Patent JP-H1113915-A (JP)
Title: Gas cutoff valve
Inventor: ISHIGAKI YOICHIRO
IPC: F16K17/36
Filed: 1997-06-24
Abstract: PROBLEM TO BE SOLVED: To prevent valve opening until a burner is surely turned off when vibration occurs by providing a magnetic means for applying a magnetic force to a moving piece made of a magnetic material in a device for keeping a valve open while the moving piece is placed on an inclined section provided in a main body. SOLUTION: When vibration is generated by an earthquake or the like and a moving piece 3 is moved up on an inclined section 22 and removed from a communication hole 23, as the moving piece 3 approaches the inner peripheral surface 21 of a moving piece room 2, the piece 3 is attached to, among permanent magnets in a magnet body 6 surrounding the outer peripheral surface of the moving piece room 2, a nearest permanent magnet. Then, the piece 3 is kicked back after clashing with the inner peripheral surface 21 of the piece room 2, but a track is bent by a magnetic force, a probability of the piece 3 passing on the communication hole 23 immediately after being kicked back is very small.  If the piece 3 is not separated from the inner peripheral surface 21 because of the magnetic force of the permanent magnet, by pressing a guide catch 63 to reduce the magnetic force applied on the piece 3, the piece 3 is returned to the communication hole 23 by its own weight.

Title: Constant speed traveling device for car
Inventor: SAKAKIBARA NAOJI
IPC: B60K31/00
Filed: 1982-09-24
Abstract: PURPOSE:To obtain stable fixed-speed car traveling by increasing the horsepower, when horsepower needs to be increased while a car is traveling at an fixed speed by means of an overdrive, by making the throttle opening larger and by cutting the overdrive to the downshift after the opening becomes larger than the specified one. CONSTITUTION:In a state of fixed-speed traveling, the output signal from a self- supporting circuit 120 reads ''H'' while a hydraulic switch 102 is turned ON to set the operation at the outdrive. When the car speed is lowered on a slope, a fixed-speed traveling unit operates to make an actuator increase the throttle valve opening. When the opening becomes larger than the specified one, a throttle sensor 80 produces a signal ''H''. Accordingly, the output from an AND circuit 110 turns from ''L'' to ''H'', and a normal close relay 210 is opened, suspending electrification to a solenoid 103. As a result, the overdrive is cut to be downshifted to the third gear. With this contrivance, the horsepower of the car can be increased for quick acceleration.

Title: Structure of rotary heat regenerator core
Inventor: MATSUDAIRA NOBUYASU
IPC: F02C7/105
Filed: 1994-06-27
Abstract: PURPOSE:To enhance the bending strength of a cell and prevent the generation of a drop in the performance of a heat exchanger by constituting a core with a wavy cell where a cell connected in the shape of honey comb is formed in such a fashion that its central part and its connection part may be thicker- walled than any other locations. CONSTITUTION:A heat exchanger element of a core consists of a cell 23 which is connected in honey comb shape where the cell 23 is made of a high heat resistant and high hardwearing material during high temperature. Each cell 23 is formed so that its central part 23a may be thickerwalled continuously from both sides while a connection end 23 on both sides is adapted be thick- walled. What is more, the connection part rounded with a radius R is smoothly connected to its counterpart wall. The thickness t1 of the wall thickness of the central part 23a is so selected that it may be 1.3 times larger than the thickness tc of the thin walled section of the central part on both sides, thereby constituting a wavy type cell. In addition, the radius R of the connection part 23b is preferred to be larger with a view to prevent stress concentration. However, it should be set in the range where a marked difference is not produced due to limitations imposed during the formation of the core.

Title: Device and method for voice analysis and storage medium which records voice analysis program
Inventor: YOSHIOKA YASUO
IPC: G10L25/93
Filed: 1998-06-15
Abstract: PROBLEM TO BE SOLVED: To precisely conduct a voiced/voiceless discrimination. SOLUTION: First, a voiced/voiceless discrimination is conducted in an on- time axis detecting section 4. If it is not discriminated to be voiceless, a voiced/ voiceless discrimination is conducted in an on-frequency axis detecting section 7. Moreover, a pitch detection is conducted in a pitch detecting section 8 only for the frame, which is not discriminated to be voiceless in the sections 4 and 7, and a voiced/voiceless discrimination is again conducted. In the section 4, a voiced/voiceless discrimination is conducted not only with the discrimination based on the number of zero crossings but also with the consideration on the energy element. Thus, a fricative sound is discriminated with a better precision.  In the section 7, a voiced/voiceless discrimination is conducted aiming at high frequency components and the sound, which can not be a voiced sound of a normal voice, is eliminated as a voiceless sound.

Title: Lubricating device of continuously variable transmission
Inventor: HISAMURA HARUYOSHI
IPC: F16H9/18
Filed: 1990-06-26
Abstract: PURPOSE:To efficiently lubricate a transmission with a small quantity of lubricating oil by varying the direction of a nozzle for supplying lubricating oil to a contacting portion between a pulley and a V-belt in such a manner as to always supply lubricating oil to a position where the V-belt is wrapped in the pulley according to a speed change ratio. CONSTITUTION:When a movable cone member 18 moves closer to a fixed cone member 12 (that is, the speed change ratio is increased), a speed change ratio detecting member 32 moves to the left to work on a cam face 34a, whereby a nozzle supporting member 34 is rotated counter-clockwise so that a nozzle 36 is put in the state of supplying lubricating oil to the outside diameter sides of the fixed cone member 12 and the movable cone member 18. On the contrary, when the speed change ratio is decreased, the movable cone member 18 moves to the right, whereby the nozzle supporting member 34 is rotated clockwise so that the nozzle 36 is put in the state of supplying lubricating oil to the inside diameter sides of the fixed cone member 12 and the movable cone member 18. Thus, lubricating oil can be supplied a portion where a V-belt is wrapped in a pulley.

Filed: 1985-07-31
Abstract: PURPOSE:To make it possible to appreciate the normality of error detecting circuits by writing error detection suppressing combination patterns for plural error detecting circuits in an error detecting suppressing circuit. CONSTITUTION:After selecting diagnosis data PD by a selector 5, the operation is switched to a diagnosis mode. Then, control signal C is inputted from a microprocessor 200 to an error detection suppressing circuit 100. On the basis of the control signal C, a suppressing combination patterns are written in FFs 101-104 of the circuit 100. The function of the error detecting circuit 31 is invalidated by the suppressing combination pattern to suppress error detection. Thereby, the processor 200 can recognize whether the detecting circuit 31 is normal or not by recognizing whether the detecting circuit 31 holds an error result or not. The normality of the detecting circuits 32-34 can be also appreciated by applying similar operation to the detecting circuits 32-34.
