Filed: 1998-02-26
Abstract: PROBLEM TO BE SOLVED: To facilitate production of an iron head which is hardly breakable and is usable for a long period by installing weight members to a part of the front surface of a sole wall part forming the lower edge of a recessed part or the entire part thereof. SOLUTION: The iron head has a head body A having the recessed part 1 on the rear surface side of the head. The weight members 9, 9 are installed to a part of the rear surface 5 of the sole wall part 3 forming the lower edge of the recessed part 1. The iron head is designed to a low centroid while the sweat area is expanded. In addition, the weight members 9, 9 are disposed on the front surface 5 side of the sole wall part 3, by which these members are made contactless from a ground contact surface S. Since the iron head does not receive external force directly from the ground contact surface S, the desorption from the fitting recessed parts 8, 8 does not arise any more. Further, there is no worry about the damage by the wear of the weight members 9, 9 and, therefore, the degree of freedom in selecting metallic materials constituting the weight members 9 is widened.

Abstract: PURPOSE:To facilitate the grindstone replacing operation and improve the efficiency in grinding process by separately installing two kinds of grindstones onto the shafts supported rotatably at the both edges of a rotary plate and departing one grindstone when the other is at the grinding position on a cutter by the revolution of the rotary plate. CONSTITUTION:When a motor is revolved normally in rough finishing grinding, a rotary plate 12 turns clockwise to bring a rough finishing grindstone 18 close to a ground cutter W, drawing a circular locus (r), and at the same time, a finishing grindstone 18a is departed over the cutter W, and intermediate gears 27 and 27a revolve fixed gears 26 and 26a reversely. Then, the counterclockwise revolution in equal revolution angle to that of the rotary plate 12 is transmitted to a shaft, and since the shaft does not revolve relatively, and elevation frames 17 and 17a maintain vertical posture, the axis lines of the rough and finishing grindstones 18 and 18a are not changed. When revolution is suspended, the grindstone 18 corresponds to the ground surface of the cutter W at the center of a cutter installation board 4, and grinding is carried-out by controlling the transverse transfer by a handle 3, after adjusting the vertical position by an elevation screw 16. Also in finishing grinding, similar operation is carried-out.

Title: Light quantity adjusting method/device
Inventor: TERADA HIROTOSHI
IPC: H01S3/10
Filed: 1998-03-16
Abstract: PROBLEM TO BE SOLVED: To eliminate the adjustment of the optical axis of outgoing light and to be able to continuously change the light quantity. SOLUTION: In the device 10, same polarizing beam splitters 14 and 15 different in transmission quantity corresponding to polarization component are symmetrically arranged against a plane orthogonal to the rotary axis of an inner lens barrel 12 arranged in an outer lens barrel 11 so that it can freely rotate by inclining them at an angle θ by using a holding member 13. When an optical axis makes the linear polarizing light from a laser light source 1 enter so that it may be matched with the rotary axis of the inner lens barrel 12 and the inner lens barrel 12 is rotated to a desired position, the rate of the polarization components of laser light beams which are made incident on the polarizing beam splitters 14 and 15 changes in accordance with a rotary angle.  Thus, the light quantity of outgoing light continuously changes and the optical axis shift and the angle blurring of the beam splitters 14 and 15 are canceled by each other. Consequently, an outgoing optical axis is always matched with an incident optical axis.

IPC: H01L29/78
Filed: 1981-04-29
Abstract: PURPOSE:To obtain a finer, higher density device by a method wherein source and drain electrode openings are produced self-alignedly with a gate electrode. CONSTITUTION:The upper surface of an MOSFET located on a p type Si substrate 1 is covered with a CVD Si3N4 film 9 and a resist 10 is applied thereto in a rotation application, which results in the formation of a thin cost on a gate electrode 4. The entire surface is exposed without a mask and then subjected to firing to remove the resist thin film for the exposure of the Si3N4 film 9. With the resist 10 acting as a mask, plasma etching is performed in CF+O2 to remove the Si3N4 film 9 from the upper surface and the sides of the gate electrode 4. The resist 10 is removed and the remaining Si3N4 9 acts as a mask in the formation of an approximately 4,000Angstrom thick SiO2 film 8 on the electrode 4. Next, the Si3N4 film 9 and an SiO2 film 7 are plasma etched into openings 11 and 12. No photomasks are used after the formation of the gate electrode 4 and positioning relative to the electrode 4 is all determined by self-alignment. Accordingly, need for positioning allowances is eliminated and a finer, higher density device is manufactured.

Abstract: PURPOSE:To ensure the white balance with no error and over a considerably wide range of the intensity of the input light, by giving the control to the channel gain via the control signal which is obtained through the conversion with the ratio of the illumination light sensor output used for the logarithm ratio. CONSTITUTION:Conversion output E1 and E2 are applied to voltage comparators 11 and 12 from photoelectric conversion parts 1 and 2 possessing the spectral sensitivity characteristics which corresponds to R and G channels of each camera. On the other hand, signal E0 featuring the reduction in the exponent function way is applied to comparators 11 and 12 from exponent function signal producing part 10. Thus pulse duration modulated PWM signal of negative directional amplitude E0-E1 is  obtained from comparator 11; while the positive directional PWM signal is obtained  from comparator 12 each. These two signals are then supplied to AND circuit 13,  and the PWM signal proportional to the value which received the logarithm conversion of the ratio between output E1 and E2 is obtained from circuit 13. This PWM  signal is sent to time-voltage converting part 14 to be converted into the voltage,  and then applied to gain control amplifier 15. As a result, both the R and G  channel outputs of the camera can always be held constant.
