Title: Magnetic head
Inventor: KANAMARU TOSHIMI
IPC: G11B5/23
Filed: 1982-07-31
Abstract: PURPOSE:To obtain extremely stable magnetic exhange characteristics, by joining plural plate-shaped magnetic bodies together, forming a cut at the outer circumference part of at least one plate-shaped magnetic body, and expanding the cut and arranging an expanding member for pressing front gap surfaces against each other. CONSTITUTION:Core blocks 10 and 11 having tapered cuts 18 and 19 are joined together by laser welding in a usual way. The thermal expansion coefficient of the expanding member 20 inserted in the cuts 18 and 19 is less than those of the core blocks 10 and 11 in a heat treatment, so the expanding member 20 is held in the cuts 18 and 19 in a tight fit state at room temperature and also expands the cuts 18 and 19 to press the front gap surfaces 8 and 9 against each other, so that gap length precision and track abutting precision are much more stabler than usual even during an actual contact run on a tape.

Title: Controlling of electric vehicle
Inventor: YOMO SUSUMU
IPC: H02P7/298
Filed: 1977-11-08
Abstract: PURPOSE: To prevent the jumping of motor current, by detecting that the ratio of the motor current to a limited current level falls to a predetermined value after the turn- on ratio of chopper has reached the maximum value and by reducing the field excitation of the motor.  
     CONSTITUTION: The motor current, which is controlld by a current pattern instruction applied from a load responsible unit 17, can be varied by the turn-on ratio of the chopper 14. When the turn-on ratio has reached the miximum value, it is maintained at this value. Then, the motor current decreases on a characteristic curve. When the motor current has reached a predetermined ratio to the limited current level, a low field excitation switch 11 is turned on by a central processor 20 made of a multiplexer. Therefore, the drop in the motor current can be reduced.

Abstract: PURPOSE:To prevent luminance lowering and a color irregularity in the periphery area of a panel by forming a panel not to have a skirt part and binding the periphery part of the panel and a funnel. CONSTITUTION:A panel 1 is formed to have a specific curvature of inside plane and not to have a skirt part.

Abstract: PROBLEM TO BE SOLVED: To perform smooth automatic running switching by servicing an elevator to dedicated running car calling with a load detecting means for detecting a car load and releasing dedicated running with the passage of a specified time after the detection of a car load. SOLUTION: When dedicated running is performed by operating a dedicated running switching switch SW1 installed in a car C operation board OB, any one of car call buttons 51 to 53 is operated after a user switches to dedicated running, and by operating a door closing button CL, an elevator is started to go to a target floor. The car position of the elevator reaches the same floor as that of the car calling button operator, i.e., the target floor, a door is opened and baggage or the like is carried out from the elevator. When all carrying-out work is completed, no load remains in the car, it is returned to automatic running with the passage of a specified limited time, and service is provided to a user waiting on the other hall. If a specified time after the detection of no loads is about 10 to 15 sec., wasteful time until returning to automatic running is reduced.

Title: Thermal recorder
Inventor: KAMATA MASANORI

Filed: 1987-05-29
Abstract: PURPOSE:To prevent missing of dots from occurring in recorded images and record high quality images, by providing auxiliary heat generating resistors having a resistance larger than that of recording heat generating resistors at positions slightly on the vertically outer sides of both ends of an array of the recording heat generating resistors. CONSTITUTION:The resistance of auxiliary heat generating resistors R0 and Rm+1 is set to be larger than that of recording heat generating resistors R1-Rm so that when the same voltage as a voltage applied to the resistors R1-Rm at the time of recording is applied to the resistors R0 and Rm+1 for the same duration as that for recording, the quantities of heat generated by the resistors R0 and Rm+1 are so small as not to produce a recording action on a thermal recording paper. When the resistor R1 of the first dot at an end is energized, thc auxiliary resistor R0 is also energized through an AND gate A0 and a driver D0. The quantity of heat generated by the resistor R0 thus energized is so small that recording in black does not take place, but the heat ensures that the characteristics of diffusion of heat from the first dot R1 is substantially equal to those for other, intermediate dots. Similarly, when the resistor Rm of the m-th dot at an end is energized, the auxiliary resistor Rm+1 is also energized. Thus, the heat diffusion conditions for the end dots R1 and Rm are substantially the same as those for the intermediate dots R2-Rm-1.
