Title: Multi diamond grinding wheel for cutting rare earth magnet
Inventor: YOSHIKAWA MASAO
IPC: B24D3/00
Filed: 1996-12-16
Abstract: PROBLEM TO BE SOLVED: To cut rare earth magnet with good dimensional accuracy and stably over a long period even if the peripheral cutting edge is thin by forming a base plate of a diamond peripheral cutting edge from cemented carbide having a specified Young's modulus. SOLUTION: A peripheral cutting edge 6 for cutting rare earth magnets in which a cutting edge part 2 mainly composed of diamond abrasive grain is further fitted on a base plate 1 is used as a cutting edge of a multi diamond grinding wheel for cutting rare earth magnets. The material quality of the base plate 1 of the peripheral cutting edge 6 is cemented carbide having Young's modulus ranging from 45,000-70,000kgf/mm<2> . If the Young's modulus of the base plate 1 is less than 45,000kgf/mm<2> , bending or waviness is caused by resistance in cutting even in cemented carbide so that the base plate can not be made thinner to lose the merits of cemented carbide. If it exceeds 70,000kgf/ mm<2> , there is no problem in bending or waviness, but it is hard and brittle.

Title: Oxygen concentrator
Inventor: WATANABE HIROBUMI
IPC: C01B13/02
Filed: 1998-11-26
Abstract: PROBLEM TO BE SOLVED: To attain the miniaturization of the installation and the reduction in the power consumption without reduction of the oxygen concentration by feeding the air to the nitrogen gas adsorption tower for a prescribed time, tentatively stopping ejection of the air from the adsorption tower, before the adsorption ability of the adsorption tower lowers, and exhausting the air, after the air is sufficiently brought into contact with the adsorption tower. SOLUTION: Automatically openable valves SV3 and SV6 are arranged to the first pipe connecting the adsorption tower 1 to the product tank 11 and to the second pipe 8, respectively. When the air feeder 8 is actuated, the automatically openable SV6 is closed, while the SV3 is opened to feed the oxygen-concentrated air to the product tank 11. After a prescribed time passes, the automatically openable valve SV3 is closed, the air is sufficiently brought into contact with the zeolite adsorption tower 2 of lower adsorption ability to retain the oxygen concentration. Then, the SV6 is opened to feed the oxygen-concentrated air to the product tank 11. In the desorption process, the automatically openable valves SV1, SV4 are opened and the other valves are closed and the adsorbed nitrogen is exhausted from the air outlet 13.  The adsorption process and the desorption process are repeated to produce the oxygen-concentrated air.

Title: Photoelectric swithc circuit
Inventor: KAZAMA YASUHIRO
IPC: H03K17/78
Filed: 1991-11-25
Abstract: PURPOSE:To easily confirm the operation at a tip of a light emitting device or an optical fiber by changing a duty ratio of a light emitting pulse corresponding to a specific level of an input signal at a light receiving device of a photoelectric switch driven by a visual light emitting pulse. CONSTITUTION:A switching circuit 6 is provided in a basic configuration comprising a light emitting device and a light receiving device. Then a duty ratio of the oscillation in an oscillation circuit 2 is changed by a signal (a) from an output circuit 5 and the duty ratio of the light emitting pulse is changed. That is, since only the duty ratio of the light emitting pulse is changed, the light emission of an LED 1 at the light incidence is brighter in the case of comparison at the light incidence and the light interruption. When an input signal level exceeds a prescribed value at the light incidence by the output circuit 5, an operation display light 7 is lighted. Thus, when the timing of the output of the signal (a) from the output circuit 5 is set equal to the lighting timing of the display light 7, the brightness of the LED 1 is changed depending on the operating level.

Filed: 1993-12-28
Abstract: PURPOSE:To controls data to have a prescribed bit number and to decide an optimum quantization width by modeling a relation among a quantization width, a coding bit number and distortion and using the model so as to obtain the quantization width minimizing picture coding distortion. CONSTITUTION:A model decision section 21 uses plural quantization sections arranged in parallel to apply quantization to data with different quantization width, and calculates a bit number produced for each quantization. Then the generated bit number is expressed as a function of the quantization width and a parameter included in the function is decided. Furthermore, picture data to be quantized are subject to inverse quantization at a corresponding inverse quantization section and distortion with respect to the quantization width is calculated based on the data before quantization and data subject to inverse quantization. Then the distortion is expressed as a function of the quantization width and a parameter included in the function is decided. A quantization width decision section 22 uses two mathematical models obtained in the decision section 21 earlier to control bit number after compression into an allocated bit number and decides the quantization width minimizing the distortion.

Title: Drum type washing machine
Inventor: KAWAGUCHI TOMOYA
IPC: D06F23/02
Filed: 1998-11-27
Abstract: PROBLEM TO BE SOLVED: To start up water extraction by speedily dispersing entangled things being washed onto the internal circular wall of a drum. SOLUTION: From the condition in which a drum is stopped, a PWM duty ratio for determining a voltage applied to a motor which rotates and drives a drum is gradually increased, (S2-S4). After a rotating speed reaches 45 rpm, the PWM duty ratio is increased with a greater increasing rate, (S6-S8). During a period of time when the drum slowly rotates, things being washed become disentangled and air enters empty spaces between the things being washed. Then, during a period of time when the rotating speed increases rapidly, a mass of the things being washed are dispersed, spread over the entire internal circular wall face of the drum, and stuck to it by centrifugal force. As a result, an eccentric load becomes small.
