Title: Bias circuit
Inventor: NAGASE KATSUTERU
IPC: H03B5/04
Filed: 1988-08-22
Abstract: PURPOSE:To keep a source terminal voltage and current constant and to make an RF output of an oscillation circuit constant by controlling the circuit so that negative feedback is applied to a field effect transistor(TR). CONSTITUTION:When a current of a source terminal 2C of a field effect transistor(TR) 2 is increased, a terminal voltage across a 2nd resistor 7 rises, a base-emitter voltage of a control TR 10 rises and a collector current of the TR 10 is increased. When the collector current is increased, a terminal voltage across a 3rd resistor 8 rises and the gate-source voltage of the TR 2 is biased deep, the current of the terminal 2c is reduced to form a negative feedback circuit. Even if the voltage current of the terminal 2C is going to be fluctuated, the voltage current of the terminal 2C is kept constant. Thus, the RF output of the oscillation circuit is kept constant.

Title: Optical lens for large output laser
Inventor: EHATA KEIJI
IPC: B23K26/064
Filed: 1987-08-20
Abstract: PURPOSE:To reduce the energy load of a laser light and to enable the use for long term by forming at the center part a through hole smaller than the diameter of a laser light incident on the optical lens for laser. CONSTITUTION:The through hole 6 formed at the center of a lens 5 is of the diameter small enough compared with the diameter of a laser light 7. Therefore, the light at the center having higher energy is not directly absorbed by the lens 5. Only the lower energy laser light of the environmental part is condensed by passing through the lens 5. Also, due to the laser light of the center part passing through the hole 6 linearly propagating as it is, it is collected to the converging part of the laser light. Consequently, the laser light can be converged in the necessary diameter by the lens 5 by reducing the size of the through hole 6 move than the diameter of the laser light.

Filed: 1986-09-05
Abstract: PURPOSE:To prevent the contamination of the mask substrate and pellicle themselves by using a member consisting of only the material which does not sublimate and evaporate at and under an ordinary temp. and atmospheric pressure to constitute the pellicle. CONSTITUTION:A frame 3 of the pellicle 1 is formed of a metal such as aluminum or stainless steel and a transparent pellicle film 2 of nitrocellulose, etc., is provided on the frame 3.

Title: Orthogonal frequency division multiplex signal transmission method, transmitter and receiver
Inventor: HAYASHIYAMA TAKUMI
IPC: H04J11/00
Filed: 1999-07-23
Abstract: PROBLEM TO BE SOLVED: To reduce the circuit scale of a puncture coding circuit and a de- puncture conversion circuit in the case of a high coding rate when using a puncture code. SOLUTION: A trellis coding circuit 62 intermittently reads data from a large capacity memory in the unit of bytes, applies intermittent coding to intermittent data in the unit of bytes and stores the coded data to an FIFO memory 63 by one data frame. The memory 63 reads intermittent data in the unit of bits by each data frame. Since the FIFO memory 63 converts input data to a puncture coding circuit 64 into intermittent data in the unit of bits by each data frame, the puncture coding circuit 64 can conduct processing in the unit of bits and the circuit scale can be reduced. The puncture coding circuit 64 deletes data according to a prescribed rule from a convolution code at a single coding rate to generate the code at the optional coding rate.

Filed: 1985-09-24
Abstract: PURPOSE:To improve the rotating efficiency of a wind mill by forming an inner wind tunnel structure into a double wind tunnel structure so as to allow each of two air flows to be joined together for blowing off stagnation generated behind the wind mill. CONSTITUTION:An inner wind tunnel structure 6 is provided rotatably within an inner circumference of an outer wind tunnel structure 1 so as to form No.1 inner wind tunnel 10 and No.2 inner wind tunnel 12.

Title: Method for forming carbon film on surface of magnetic recording medium
Inventor: OKUMURA YOSHINOBU
IPC: G11B5/84
Filed: 1989-08-11
Abstract: PURPOSE:To improve the adhesive strength of the liquid lubricating film to the solid lubricating film, and to stabilize the function of a protective lubricating film between a magnetic film and a magnetic head by applying a liquid lubricant on the surface of a solid lubricating film which covers the metal magnetic film on a nonmagnetic supporting body, and then irradiating the coating film with UV ray. CONSTITUTION:The liquid lubricant is applied on the surface of solid lubricating film which covers the metal magnetic film on a nonmagnetic supporting body, and then irradiated with UV ray. The UV ray excites the functional groups in the coating film of the liquid lubricant on the solid lubricating film. By this method, the liquid lubricating film applied on the solid lubricating film can be made to adhere firmly on the solid lubricating film. Thus, interaction between the solid lubricating film and liquid lubricating film gives an effect of stabilizing the protective lubricating function to the magnetic film and a magnetic head.

Title: Method for diffusing zn into compound semiconductor of inp system
Inventor: KAGAWA SHUZO
IPC: H01L21/22
Filed: 1984-10-05
Abstract: PURPOSE:To enable very stable and excellently reproducible diffusion having as a source Zn3P2 which is a product from thermal decomposition of ZnP2, by locally heating the ZnP2 portion after vacuum sealing to cause it to decompose, allowing it to condensate on the inner wall of a quartz tube, and then diffusing it. CONSTITUTION:Weighted ZnP2 5 is placed in a quartz tube 1 at one end thereof, and a InP wafer 3 is placed in the center of the tube 1. After vacuum sealing in a vacuum below 1X10<-6> torr, only the ZnP2 5 portion is heated with a burner 7 to decompose and allowed to condensate on a cooling portion 6. Thereafter, it is placed in a heat treatment furnace of 500 deg.C for, e.g., 20 minutes, thereby forming P-type layer which is about 2mum deep. At this time, if the amount of ZnP2 to be enclosed exceeds 0.2mg/cm<3>, the decomposition product of ZnP2 does not become Zn3P2, and the diffusion depth becomes shallow. Further, if the amount is less than 0.005mg/cm<3>, the saturated vapor pressure at 500 deg.C is not reached, thus providing inferior reproductivity of diffusion depth. Accordingly, if the amount of ZnP2 is set within the range of 0.005mg/cm<3>-0.2mg/cm<3>, ZnP2 decomposes into Zn3P2 and P4 and becomes easy to vaporize, exhibiting very good reproductivity.
