Title: Vacuum pump
Inventor: INUI KATSUHIKO
IPC: F04C18/30
Filed: 1984-02-29
Abstract: PURPOSE:To obtain a compact vacuum pump having a large capacity by allowing the first and the second pump chambers formed inside and outside an inner cylinder to separately perform suction and exhaust operations by the movement in one cycle of a single turning vane and allowing each capacity to be added. CONSTITUTION:A suction port S always communicates to the capacity increasing chamber IIb of the second pump chamber II, and allows the capacity increasing chamber IIa to communicate to the capacity increasing chamber I b of the first pump chamber I , and the capacity reducing chamber IIa of the second pump chamber II communicates to the capacity reducing chamber I a of the first pump chamber I through a valve 10 which is opened in a prescribed timing at the position close to the turning side of a vane 6. Further, the above- described capacity reducing chamber I a communicates to an exhaust port P through a check valve 11. With such constitution, the first and the second pump chambers I and II formed inside and outside an inner cylinder 4 separately perform suction and exhaust operations in the movement in one cycle of a single turning vane 6, and each capacity is added, and the function equal to that of a two-stage pump is developed, and high compression ratio can be obtained, and high vacuum can be achieved, and a compact vacuum pump having a high capacity can be obtained.

Title: Turbomolecular pump
Inventor: FURUICHI YASUTAKA
IPC: F04D19/04
Filed: 1984-02-29
Abstract: PURPOSE:To spread the exhaust-enable range of a pump to the lower vacuum side by forming a spiral groove in the opposite direction to a spiral groove on a screw rotor, onto the inner peripheral surface of the peripheral wall surrounding the screw rotor, and increasing the compression-ratio increasing function for the screw rotor part. CONSTITUTION:On a screw rotor 5, not only a spiral groove 5a formed onto the outer peripheral surface, but a spiral groove 7a in the opposite direction to the spiral groove 5a is formed onto the peripheral wall surrounding the spiral groove 5a, keeping a minute gap, namely onto the inner surface of a spacer 7 fitted onto the inner peripheral surface of an outer frame 6 in the application drawing. Therefore, the spiral grooves 5a and 7a cross each other at each position turning by 180 deg., and the combined body parts 8a, 8b... constituted of the combined spaces of the grooves 5a and 7a are formed at the above-described positions as shown in the figure. These parts 8a, 8b... speedily revolve and lower to an exhaust port B side as the screw rotor 5 revolves at a high speed, and the combined body part pushes-out gas particles very strongly. Therefore, the exhaust speed efficiency is increased in comparison with the conventional.

Abstract: PURPOSE:To make an amplitude frequency characteristic variable in a simple circuit constitution by using a Butterworth type low-pass filter to select variably factor values of factor equipments so that pole positions may be moved in parallel to the real axis within a prescribed range arbitrarily. CONSTITUTION:By varying factor values of factor equipments 6, 7, 11, 12 and 13 of a general Butterworth type low-pass filter, pole positions are moved to arbitrary positions in parallel to the real axis in a unit circle on the S plane and within a prescribed range. That is, poles q1, q2, and q3 are moved to poles p1, p2 and p3 and the frequency characteristic of the figital dilter is changed in the arrow direction accompanied with this movement, and dip parts and peak parts appear. Then, the sharpening degree can be varied to a desired value by the control of factor values of factor equipments, and a digital filter which output input signals with a desired frequency characteristic added can be obtained.

Title: Power photo-composite submarine cable
Inventor: OKADA NAOKI
IPC: G02B6/46
Filed: 1991-02-08
Abstract: PURPOSE:To improve respective characteristics such as side-pressure-resistant characteristic, bending characteristic, or twisting characteristic by providing, on the side face of PE sheath, a spiral groove whose twisting direction is the same as that of an iron wire armor and in which the relationship between a pitch and a pitch diameter is specified. CONSTITUTION:A spiral groove 23 is provided in the plastic sheath 22 of a power cable 12 in such a way that an optical fiber unit 24 is housed therein. The unit 24 is not fixed by a presser winding 25 so that it moves inside the groove so as to can cel a tensile and a compressive stresses arising in and outside of a neutral plane upon bending. The swirl direction of the groove 23 is designed to be the same as the twist direction of an iron wire armor 34, and the relational equation such as n/m=D/d is designed to be satisfied when the ratio between a twist pitch 'P' and the pitch diameter 'D' of the armor 34 is designated to be 'n' and the ratio between a spiral pitch 'p' and a pitch diameter 'd' of the groove 23 is designated to be 'm'. When a composite cable 10 is twisted, the length of the groove 23 is substantially kept constant, thus no stress is applied to the unit 24 so that a lowering of life and a degradation of transmission loss can be prevented.

Title: Developer cartridge
Inventor: TSURUOKA RYOICHI
IPC: G03G15/08
Filed: 1998-02-05
Abstract: PROBLEM TO BE SOLVED: To provide a developer cartridge constituted so that such possibility that a spiral agitator abuts on the inside wall of a developer housing barrel can be drastically reduced by reducing the decentering state of a spiral part even when large rotational load is imposed on the developer supply port side of the spiral agitator. SOLUTION: The spiral agitator is composed of a rotary shaft 212 for transmitting the driving force of a coupling 202 and the spiral part 213 whose one end part is coupled to the end part of the shaft 121 and which is wound round the rotary shaft as an axial center. Then, one point 214 of the end part of the spiral part 213 on the coupling 202 side is fixed to the shaft 212 by welding, soldering and the like. Thus, the rigidity (mechanical strength) of the whole spiral agitator is made strong and such possibility that the spiral agitator abuts on the inside wall of the developer housing barrel is reduced even when the large rotational load is imposed on the spiral agitator.

Title: Semiconductor memory
Inventor: OKAMURA JUNICHI
IPC: G11C11/407
Filed: 1996-02-27
Abstract: PROBLEM TO BE SOLVED: To shorten the precharge time while preventing malfunction and thereby further shorten the recycle time of memory operation. SOLUTION: An equalizing control circuit 16 inputs a signal X-ADR and a signal Wlact from a predecoder 13. The equalizing control circuit 16 includes a latch circuit 160 and outputs an equalize control signal EQS from the conditions of two signals. The latch circuit 160 in the equalizing control circuit 16 is set (inactivation of equalizing signal) by the signal X-ADR activated by activation of the internal RAS signal and holds this condition. The latch circuit 160 is reset (activation of the equalize signal) by the signal output due to inactivation of the word line by the word line active signal Wlact. Therefore, control can be done without direct dependence on the internal RAS signal.

Abstract: PURPOSE:To prevent restoration of drive power from being delayed by reducing the drive power when slip ratio exceeds a 1st setting value and restoring the drive power when the slip ratio becomes smaller than a 2nd setting value which is greater than the 1st setting value. CONSTITUTION:Arranging revolution detecting means A and B for detecting respective revolutions of a drive wheel and a driven wheel, a slip ratio between a tire and a road surface is calculated with a slip ratio calculating means C according to the detected revolutions of the drive and driven wheels. While the calculated slip ratio is discriminated with a 1st slip ratio discriminating means D if the ratio is greater than a 1st setting value or not, a 2nd slip ratio discriminating means E discriminates the calculated slip ratio if it is smaller than a 2nd setting value (greater than the 1st setting value) or not. Drive power is controlled to be reduced when the slip ratio exceeds the 1st setting value and to be restored when the slip ratio becomes smaller than the 2nd setting value by means of a drive power control means F.
