartridge for electrophotographic device
Inventor: NIIMI TATSUYA
IPC: B05D7/24
Filed: 1998-10-29
Abstract: PROBLEM TO BE SOLVED: To obtain good dispersion stability by allowing the grains of a pigment to be wet-dispersed not to contain the grains of the sizes higher than a specified ratio of the media diameters and controlling the diameters of the liq. dispersion media below a specified value. SOLUTION: The grains of a pigment to be wet-dispersed do not contain the grains of >=1/2 of the media diameters (controlled to <1/2). In this case, the appropriate size of the solid dispersion media diameters is different between crushing and dispersing, and the diameters are selected in a completely opposite direction. When the solid dispersion media of <= about 2 mm are used the coarse crushing capacity is extremely decreased as compared with the case that the larger sizes are used. Accordingly, the pigment to be used is previously controlled to the size (<=1/2 of the media diameters) corresponding to the media diameters, and a stable dispersion method is given without obtaining the crushing capacity.

Title: Disk clamping device
Inventor: YOMO MAKOTO
IPC: G11B17/028
Filed: 1989-11-28
Abstract: PURPOSE:To obtain the disk clamping device in a simple assembly process, having a permanent magnet which can hardly fall off by attractively fixing the permanent magnet with magnetic attraction force operated between the permanent magnet and a ferromagnetic body. CONSTITUTION:A clamper 21 has an opening in both upward and downward directions, and its lower diameter is of a large and approximately bowl shape, and then a discoid steel plate 22 is bonded on an upper part of the clamper 21. A clamp pin 23 is fixed in the downward direction in the center of the steel plate 22, and the permanent magnet 24 in a cylindrical shape is inserted between the clamp pin 23 and the clamper 21, and is attractively fixed to the steel plate 22 by the magnetic attraction force. Then, when a disk D is clamped, attraction force is operated by the permanent magnet 24 between itself and a yoke 7, whereas since the permanent magnet 24 is nearer the steel plate 22 than the yoke 7, the attraction force with the steel plate 22 is far stronger, so that the permanent magnet 24 never falls away from the steel plate 22.

Title: Focus-error detection device
Inventor: RI TETSUU
IPC: G11B7/1372
Filed: 1994-12-13
Abstract: PURPOSE: To realize recording/reproduction insusceptible to the tilt and shift of the optical axis of reflected light by constituting a detector only of two focus lenses for focusing the reflected light from an optical disc while separating to the opposite sides of optical axis. CONSTITUTION: When a reflected light is tilted or shifted due to the inclination or aging of an optical disc 5 under on focus state, moving amount of a spot on both photodetectors 15, 16 is identical because the distance from one focus lens 12 to one photodetector 15 is the same as the distance to the other photodetector 16. Difference between signals detected based on the variation in the quantity of light on respective photodetectors caused by the moving amount of spot is canceled through a circuit means shown on the drawing. Consequently, a reflected light being tilted or shifted under on focus state causes no erroneous recognition of focus error.
