Title: Granulating method and device
Inventor: KATSUKI YUKIO
IPC: B29B9/06
Filed: 1998-03-20
Abstract: PROBLEM TO BE SOLVED: To reduce the incidence of stuck-together pellts or grape-like pellets by a method wherein a melted resin film formed on a die surface is solidified by being sprayed with cooling water. SOLUTION: An annular plate 13 is fixed to the shaft supporting part 12 of a holder shaft 11. At both the sides of the plate, atomizing nozzles 14 are attached. Cooling water pipings 18 including a pump 15 or the like are connected to both the atomizing nozzles 14. Cooling water is atomized in mist against a die surface and cutters 5 from both the atomizing nozzles 14 so as to cool and solidify and peel off a melted resin film formed on the die surface. The stomizing angle is adjusted by changing the rotational frequency of the pump 15 and the pressure of cooling water. Cut pellets fall in the cooling water 2, which spirally runs on the peripheral surface of a cutter hood 1, and are cooled down and, at the same time, carried to an outlet 7.  After that, the pellets are fed to an centrifugal drier and an automatic sifter so as to select single pellets, which are products, from stuck-together pellets and grape-like pellets. Thus, the incidence of stuck-together pellets or grape-like pellets an be reduced.

Title: Manufacture of semiconductor laser
Inventor: YAMADA HIDEYUKI
IPC: H01S5/00
Filed: 1989-03-23
Abstract: PURPOSE:To enable easy manufacture of a high output semiconductor laser by performing annealing through ion implantation of an N-type dopant to a surface of a laser resonator which is made by dividing a multilayer structure including an active layer which is concerned with light emission in a non-current injection region. CONSTITUTION:A non-current injection region 51 whereto a current is not injected at fixed intervals is provided to a multilayer structure including an active layer which is concerned with light emission. The multilayer structure is divided in the non-current injection region 51 and annealing is carried out through ion implantation of an N-type dopant to a resonator surface 60 (edge face) of a semiconductor laser. Accordingly, a practical band gap energy is increased and light absorption of a laser light which is produced through current injection excepting in an area near an edge face of the semiconductor can be greatly reduced. Thereby, an edge face breakdown which obstructs a high output operation can be restrained, thereby increasing a maximum output.

Abstract: PURPOSE:To control automatically power supply even in a packet switching network by receiving and analyzing data transmitted from a host computer and turning on the power source of a terminal if this data coincide with a preliminarily indicated sequence data. CONSTITUTION:Line specifications and a synchronizing pattern SYN are indicated to a line synchronizing logic circuit 22 by a switch 12, and a comparison sequence pattern of five characters ''POWON'' is stored in a pattern storage part 25 by a keyboard 13; and when a reception sequence pattern 14 is received from the host computer in this state, a comparing circuit 23 receives this pattern in the order of P, O,... through the logic circuit 22 and compares this pattern with contents of the storage part 25. When an end code ETX is received from the logic circuit 22, a signal line 29 is turned on to turn on the power source of a terminal 3 if data received from the host computer till then and data in the storage part 25 coincide with each other. Thus, a control interface line 5 is not used but a transmission/reception data line 15 is used to turn on the power source.

Title: Method of filling foam particles of synthetic resin into mold
Inventor: KASAHARA SHIGERU
IPC: B29C44/00
Filed: 1986-04-01
Abstract: PURPOSE:To be capable of a remarkable reduction of an energy cost for filling foam particles into a mold by producing a suction force of a feeder by the amount of the wind generated by a blower of wind pressure below a specific pressure and by carrying the foam particles to fill the mold under virtually normal pressure using its suction force. CONSTITUTION:A pressure indicating controller PIC is a controlling device to make a pressure in a mold approximate virtually to an atmospheric pressure and the one end is in the mold and detects the pressure of the exhausted gas. By means of PIC, one of them works for opening and closing of the wind control valve 5 and the other works for opening and closing of the discharge valve 7 into the air. The air sucked out of an intake vent by the operation of a blower P is injected into the cavity of the mold out of a feeder 2 through an air supply line 5. In this case, a pressure difference is generated in the feeder 2 and the particles in a raw material tank D are sucked into the feeder 2 through the transfer pipe 10. Following this, the sucked particles are injected and discharged by the gas passing through the feeder 2 and filled into the cavity of the mold C. The suction force generated in the feeder can be produced by the amount of the wind of the blower under less than 0.1kg/cm<2>G wind pressure.

IPC: G06F3/08
Filed: 1995-03-30
Abstract: PURPOSE: To provide an optical disk device capable of operating the speed of an optical head without using a division operation much in burden on a device. CONSTITUTION: A control signal arithmetic part 12 respectively inputs a detected count number Cd corresponding to the present speed of the optical head 4 from a count number detection part 8 and a reference count number Cr corresponding to the number of remaining tracks to be seeked from a reference count number instruction part 11. Then a pseudo speed difference is obtained by bit-shifting the value of (Cd-Cr) corresponding to the value of (Bd2-Br2) by setting Br to be a power of two nearest to Cr, Bd to be a power of two nearest to Cd, Bd2 to be the integer part of logarithm of the two bases of Cd and Br2 to be the integer part of the logarithm of two bases of Cr. This pseudo speed difference is utilized instead of a speed difference being difference between a value reference speed and a detected speed to unnecessitate the division operation.

Title: Casing structure of rotary valve
Inventor: OGUMA TETSUO
IPC: B65G65/48
Filed: 1985-04-05
Abstract: PURPOSE:To obtain a casing structure of a rotary valve which can restrict damage to the casing for improved durability by embedding hard material such as stellite in recessed grooves formed in steps on the inner surface of a casing. CONSTITUTION:When a rotor 7 is rotated and granule is supplied through a supply port 2, the rotor 7 and a housing 1 cooperate to permit quantative ejection of granule through an exhaust port 3. At this time, negative pressure due to rotation of the rotor 7 causes granule to reversely flow within the housing 1, and thereby granule is caught between blades 7b and the housing 1, resulting in, what is called, galling effect on the inner surface of the housing, which will be restricted by high hardness property of the hard material 9, and even if some pinholes are formed, the hard material 9 restricts expansion of the damage, thereby improving durability of the housing 1.

Abstract: PURPOSE: To automatically adjust the vertical rolls' gap, to carry out the desired vertical rolling work, and to contrive the improvement of the product quality, by connecting the position detector for both side edges of the horizontally rolled material and the vertical mill's roll position detector to the arithmetic unit.  
     CONSTITUTION: The position of the horizontally rolled material 2 is detected by the side edge position detectors 4, 4', whose signals are sent to the screw down motors 5, 5', through the arithmetic units 8, 8', and the vertical mill's rolls 3, 3', are displaced. Hereby, the center of the gap of the rolls 3, 3', is set to the lateral center of the rolled material 2. When the material 2 is horizontally rolled and vertically rolled, the loads of the rolls 3, 3', are detected by the load detectors 6, 6', whose signals are sent to the arithmetic units 8, 8'. When these detecting values are different from the set points, a signal is sent to the screw down motors 5, 5', for adjusting the gap of rolls 3, 3'. As a result, the desired load is impressed on the material 2, and the vertical rolling work is carried out so as to obtain the desired sheet breadth.
