Title: Pulse oscillation type gas laser oscillator
Inventor: SHIMADA HIDEKI
IPC: H01S3/036
Filed: 1990-09-26
Abstract: PURPOSE:To increase the flow rate of a gas without deteriorating inflow efficiency to a main electrode of a laser gas even when the blasting surface of an air blower section is larger than the gas inflow surface of a discharge space, and to prevent the generation of arc discharge even when the pulse oscillation of a laser are repeated a large number of times by installing a guide plate introducing the laser gas extending over the gas inflow surface from the blasting surface. CONSTITUTION:Voltage is applied between a section between main electrodes 2a as a discharge space, a gas cooled by a cooling section 6 is blasted from an air blower section 5, and laser oscillation is conducted. Guide plates 3 are mounted toward the main electrodes 2a from the air blower section 5 for increasing the flow rate of the laser gas in the discharge space in order to prevent the generation of arc discharge at that time, thus accelerating the flow rate by the effect of a narrowed flow path. The increasing gas flow forms flow paths shown in the arrows through the discharge space, and enters the cooling section 6 again. Accordingly, the laser gas reaching sections except the discharge space is removed, and the flow rate of the gas is increased, thus repeating the pulse oscillation of a laser generating no arc discharge a large number of times.

Title: Fine cold cathode, its manufacture and field emitter array
Inventor: KOBAYASHI TAKESHI
IPC: H01J9/02
Filed: 1994-09-21
Abstract: PURPOSE: To narrow a space between a cold cathode electron source and a gate electrode so as to attain improving a current-voltage characteristic, by forming a cone part with a sharp point end as the cold cathode electron source on a substrate, and forming the gate electrode through a thermal oxidation film in a peripheral side surface of the cone part. CONSTITUTION: Etching is applied to an insulating film 20 formed in a silicon substrate 10, to form an insulating film pattern 21. Isotropic etching is selectively applied to the substrate 10, to form a cone part 30 under the insulating film pattern 21. Next by thermal oxidation treatment, the first thermal oxidation film 40 is formed in surfaces of the substrate 10 and the cone part 30. This first thermal oxidation film 40 is removed. Thermal oxidation treatment is applied to the substrate 10 formed with the cone 30, to form the second thermal oxidation film 70 (SiO2 film). Next in a surface of the second thermal oxidation film 70, a gate electrode film 60 is formed. Etching is selectively applied to only the gate electrode film 60, and after a gate electrode 61 is formed, the second thermal oxidation film 70, coating a point end of the cone part 30, is removed.

Title: Door device for optical driver
Inventor: RI EISHIYAKU
IPC: G11B33/02
Filed: 1996-09-26
Abstract: PROBLEM TO BE SOLVED: To simplify the structure and to interrupt entering of dust by providing an inside door opening only at a caddy take-out time and an outside door hinge fixed to it and opening in the one direction only at an insertion time. SOLUTION: When the caddy 10 is pushed into the port of the outside door 12, the inside door 13 turns around a pin 13b to open inside. At this time, since the upper end part of the outside door 12 is prevented by a cover 11, the door 12 isn't pressed in the insertion direction of the caddy, and only the inside door 13 is opened. Succedingly, when the caddy 10 is ended to be inserted, the inside door 13 is closed by force of a torsion spring. When the caddy 10 is taken out, the caddy 10 is transferred to the door, and when the caddy 10 presses the inside door 13 by the transfer force, the inside door 13 presses the outside door 12, and the outside door 12 turns around a hinge position to open in the take-out direction. When the caddy 10 is taken out, the outside door 13 is closed by the force of the torsion spring 14 of the pin 13a of the inside door 13.  Thus, the structure is simplified, and the entering of dust is interrupted, and the life of a driver is prolonged, and the reliability is improved.

Title: Crusher
Inventor: IWANISHI YOSHIHIDE
IPC: B02C18/00
Filed: 1998-09-09
Abstract: PROBLEM TO BE SOLVED: To prevent the reduction of crushing efficiency due to the friction heat generating at the time of crushing. SOLUTION: Air (cold air) injection holes 11 are formed in both side faces 1s, 1s of a main body near the respective rotary axes 2 and at the time of operation, air is constantly jetted to cool the rotary axes 2 and rotary blades 3. Due to the jetting pressure of the air, un-crushed large wastes gather near the center of the rotary axes 2 and small particles of crushed wastes are stirred in the surrounding of the rotary balades 3 and, therefore, more frequently brought into contact with the rotary blades 3 and as a result the crushing efficiency is heightened.  A communication route 16 surrounding the circumference of a bearing 4 is formed in the inside of the side wall 1w of the main body 1 and cooling water is injected through an injection hole communicated with the route 16, discharged out of a discharge hole and again circulated to a circulation route communicated in the injection hole to cool the bearing 4. An injection hole 12 for liquefied nitrogen is formed in a cover for the front face of the main body and in the case, further efficient cooling work is required, liquefied nitrogen is properly jetted to cool the rotary blades 3.

IPC: H01S5/0625
Filed: 1987-10-09
Abstract: PURPOSE:To vary the oscillation wavelength of a semiconductor laser device of independently irrespective of a temperature and an optical output by feeding injecting currents of controlled values to curved parts having different curvatures for forming an optical guide path. CONSTITUTION:Regions are patterned with an Si3N4 film or the like by at least first and second curved parts having different curvatures, i.e., a curved part 51a curved in radius R1 of curvature to a positive side and a curved part 51b curved in radius R2 of curvature to a negative side, and divided to first and second regions. With the Si3N4 film as a mask an impurity, such as Zn is diffused at approx. 650 deg.C, then the Zn of the impurity diffusion source is removed, heat treated at a high temperature, thereby partly converting the regions to P-type. Since the refractive index of a narrow P<+> type region 32 becomes higher than those of both sides, a light is guided to the region 32, electrons are implanted by a forward current from the N-type side to the region 32, thereby irradiating a light, and generating an inversion distribution by increasing its current density, the light is amplified, and both reflecting faces are oscillated.

Title: Magnetic recording medium
Inventor: SHINOHARA KOICHI
IPC: G11B5/66
Filed: 1989-09-29
Abstract: PURPOSE:To obtain a magnetic recording medium having excellent durability and corrosion resistance at high production speed by incorporating nitrogen by 0.3 - 2atm.% into an iron film formed by oblique deposition on a polymer film. CONSTITUTION:Nitrogen is incorporated by 0.3 - 2atm.% into an iron film 2 formed by oblique deposition on a polymer film 1. For example, when iron vapor is deposited by an electron beam deposition method on a traveling polymer film 1 with changing the minimum incident angle of the beam from right angle, nitrogen atoms are made to irradiate the film at the same time, or nitrogen gas is introduced to incorporate nitrogen into the film. By this method, crystallinity of iron can be improved and defects are reduced in the obtd. film, which improves long-term stability and characteristics as the magnetic recording layer. Particularly, the recording layer is suitable for high production speed since the process needs no reaction.
