Title: Stator yoke
Inventor: KAZAMA SABUROU
IPC: H02K29/00
Filed: 1981-06-25
Abstract: PURPOSE:To provide high and smooth rotation with small, light-weight and simple structure and improve the efficiency of a motor by forming the thickness of the outer peripheral side of a stator yoke thicker than that of an inner peripheral side. CONSTITUTION:A circular notch 18 is formed at the inner periphery of a stator yoke 3', and the thickness of the inner periphery 16 is formed thinner than the outer periphery 15. When the thickness of the inner periphery 16 is formed thinner than the outer periphery 15, the reactance of a magnetic circuit formed between a stator magnet 1 and a stator yoke 3' becomes high at the inner periphery 16 and low at the outer periphery 15. Accordingly, the magnetic flux 25 produced from the pole surface of the magnet 1 is attracted to the outer periphery 15 side, so as to become high density at the air gap of the outer periphery 15 side and low density at the inner periphery 16 side. In this manner, the weight  of the yoke can be reduced, and cogging torque is reduced, thereby obtaining  high and smooth rotation and improving the efficiency of the motor.

Filed: 1983-06-03
Abstract: PURPOSE:To prevent the effect given to a processor of the active side with an information processing system which performs double structure operation, by pushing a package replacement request key to control a signal line inhibiting circuit. CONSTITUTION:A package replacement request key 15 of a console device 3 connected to a processor 1 is switched on when the processor 1 is in an action mode and also in an asynchronous operation mode. Thus the outputs of an action display flip-flop 14, a synchronous mode display flip-flop 13 and the key 15 are set at ''1'', ''0'' and ''0'' respectively.

Filed: 1998-03-27
Abstract: PROBLEM TO BE SOLVED: To improve the heat transfer efficiency of a heat exchanger by providing a plate-shaped slit fin with a rectifying function on a heat transfer fin and stabilizing air flow. SOLUTION: A heat exchanger is formed while a slit fin 6a and a slit fin 6b on a heat transfer fin are provided at the front of a heat transfer pipe 4 and the gap between the slit fins in its vertical direction is narrowed. The slit fin 7a and the slit fin 7b are arranged with a constant interval while pinching the heat transfer pipe 4. Then, plate-shaped slit fins 8 (8a, 8b) with an equalizing function are pushed and formed at a position being equivalent to the reverse side of the heat transfer pipe 4 against air flow. When air flow occurs, the contact of air to the heat transfer pipe 4 is improved for improving the transfer efficiency of heat since the gap between the slit fins 6a and 6b being located at the front of the heat transfer pipe 4 is narrowed.  The plate- shaped slit fins 8a and 8b located at the reverse side of the heat transfer pipe 4 are formed so that they restrict air, the air flow is deflected to a region where the heat transfer property of air is poor at the reverse side of the heat transfer pipe 4 and at the same time the slit fins 8a and 8b have a function as a rectifying plate, thus stabilizing the air flow.

Title: Refrigerating apparatus
Inventor: TAKAICHI KENJI
IPC: F25B1/00
Filed: 1995-04-24
Abstract: PURPOSE: To avoid the occurrence of grave accidents such as firing or explosion of a combustible HC refrigerant leaked by mixing a refrigerating machine oil sealed into a refrigerating cycle with a phosphor-containing organic substance such as dibutyl acid phosphate. CONSTITUTION: A refrigerating machine oil 18 is sealed into a compressor 9 mixed with an phosphor-containing organic substance such as dibutyl acid phosphate. When a HC refrigerant 13 leaks from a refrigerating cycle, the refrigerating machine oil 18 also leaks and the phosphor-containing organic substance such as dibutyl acid phosphate volatilizes from the refrigerating machine oil 18. As this substance has odor even in a very small quantity, the leakage of the HC refrigerant 13 can be detected thereby allowing avoiding of gave accidents such as firing or explosion of the HC refrigerant 13. When supplied to a lubricating surface of the compressor 9, the refrigerating machine oil 18 mixed with the phosphor-containing organic substance such as dibutyl acid phosphate acts as extreme-pressure agent under such a severe condition as boundary lubrication thereby preventing wear.

Filed: 1990-04-13
Abstract: PURPOSE:To minimize an average value of dispersion in NF against the dispersion in a signal source impedance by converting the characteristic impedance of an input matching circuit into an impedance supplied at a cross point between a equi-noise exponent circle being a plot of a same noise figure and a straight line tying an averaged dispersion of an optimum signal source impedance and the center point of a Smith chart.

Since the matching point is shifted in a direction in which intervals of equi-noise exponent circles are made thin in a low noise amplifier employing the input matching circuit, the mean value of the NF of the amplifier caused by the dispersion in GAMMAopt is minimized.

Filed: 1990-04-13
Abstract: PURPOSE:To attain the nonlinear normalization of characters with high accuracy and in a short processing time by deciding the corresponding points before and after the normalization with use of a specific coordinate transformation function and shifting the picture element value. CONSTITUTION:A RAM 100 is provided to store the unnormalized character images together with a RAM 102 which stores the normalized character images, a processing part 104 which carries out the normalization processing, a RAM 106 which offers a work storage area of the part 104, a ROM 108 which stores a weighting function for a key coordinate transformation function, and a RAM 110 which stores a coordinate transformation function against an entire character image. Then the distortion of a character is defined by the uneven characteristic value caused on a character image. Then the characteristic value of each point of the character image is obtained and the distribution of the characteristic value is obtained for each area. The decided key coordinate transformation function of each area is multiplied by the weighting function and combined to obtain the coordinate transformation functions for the entire character image. Based on these transformation functions, the corresponding points are decided before and after normalization and the picture element value is moved. Thus the character images can be obtained in a short time after normalization.
