Abstract: PURPOSE:To improve the cooling effect of a resistor by driving a fan-driving motor in response to the quantity of a current of the resistor during dynamic braking and by means of a constant-voltage supply source when the current do not flow through the resistor. CONSTITUTION:When the state of dynamic braking is brought, a line breaker 11 is closed, and a current I corresponding to a travel speed of a vehicle flows through a resistor 12, thus generating braking force. DC voltage Vr proportional to the current I is generated simultaneously in a center tap 12a for the resistor 12. When the DC voltage Vr exceeds a voltage V4 through a rectifying circuit 16 from a quaternary winding 6, it is applied as an input voltage Vi to an inverter 19. Accordingly, heat generated by the resistor 12 during dynamic braking is cooled by the revolution of a fan 14 corresponding to a calorific value of the heat, and the remain heat of the resistor 12 is removed by the fan 14 driven at the constant voltage V4 after the completion of braking.

Title: Substrate for thermal head and preparation thereof
Inventor: NISHIOKA YOICHI
IPC: B41J2/335
Filed: 1988-08-31
Abstract: PURPOSE:To form a thermal head having a heat insulating layer showing high heat conductivity and high mechanical strength and imparting good printing quality by constituting the heat insulating layer on an insulating substrate of ZrO2-SiO2 glass wherein voids having a specific pore size are distributed uniformly. CONSTITUTION:A substrate for a thermal head is constituted by providing a heat insulating layer 2 composed of ZrO2-SiO2 glass or TiO2-SiO2 glass wherein voids having a pore size of 1-100nm are uniformly distributed on an insulating substrate 1. Since the heat insulating layer 2 has voids, the heat conductivity thereof is low and, even when the heat insulating layer is made thin corresponding thereto, sufficiently high heat insulating properties can be imparted. Therefore, the radiation speed of a heating unit can be increased while the enhancement of heat efficiency is achieved and power consumption can be reduced low and a printing speed can be increased. Since the heat insulating layer is constituted of oxide, this substrate has properties excellent in heat resistance and alkali resistance. Further, the heat insulating layer uniform in void distribution can be formed and a thermal head imparting good printing quality can be formed.

Abstract: PURPOSE:To achieve film winding/rewinding and shutter charge by means of motor drive by providing a sun gear, a charge gear, a rewinding gear, a winding gear, first and second planetary gears, and means for preventing unnecessary mesh of each. CONSTITUTION:At the time of winding, a motor pinion 20 normally rotates the sun gear 23 clockwise via a gear train; levers 25 and 26 swing in the same direction and stop; the second planetary gear 30 and a gear 35 mesh together; consequently the second planetary gear 28 releases the mesh of the winding gear 32a. A gear 37a turns to press a shutter lever 14a, and a cam 37b makes one rotation to stop the motor. At the time of rewinding, the motor pinion reversely rotates; the cam 37b also reversely rotates; at the time when it rotates about 24 deg., the motor stops and is switched to normal rotation. The first planetary lever 25 can not swing counterclockwise, and the planetary gear 28 and the winding gear 32a can not mesh together. On the other hand, when the lever 26 swings counterclockwise, gears 30 and 36 mesh, and accordingly a rewinding mechanism is actuated. In this mechanism, winding and rewinding can be carried out by means of a common motor, and shutter charge can be performed.

Filed: 1988-09-05
Abstract: PURPOSE:To stabilize an air-fuel ratio after warming up run by updating, by a learning means, a learning value per temperature region, which is provided in every temperature region of an engine, so that a torque fluctuating rate becomes a prescribed value, and adjusting the air-fuel ratio in response to the above learning value per temperature region by an air-fuel ratio adjusting means, when an engine is in the state of warming up run. CONSTITUTION:The torque fluctuating rate of an engine is calculated by a torque fluctuating rate calculating means, and it is discriminated by a warming up condition discriminating means whether the engine is in a warming up condition or not. As a result, a learning value Wi per temperature region, which is provided in every temperature region of the engine, is updated by a learning means so that the torque fluctuating rate becomes a prescribed value. Further, when the engine is in the warming up condition, an air-fuel ratio of the engine is adjusted by an air-fuel ratio adjusting means, in response to the learning value Wi per temperature region. Namely, during warming up, the learning value per temperature region is updated, therefore, since an air-fuel ratio lean limit control is operated in response to the temperature of the engine, the air-fuel ratio after warming up is stabilized without influencing a learning per load region after warming up, so that emission of HC, CO, NOx, fuel consumption and the like can be prevented from worsening.

IPC: G11B5/133
Filed: 1986-09-18
Abstract: PURPOSE:To improve reproduction output and wear resistance at a low cost by using a ferrite single crystal contg. Fe2O3 at a specific value for a core material and providing a magnetic path face at about the (113) face of the single crystal and tape sliding face at the (110) face. CONSTITUTION:The cores 1a, 1b are formed by using the ferrite single crystal contg. about >=54mol% Fe2O3. The cores are so formed that the crystal face of the magnetic path face 5 of the cores is about the (113) face of the ferrite single crystal, the crystal face of the sliding contact face 6 with a tape is the (110) face and the crystal faces at the butt surfaces of the cores 1a, 1b are the (332) face. The head saturation at the time of recording at a low frequency is relieved and the magnetic permeability of the cores in a high-frequency region is improved by which the reproduction output is improved when such head and an ordinary head are comparatively measured. The wear is less than with the head having the sliding contact face 6 at the (332) face. The reproduction output and wear resistance are improved at the low cost by producing the head while taking the crystal face into consideration.
