Title: Objective lens driver
Inventor: NAWATA YASUSHI
IPC: G11B7/09
Filed: 1990-02-20
Abstract: PURPOSE:To suppress vibration to be generated in a yoke, and to stabilize the frequency characteristic of a lens holder by attaching a non-magnetic metallic block to a gap between a bent part located at the bottom of the errection part of the yoke and a magnet. CONSTITUTION:The non-magnetic metallic block 7 is attached to a gap between the bottom of the bent part of the yoke 1 and the magnet 2. Namely, the metal lic block 7 becomes the bottom reinforcing member of the bent part of the yoke, and it can suppress the vibration of the yoke 1 around the fulcrum of the bent part. Besides, since the metallic block 7 is bonded to the magnet 2 extending over its whole length (l), it can suppress the force of a sort of twisting force consisting of reaction forces F'1N and F'2N. Thus, the disturbance of gain and a phase on the frequency characteristic of the lens holder can be kept small.

Title: Load cell and metering machine using the load cell
Inventor: MAIKERU UIRIAMU FUOODO
IPC: G01G3/16
Filed: 1993-02-04
Abstract: PURPOSE: To solve the shortcoming that ideal fixing of vibration beam type force sensor which should usually cause force only in the direction perpendicular to the fixing plane, causes in most case, force in parallel direction and gives adverse effects to performance. CONSTITUTION: A load cell for a metering machine has a vibration type force sensor and the both ends of the sensor are fixed respectively to support ends of the load cell. Each end of the sensor is fixed so as to be pushed to the support part by headed bolts 40. The bolt 40 has a screw part at a distant part from the head 41 to fit a nut causing tension force in the bolt. The noncircular cross section part has at least a cross sectional dimension larger than the cross sectional dimension of the screw part 43. The noncircular cross section part of the bolt is forcedly inserted in a hole with smaller dimension than the cross sectional dimension formed in the support part. By this, the generation of force parallel to the fixing part plane can be suppressed.

Title: Cache memory with shortened write-back access time
Inventor: SAWADA MITSUO
IPC: G06F12/08
Filed: 1989-02-21
Abstract: PURPOSE:To shorten the write-back access time by dividing a cache memory into address arrays and data arrays for reading and writing respectively and accessing only the address array and data array for writing when write-back operation is performed. CONSTITUTION:The cache memory consists separately of a part for reading from a main memory and a part for writing by a CPU. When the CPU accesses the memory for writing, a high-order address and write data are stored in the low-order address corresponding positions of the address array 2 for writing and the data array 7 for writing and then they are copied together to the main memory from the cache memory with an indication, etc., from the CPU. When the data are copied to the main memory, only the address array 2 for writing and the data array 7 for writing are referenced. Thus, when the data are written back to the main memory from the cache memory, only the address array 2 for writing and the data array 7 for writing are accessed. Consequently, the processing speed of the CPU increases.

Title: Magnetic disc device
Inventor: KAWABE SHIN
IPC: G11B33/14
Filed: 1983-03-09
Abstract: PURPOSE:To decrease a temperature difference between discs to the limit by providing a heat shield means to a recording disc fixed plate at an inlet of a wind path of a central blowing-out type circulating mechanism. CONSTITUTION:A heat insulating cover 13 fitted to the disc fixed plate 10 by, e.g., bonding is made of a plastic having a small heat conductivity. When a shaft 1 is turned, the wind produced by it passes through a filter 12 and is cooled by being introduced in the vicinity of a cover 11, and enters inside of the turning section again through a hole provided at the heat insulating cover 13 and a hole provided at the disc fixed plate 10. Thus, the area exposed directly by cold wind on the surface of the disc fixed plate 10 becomes very small. Thus, only the disc at the uppermost position is not cooled remarkably, allowing to improve significantly the temperature difference between discs.

Title: Optical recording/reproducing device
Inventor: CHATANI MASAHIKO
IPC: G11B15/60
Filed: 1987-02-23
Abstract: PURPOSE:To realize the highly accurate recording/reproducing tasks by transferring an optical tape while floating it over the guide face of a tape guide member by means of an air film without producing many recessing/projecting parts on the tape with injection of air. CONSTITUTION:A uniform air film F is formed over a wide area between a tape guide face 9 of a tape guide member 8 and an optical tape 1 by the air sprayed through air supply holes of small diameters via plural grooves 12. Thus the tape 1 is uniformly floated over the face 9 in a wide area by the film F. Thus, the tape 1 can run with no touch to the face 9. In such a way, many recessing/projecting parts produced by the spray of air can be avoided on the tape 1. Thus the focus margin of a laser beam is increased to the tape 1 and therefore the recording/reproducing characteristics can be improved.

Filed: 1984-03-05
Abstract: PURPOSE:To keep a prescribed high voltage output to a constant value by using an ROM storing a reference voltage to obtain a desired high output characteristic to a high voltage load current, against high speed high voltage load fluctuation of several horizontal periods. CONSTITUTION:A detection resistor 13 and a battery 14 detect the high load current of a flyback transformer 7 and the current is inputted to an integration circuit 15, which outputs a voltage corresponding to the integration value of the current at one horizontal period. The output voltage is converted into a digital signal at an A/D converting circuit 17 via a sample-and-hold circuit 16 and becomes an address signal to an ROM18. A reference voltage data to obtain a desired high voltage output characteristic to the high voltage load current is stored in advance in the ROM18. Thus, a data corresponding to the detected load current is read to a read output terminal of the ROM18. The data is fed to voltage control sections 9, 10 of the high voltage generating circuit via a D/A conversion circuit 19 and a filter 20.

Title: Crane turning hydraulic circuit
Inventor: HORI HIDEJI
IPC: B66C23/86
Filed: 1996-02-02
Abstract: PROBLEM TO BE SOLVED: To keep a position of an operation lever constant when turning is started by adding a pressure necessary for turning an upper rotary body to a hydraulic pump even if a discharge quantity fluctuates because of fluctuation of a rotational speed of an engine. SOLUTION: A low pressure regulating valve 10 is arranged, and a pressure of delivery oil from a pump 72 is regulated to a pressure slightly higher than a pressure necessary for driving a rotary body 75 by means of the pressure regulating valve 10 when the upper rotary body (rotary body) 75 is not operated. When a suspended cargo position is finely regulated in the turning direction, a rotational speed of an engine 71 is reduced to a slow rotation, and a delivery quantity of the pump 72 is reduced, while an operation lever 76 is slightly moved so as to supply a low pressure to a pilot chamber body 83, so that the rotary body 75 is positioned in a fine regulation position in which the rotary body 75 is slightly moved.  In this process, a turning starting position for the rotary body 75 is decided in the constant position on the basis of the position of a spool without respect to the rotational speed of the engine 71 or the discharge quantity of the pump 72. That is, the turning starting position for the rotary body 75 is decided on the basis of the operation lever 76 position, so that operation can be facilitated, and fine maneuverability can be improved.
