Patent JP-S6479508-A (JP)
Title: Liquid fuel combustion device
Inventor: ISHIKAWA TOSHIJI
IPC: F23D7/00
Filed: 1987-09-21
Abstract: PURPOSE:To realize a stable concentration of mixture gas by a method wherein a side wall surface of a gasification cylinder opposing to the extremity end of a nozzle is inclined as it may approach the nozzle as it moves toward the bottom surface of the gasification cylinder and kerosene particles are prevented from flowing down to the bottom surface of the gasification cylinder under a variation in discharging pressure. CONSTITUTION:Fuel injected from a nozzle 10 into a gasification cylinder 1 has a higher pump discharging pressure in case of a high heating calories (a high combustion) and is injected as shown at A, and even if a low discharging pressure at a low heating calorie (a weak combustion) is applied, it may abut against a side wall surface 1a of the gasification cylinder 1. This fuel is instantaneously gasified at a hot temperature part of the side wall surface 1a of the gasification cylinder 1 ranging from the high combustion to the low combustion and so no oil leakage caused by a delay in gasification at the low temperature side of the bottom part of the gasification cylinder 1 is found. Accordingly, the gasification of the fuel has no delay in time and a concentration of the mixture gas is quite stable and a pulsating combustion is not carried out, resulting in that a yellow flame, odor, soot and CO or the like caused by an incomplete combustion are substantially improved in their generation.

Title: Proportional solenoid valve
Inventor: MIYAGI JUNICHI
IPC: F04B1/26
Filed: 1987-09-21
Abstract: PURPOSE:To improve operational response with low electromagnetic force by converting electromagnetic force temporarily into fluid pressure then operating a main spool with the fluid pressure. CONSTITUTION:Upon operation of an auxiliary spool 15s with electromagnetic force proportional to an input current, control pressure is produced from a control pressure producing means 25 corresponding to the operation of the auxiliary spool 15s so as to operate a main spool 15M. Even when the control pressure produced from the control pressure producing means 25 is low, high pressure is applied onto the main spool 15M if the main spool 15M has a large control pressure working area, and thereby the main spool 15M can function quickly with no delay.

Title: Infrared ray picture device
Inventor: UCHIDA SUMIHIRO
IPC: G01J1/02
Filed: 1997-09-02
Abstract: PROBLEM TO BE SOLVED: To miniaturized and lighten a mechanism part for correcting dispersion in responsiveness and dark current of an infrared ray detecting element, related to an infrared ray picture device. SOLUTION: A dark current dispersion detecting mirror 1 and a responsiveness dispersion detecting temperature reference plate 2 are so configured with a mirror driving means 4 and a temperature reference plate driving means 6, respectively, that they are inserted square each other at the same position shielding an incident optical path 5. A position which shields the incident optical path 5 is at the front surface of an infrared ray detector 3 or a point on the optical path of an optical system.  When dark current dispersion is corrected, the mirror driving means 4 moves the mirror 1 horizontally, and makes the mirror 1 reflect a low temperature energy which the means itself radiates to be incident on the infrared ray detector 3, while at time of correction of responsiveness dispersion, the temperature reference plate driving means 6 moves the temperature reference plate 2 vertically, and makes the radiation energy of the temperature reference plate 2 incident on the infrared ray detector 3. A correction process means 7 corrects DC offset of each of the infrared ray detecting elements.

Title: Operating device for passenger conveyor
Inventor: KURIOKA YUTAKA
IPC: B66B25/00
Filed: 1997-09-02
Abstract: PROBLEM TO BE SOLVED: To prevent a passenger conveyor from being stopped on the way by arranging a passenger detecting device in a space not less than at least the width of a landing, and composing a multibeam sensor of a light projecting part and a light receiving part extended in a horizontal direction. SOLUTION: When a passenger intercepts beams 9 at a landing port 4, a contact is closed. When an automatic operation changeover switch is closed, a relay is excited to close the contact, so that a conductive circuit is formed to excite a timer relay. While the passenger intercepts the beams 9, the closed state of the contact continues, and this state continues until the passenger gets on a footstep 3. When the passenger gets on the footstep 3 to terminate interception of the beams 9, the timer relay starts counting and stops in about ten seconds after the passenger gets off from a descending port 5. Since counting of the timer relay is not started while the passenger is at the landing port 4, even in case an old person or the like stays at the landing port 4 after the start of a passenger conveyor and then gets on the footstep 3, the old person can be positively transferred up to the descending port 5.

IPC: H02H5/04
Filed: 1993-08-30
Abstract: PURPOSE:To provide a protective circuit for electric equipment in which abnormally heated state can be stopped positively by a simple and inexpensive method. CONSTITUTION:Upon occurrence of short circuit of a motor or abnormality in an actuator due to trouble in the circuit, overcurrent flows into a transistor 22 which is thereby heated to cause temperature rise. Consequently, the temperature of element in constant voltage diodes 16, 17, having negative temperature coefficient characteristics and coupled thermally with the transistor 22, rises and the breakdown voltage thereof drops. Upon receiving a voltage Vcc dropped by the breakdown voltage, a voltage detection IC 18 delivers a 'LOW' signal to a CPU 19 which hard resets the electric appliance.

IPC: G06Q50/04
Filed: 1997-09-03
Abstract: PROBLEM TO BE SOLVED: To make a production limit considering loads of the whole of a plurality of facilitis included on a production line by computing facility loads applied to a plurality of facilities included on a production line at each unit term based on the charging time of material, and changing the charging time based on the computed result. SOLUTION: The intial value of a hot rolling day of each lot is decided in the range of term capable of hot rolling (S6). Against this initial value, loads of respective facilities at every day are computed based on passing process information (S7). Because capacities of the respective facilities of every day are limited, load weight of over-capacity portion of the respective facilities of every day are determined, referring to processing capacity in one day of every facility. The initial value of a hot rolling day at every lot is changed (S8) so as to reduce the total quantity of the over-capacity load. Against the initial value of the changed hot rolling day, the load over-capacity load is again computed, and this process is repeated until the over-capacity load becomes the minimum value (S9). Finally a hot rolling production limit is outpu (S10).
