Title: Video tape recorder
Inventor: YOSHIZUMI KIMIO
IPC: G11B15/48
Filed: 1984-05-11
Abstract: PURPOSE:To cease speedily the fluctuation of a speed error voltage during switching from high-speed operation to low-speed operation by suppressing a rise in speed voltage above a set reference voltage through a control system. CONSTITUTION:When a signal for constant-speed reproducing operation is supplied to the system controller of VTR during fast searching operation, a brake voltage is applied from a terminal 10 to a synthesizing circuit 7 and a negative impulsive reverse signal is supplied from a terminal 12 to a driving circuit 9. Then, if the fluctuation of the output voltage of a sample-hold circuit 6 begins to increase at the switching point of frequency division ratios of a frequency divider 4, a switch 14 is turned on with the output of a comparator 13 once the voltage exceeds the reference voltage E0 and the brake voltage turned off only during the on period of the switch. Consequently, the speed error voltage from the circuit 6 is limited to the reference voltage E0.

Title: Circuit for detecting position of bonding surface
Inventor: SUEMATSU MUTSUMI
IPC: H01L21/603
Filed: 1987-04-20
Abstract: PURPOSE:To make it possible to detect a position highly accurately with a simple, low-cost constitution even if the descending speed of a capillary is high and vibration occurs, by detecting a bonding surface the comparison of a judged value which is obtained from a reference level and the detected output of the speed of a motor. CONSTITUTION:When a sway bracket 3 is moved until a capillary 4 is brought into sure contact with a bonding surface, the voltage value of a speed signal VI decreases quickly. The speed signal VI becomes smaller than a judged value VJ. A detected signal OT at an 'H' level is outputted to a control part 35. At this time, the position of the capillary 4 is recognized as the position of the bonding surface. A signal PC from a counter 37 is inputted. The height of the bonding surface at this time is computed according to the number of pulses indicated by the signal PC. A driving signal MS for moving the sway bracket 3 by a specified amount in this state is outputted to a motor 30. Thus, the capillary is pushed to the bonding surface with a pushing force corresponding to a sway. As a result, wire bonding is always performed at the constant pushing force.

Title: Detecting method for defect of insulating film
Inventor: NISHIOKA SUNAO
IPC: H01L21/66
Filed: 1979-07-25
Abstract: PURPOSE: To highly sensitively detect a micro-sized defect of an insulating film by setting the focus of an optical microscope in the vicinity of the boundary between a nematic liquid crystal film and a glass plate coated with a transparent conductive film in order to measure the dynamic scattering effect.  
     CONSTITUTION: The focus C of an optical microscope 12 is set on the boundary between a nematic liquid crystal film 4 and a glass plate 5 coated with a transparent conductive film. Thus, the light quantity of a step portion-scattered light 14 entering the microscope 12 decreases, and consequently the image by the scattered light 14 is not focued. However, a dynamic scattering effect is produced in the nematic liquid crystal film 4 as far as the portion thereof contacting with the glass plate 5, and the geometric range in which the dynamic scattering effect is exerted maximizes at the portion contacting with the glass plate 5. Consequently, the light quantity ratio of a defective portion-scattered light 13 to the step portion-scattered light 14 entering the microscope 12 increases, and so the images by both scattered lights are clearly contrasted with each other. This permits errors in the defect detection to disappear, and accordingly, an image analyzing means can perform an accurate detection.

Abstract: PURPOSE:To increase the charging speed of fuel into a metering chamber in a fuel metering device and to prevent air from being accumulated, by providing a fuel outlet port for circulating fuel through the fuel metering device, at a position above a fuel inlet in opposite to the inlet port. CONSTITUTION:A fuel metering device 20 comprising a linear motor 54 for adjusting the position of an adjuster 49 so that the volume of a metering chamber 39 corresponds to a fuel injection amount, opens a fuel inlet 40 and a fuel outlet 41 while closing a fuel discharge outlet 44 and the opening 50a of a cylindrical member 50, and therefore, fuel is circulated through a fuel system by way of the fuel metering chamber 39. Further, when a solenoid valve 59 is opened during fuel injection timing, pressurized air flows into an air chamber 56 to depress an adjusting rod 51 so that two valves 42, 43 are closed to feed fuel under pressure from the discharge outlet port 44. In this arrangement, since the fuel outlet port 41 is arranged at a position above the inlet 40 in opposite to the latter, the flowing condition of fuel in a metering chamber 39 is satisfactory, and therefore, it is possible to rapidly charge fuel with no air accumulation. Accordingly, it is possible to precisely supply a predetermined amount of fuel into the engine.

Title: Production of thick steel plate having less surface defect in corner part
Inventor: KONUMA YUKIO
IPC: B21B1/38
Filed: 1985-05-07
Abstract: PURPOSE:To improve the yield of material by forming roundness to the corner parts at the front and rear ends of a steel slab then subjecting the slab to heating and rolling. CONSTITUTION:About 10-50mm roundness is formed via a flux to the corner parts 2 of the steel slab 1. The slab 1 rounded at the corner parts 2 is heated to a prescribed temp. in a heating furnace and is conveyed to a rolling mill, by which the slab is rolled. Since the corner parts 2 of the slab 1 are rounded, the temp. decrease of the parts 2 in the mid-way of conveyance is relieved and the temp. difference between the flat part and corner parts 2 of the slab 1 is decreased. The surface defects generated in the corner parts 2 during rolling are thus considerably decreased. The cutting margins at the front and rear ends of the thick steel plate are thereby decreased and therefore the yield of the material increases by about 0.2%.
