Title: Low noise switched reluctance motor
Inventor: KIM KI-BONG
IPC: H02K19/10
Filed: 1997-06-17
Abstract: PROBLEM TO BE SOLVED: To reduce noise to be generated through driving a motor by forming stator poles and rotor poles while multiplying the number thereof specifically thereby decreasing the distribution angle of torque. SOLUTION: The stator 1 of a motor comprises N (N natural number) pairs of stator poles and the windings wound around these stator poles are connected in series such that the torque distribution period will be equal to 360 deg./2N and the rotor 2 is provided with 2N rotor poles. For example, the stator 1 is provided with twelve stator poles and the rotor 2 is provided with eight rotor poles. Consequently, the number of turns of the stator pole for each phase is halved as compared with a conventional one and the windings wound around a plurality of stator poles are connected in series. More specifically, they are connected in series such that the torque distribution period will be equal to 360 deg./2×2=90 deg.. According to the arrangement, torque distribution can be rationalized.

Title: Driven gear for automatic zooming device
Inventor: SANO KENJI
IPC: G02B7/08
Filed: 1983-09-02
Abstract: PURPOSE:To enable smooth transmission and interruption of driving power by providing a stopper which is detained by the cut ends at both ends of a clutch spring in a spring housing part to prevent the clutch spring from moving in the spring housing part. CONSTITUTION:A dovetail-shaped stopper 13 is projected in a spring housing part 3a having a recessed section formed to the inside circumferential wall of a driven gear 3. Cut ends 4a, 4b at both ends of a clutch spring 4 formed by bending a metallic wire rod to a polygonal shape collides against the stopper 13 and are thus prevented from moving. The spring 4 is therefore fixed in the part 3a of the gear 3 when a movable lens is brought to the limit position of movement by an automatic zooming operation or in the slipping condition when the lens is manually zoomed. The defective operation that may arise when the spring 4 jumps to the outside from the part 3a and the damage on the zoom ring and the gear 3 which may result from galling by the cut ends 4a, 4b of the spring 4 are thus obviated.

Filed: 1983-09-02
Abstract: PURPOSE:To obtain a resin seal type surface elastic wave element having excellent productivity and mounting capability by forming space in the neighborhood of the element by using a foamed substance having a gentle weight-loss rate curve to a temperature. CONSTITUTION:An element 4 is die-bonded with a substrate 2, and the element 4 and an external connecting terminal 1 are connected by a wire 5, and a blowing agent (such as AIBN: azobisisobutylonitrile) 11 dispersed by ethanol is applied on the surface of said element 4. The whole substrate 2 is heated at a temperature of the boiling point or higher of ethanol and the foaming starting temperature or lower of AIBN11, and only ethanol is volatilized, thus attaching AIBN12 as a solid onto the surface of said element 4. When a molten resin 16 at a temperature higher than the foaming starting point of AIBN12 is injected into a cavity section 14 from a gate section 15 for a die 13, AIBN12 starts foaming by thermal conduction from the molten resin 16, and a foaming space 9 is formed. The gate section 15 is cut, and a protective layer 10 is further formed on a product taken out of the die 13 by a thermosetting resin, thus obtaining a surface elastic wave element having excellent external appearance and reliability.

Filed: 1985-07-19
Abstract: PURPOSE:To protect surely an output transistor TR by setting the operation start of a protective circuit in accordance with the current flowing to a constant current TR, and the ratio of a detection resistance to a resistance. CONSTITUTION:When an overcurrent IE1 flows to an output TR 10, an emitter current IE2 flows to a current detecting TR 19 and the first TR 22 of the second comparing circuit 24 is made conductive to make a control TR 29 conductive, and therefore, the output of the first comparing circuit 15 is cut off and the current of the output TR 10 is limited to protect the output TR 10. With respect to the protecting operation of the protective circuit, the emitter current IE2 of the current detecting TR 19 for start of the protecting operation is determined unequivocally because EE2=(RB/RA).IO2 is true where RA is the value of a detecting resistance 20 and RB is the value of a resistance 26 and IO2 is the collector current of the second constant current TR 28.

Inventor: OOSHIMA HIROSHI
IPC: F15B11/16
Filed: 1982-09-17
Abstract: PURPOSE:To simplify the structure of an oil-pressure circuit as well as reduce the cost by a method in which oil pressure during the steady slewing period of a construction machine having a slewing function is supplied to the other working machine to shorten the cycle time of the working machine. CONSTITUTION:An oil-pressure motor 3 for slewing is connected to an oil-pressure pump 1 through a valve 2 for slewing provided with a neutral position 2a and normal and reverse slewing positions 2b and 2c and capable of performing switch operations by a pilot pressure from a pilot valve 6 to make up a slewing oil-pressure circuit.

IPC: H01L23/50
Filed: 1981-10-09
Abstract: PURPOSE:To obtain a semiconductor device which is inexpensive and has high reliability and dimension fitted to the international standard, by leading out external leads from four side surfaces of a package made of synthetic resin at intervals of 50mil. CONSTITUTION:External leads 2 are led out from four side surface of the plastic package 1 at pitches of respectively 50mil. When the pitch is 50mil, the plate thickness of the lead frame is formed thicker approx. to 0.2-0.25mm. in processing than conventional.

Title: Electric field effect type liquid crystal display element
Inventor: YOKOYA FUMIKO
IPC: G02F1/1337
Filed: 1987-06-29
Abstract: PURPOSE:To obtain a favorable display image by specifying the imidization ratio of a soluble polyimide. CONSTITUTION:The soluble polyimide is used as an orientation film and the imidization ratio of the soluble polyimide is set to >=20% and <=80%. Namely, since a polyamic acid remains in a film and it is difficult to accumulate charges in liquid crystal and the surface of the orientation film, flicker becomes very small. And since the orientation film has the effect of preventing the contamination of the liquid crystal caused by a small quantity of impurity ion and moisture, etc., or the impurity is adsorbed on the surface of the orientation film, a leakage current as an element is made small without lowering the resistance of the liquid crystal. Thus, the quality of display of the image can be improved and variance in production can be reduced.
