Title: Facsimile equipment and its redialing method
Inventor: WATANABE YUICHI
IPC: H04N1/32
Filed: 1995-02-15
Abstract: PURPOSE: To improve operation by displaying a prescribed number of destination numbers and destination IDs stored in a memory in the new call order through the depression of a redial key and rearranging the call order when a displayed destination is selected and after it is called. CONSTITUTION: A CPU 15 controls each section according to each program in a ROM 16 and uses a ten-key (a), a one-touch key (b) and a redial key (c) of an entry section 14 to make a call. For example, when the number of redial destinations of a redial management area 12 is five and the keys a, b are used to make a call to each company in the order of A, I, U, E, O, the priority is set in the order of A, I, U, E, O. The destination IDs and telephone numbers in this order are registered in the area 12 and the key (c) is depressed, displayed on a display section 7, and a selection means 23 selects a destination E, then the telephone number of the destination E is dialed. Then the priority is changed into E, A, I, U and the processing is finished. Since the registration by using the key (b) or the like is not required, the operability is improved.

Title: Secondary air supply device for engine
Inventor: TANAKA KAZUO
IPC: F01N3/34
Filed: 1992-02-14
Abstract: PURPOSE:To enhance the activation of a catalyst in a catalytic converter, and to prevent the deterioration of EM by providing a heat-accumulating means capable of accumulating produced heat for a prescribed period of time, a means for detecting the cold state of an engine, and a secondary air supply means, and by heating the secondary air with the heat accumulated in the heat- accumulating means and then supplying it to the exhaust system. CONSTITUTION:Intake air is passed through an intake passage 1, and burns fuel in an engine 3, and then becomes exhaust gas and is discharged through an exhaust passage 5. A secondary air passage 17 is provided with a heat battery 27 being a heat-accumulating means. In the inside of this heat battery 27, a heat-accumulating agent is filled. Since the heat produced by the engine 3 that has been operated hitherto is accumulated in the heat-accumulating agent of the heat battery 27, secondary air can be sufficiently heated even in the case of cold operation, for instance, in the case of engine starting with a low outside air temperature. Thus, the temperature of a catalytic converter 15 can be maintained for increasing the activation of the catalyst, so that engine modification (EM) can be enhanced.

Title: Credit processing terminal equipment
Inventor: DEGUCHI MINORU
Filed: 1988-02-09
Abstract: PURPOSE:To surely check credit membership numbers in response to various credit companies by checking the range and the check digit for a credit membership number inputted manually based on a company type-based table of each credit company. CONSTITUTION:The card menu numbers of various credit companies are displayed on a display device and a selected card menu number is inputted with registration for selection of a company type-based table. Then the possibility of a transaction is checked and a credit membership number range table is selected to check whether an input credit membership number is included within said table range or not. Then a corresponding check digit pattern table is selected based on the check digit pattern number of the selected company type- based table. When the selected pattern table is normal, the input credit membership number is decided as validity and credit register processing is allowed. Thus it is possible to surely check the credit membership numbers in accordance with various credit companies.

IPC: G03G15/20
Filed: 1995-02-16
Abstract: PURPOSE: To shorten a warming up time and to prevent the irregularity of the temperature on a narrow paper and the deterioration of the durability. CONSTITUTION: A heat roller 11 is formed of A6063 material aluminum whose quality class is T, the surface of the heat roller 11 is covered with fluororesin, the inside face of the heat roller 11 is painted black. Thus, the heat conductivity is increased, and also, the strength is increased. The covered heat roller 11 is fired at the firing temperature range of 350 to 380 deg.C and for a firing time range of 10 to 20 minutes, the painted heat roller 11 is dried at a temperature <=200 deg.C. Since the firing temperature is low and the firing time is short the strength of the heat roller 11 is prevented from being reduced due to annealing.

Title: Grinding machine
Inventor: FUJISHIMA SHIGERU
IPC: B24B49/00
Filed: 1987-02-12
Abstract: PURPOSE:To prevent a grindstone from being suddenly decelerated at the time of restarting as well as to prevent any breakdown accident, by installing a detecting device, detecting a revolving speed of the grindstone, and also installing a control unit for controlling the stone's revolving speed at the time of restarting on the basis of the stone speed information detected by this detecting means. CONSTITUTION:When restarting takes place after a power failure and an emergency stop are released, revolving speed of a grindstone 7 inertially rotating is detected by a revolution detector 10 on the basis of a speed detection signal S6 to be outputted out of a pulse generator 9. The revolution information of the grindstone 7 detected by this detector 10 is inputted into a computer control unit 1. Next, this control unit 1 gradually increases rotation of a wheel motor 4 from the inertia revolving speed of the grindstone 7 read by a signal S7, making it into the desired revolution, whereby sudden deceleration caused by wheel crack is prevented from occurring in a highly reliable manner.

Abstract: PURPOSE:To cause low speed continuous running of a truck for carriage by a method wherein two push drive mechanisms to propel a pair of members to be pushed on both sides mounted to each truck for carriage through respective pushers at a speed variable into a high and a low speed. CONSTITUTION:A pair of members 14a and 14b to be pushed on both sides are mounted to a truck 1 for carriage movable on a specified running route. Two push drive mechanisms 15A and 15B provided with pushers 16a and 16b positioned facing two members 14a and 14b to be pushed and drive means (servo motors) 18a and 18b capable of controlling a speed at which the pushers are propelled are mounted in juxtaposition in the push drive starting position of the truck 1 for carriage. In this constitution, a subsequent truck is forced to approach a preceding truck, running at a low speed, at a high speed as a pusher speed is controlled. After the trucks are brought into contact with each other without collision, the preceding and subsequent trucks are integrally pushed and driven at a low speed, and this constitution drives the trucks fed, in order, to push drive starting positions to be automatically and continuously pushed and driven at a constant speed.
