IPC: H01L29/78
Filed: 1988-08-03
Abstract: PURPOSE:To dispense with a resist coating process for the formation of a resist pattern and a photoetching process by a method wherein an oxide film left on a high-impurity region, which is formed for coming into contact to a source electrode, is used as a mask at the time of ion-implantation for forming source regions in addition to a gate oxide film and gate electrode patterns. CONSTITUTION:A second conductivity type high-impurity concentration region 21 is formed in the surface layer of a first conductivity type drain region (an Si substrate) 1 and thereafter, part of a surface oxide film 41 is made to remain only on a prescribed region of the region 21 and the rest of the film 41 is removed. Then, a second conductivity type channel region 22 is formed. Then, after a gate oxide film and a gate electrode layer are laminated, a patterning of gate electrodes 5 and a gate oxide film 4 under the electrodes 5 is performed leaving said remaining oxide film 41. Then, an ion-implantation for forming first conductivity type source regions 3 is performed using the electrodes 5, the gate oxide film pattern 4 and the remaining oxide film 41 as masks. After that, for example, the surface is covered with a PSG layer 9, a contact hole is formed in a photoetching process and a source electrode 6 is formed.

Title: LIGHT SOURCE DEVICE PROVIDED WITH GaN-BASED SEMICONDUCTOR LIGHT EMITTING ELEMENT AND REMOVAL METHOD FOR STRAY LIGHT
Inventor: HAYAKAWA TOSHIRO
IPC: H01S5/343
Filed: 1999-07-08
Abstract: PROBLEM TO BE SOLVED: To prevent a change in the shape of a light spot due to a change in the driving current of a GaN-based semiconductor light emitting element by forming a spatial filter by which stray light as a specific output under the maximum output of the GaN-based semiconductor light emitting element is removed from light which is emitted from the light emitting element. SOLUTION: From light which is emitted from a GaN-based semiconductor laser 20, stray light at 20% or lower of the total output under the maximum output of the semiconductor laser is removed by a spatial filter which is constituted of a slit plate 23. For example, stray light which is generated mainly in a low-current region which does not reach a laser oscillation threshold value is removed by the slit plate 23. Consequently, it is possible to prevent a change in the shape of a light spot caused by the generation of the stray light. At this time, this light source device which is provided with the GaN-based semiconductor laser can control a quantity of recording light accurately, and it is suitable for a printing field, a photographic field and a medical image field in which a high-grade gradation exposure is required.

Title: Electric terminal extending through sealed container
Inventor: MOCHIZUKI MITSUAKI
IPC: H01R9/16
Filed: 1988-08-03
Abstract: PURPOSE:To prevent cracks from occurring in an airtightly sealed portion by extending an MI cable, having an aluminum sheath whose both ends or one end is airtightly sealed and insulated with powder member, through a sealed aluminum container and welding therebetween. CONSTITUTION:An MI cable 3, in which ceramics powder member is used as an insulator for an aluminum sheath, is extended through a vacuum sealed container 1 formed of aluminum, and the container 1 and the cable 3 are welded together airtightly by a laser. The difference between the thermal expansion coefficients occurring at that time is absorbed by the powder member as the insulator, because the thermal expansion coefficients are nearly equal, so that cracks will never produced in the airtightly sealed portion. Further, airtight sealing is effected at both ends or one end of the cable 3 by ceramics which chemically reacts with the insulating powder member so that the stress due to the expansion of the container 1 is not transmitted hence cracks will never occur. Thus, the cracks in the airtightly sealed portion due to the difference between the thermal expansion of the container and the cable is prevented from occurring.

Title: Clock phase control system
Inventor: YOSHIMURA TATSURO
IPC: G06F1/04
Filed: 1985-09-04
Abstract: PURPOSE:To minimize the number of the external lead-out terminals used for phase control and to select rationally the terminals for control of phase, by making use of a scan-in/out means. CONSTITUTION:A delay part 1 delivers selectively an input clock as a delayed clock signal of maximum m(=2<n>) steps in accordance with the n-bit selection signal. While a delay part 2 delivers selectively the input clock as a delayed clock signal of minimum 1/2<p> steps compared with the minimum step width of the part 1 in accordance with the p-bit selection signal. The delay parts 1, 2 are connected cascadedly. Thus a delayed clock having optional 1/2<p> steps against the input clock signal can be delivered just by setting the selection data to (n+p) pieces of scan-in/out latch circuits 3a-3d in order to obtain optional delayed clock signals. In such a way, the number of external lead-out terminals is minimized.

IPC: G03B27/50
Filed: 1987-08-04
Abstract: PURPOSE:To miniaturize a lens and to reduce the quantity of an eccentricity so as to hold by cutting off a lens and its holding frame in a horizontal direction within at least an open angle 180 deg. on an upper side which is the longitudinal direction of a slit. CONSTITUTION:In case of considering the miniaturization of a slit scanning optical system, the sizes of the respective optical members constituting the optical system and the width of image formation luminous flux should be considered. In case of the slit scanning, the width direction of a slit of the effective range of the lens is decided from the mechanical width of the slit. Then the lens 22 having a diameter d1 is horizontally cut off only on the upper side from the optical axis of the lens. If the lens is assembled with the side where peripheral part remains by a lens barrel 21 having a diameter d2 while adjusting the focus of the lens at the time of assembling the lens, it can be settled within the maximum quantity of eccentricity in case of a round lens at most. Thus, the lens can be miniaturized and also it can be held without causing the error of eccentricity.

Abstract: PURPOSE:To aim at preventing a driving feeling from worsening, by installing a capacity selector mechanism for opening of closing a first bypass passage and a control valve, gradually closing all passages by means of dynamic pressure of reflux gas inside a second bypass passage with closure of this passage both inside a discharge chamber. CONSTITUTION:Compressed high temperature discharge gas is fed, with pressure, to a back pressure chamber 57 via a high pressure pipe 60, while a spool 47 is moved to a regular closing position together with a discharge valve 44 and a valve guard 46, closing a first bypass passage 56. Therefore, the whole quantity of gas discharged to the discharge chamber 22 passes through a second passage 65 alone and is made to flow back to a swash plate chamber 8 whereby a control valve 67 tries to be moved in a direction to close the passage 65 by dint of dynamic pressure of reflux gas, but since the intake of pressure compensating for negative pressure in a back pressure chamber 69 is throttled by a pressure intake hole 70, its motion is regulated so as to come sluggish, and a gas quantity is gradually increased till the control valve 67 comes to 100% operation having closed the passage 65 completely so that with this increase, engine load also slowly goes up, therefore a shock is effectively relievable.
