IPC: B29C51/00
Filed: 1981-04-24
Abstract: PURPOSE: To manufacture a hollow body with a voidless decorative skin effectively by a method wherein a skin sheet is disposed on a hollow core material provided with an air-escaping concave groove on the surface and coated by suction or press-fitting.  
     CONSTITUTION: After a molding core material 2 is mounted on a vacuum molding base 6 the surface of the core material 2 is coated with thermoplastic synthetic resin adhesives 7. The skin sheet 8 of thermoplastic synthetic resin such as foamed vinyl chloride sheet having softening given by heating is disposed on the core material and the air in the sealed cavity is absorbed and extracted through each air vent 9 of the molding base 6. When the inner part of the cavity becomes vacuous the skin sheet 8 is adsorbed by the surface of the core material 2 and stuck to it. At this time, the air between the skin sheet 8 and the core material 2 is absorbed and extracted amply from the concave groove 5 established on the surface of the core material 2 and a voidless product is obtained wherein the skin sheet 8 of the skin material 2 is coated nicely with adhesives.

Filed: 1989-03-13
Abstract: PURPOSE:To eliminate an influence caused by a delayed response of a thermo-couple at an initial stage of ignition, provide a stable ignited state, prevent a noise of resonance sound and further prevent a red heat of a burner plate by a method wherein an air fuel ratio correcting means is provided with a time counting means for counting an elapsed time after ignition and a reference temperature is set low until a predetermined time elapses after ignition. CONSTITUTION:In case that a temperature of a thermo-couple 15 is low and its output voltage is lower than a reference voltage Vs, an initial reference voltage Vs0 corresponding to an elapsed time (t) is calculated at an air fuel ratio correction part and a calculation of this initial reference voltage Vs0 is repeatedly carried out unless the elapsed time (t) exceeds a predetermined time (ta). In case that an output voltage V of the thermo-couple 15 is lower than the initial reference voltage Vs0, fuel gas of which fuel supplying volume is increased under a correction of fuel is injected out of a nozzle 13. Accordingly, much volume of fuel gas in respect to the combustion air is supplied in a mixing chamber 10b, resulting in that a gas rich state is attained and a positive ignition is attained. Thereafter, as the elapse time (t) after ignition to be counted with a timer part continues, the initial reference voltage Vs0 is gradually increased.

IPC: G06F17/30
Filed: 1999-03-09
Abstract: PROBLEM TO BE SOLVED: To automatically eliminate unneeded information even though a user side does not take stored information contents into consideration. SOLUTION: In this information elimination processing method, a CPU 11 compares the keyword of inputted valid information with the keyword of valid information stored in a storage device 12 in storing the valid information inputted by an inputting part 14 in the device 12 and adds the number of relations corresponding to the number of keywords to the valid information to discriminate whether or not to be important when plural numbers of coinciding keywords exist on the basis of the compared results.  And the CPU 11 can discriminate whether or not the valid information stored in the device 12 is important information by discriminating whether or not the number of relations is equal to or more than a prescribed number in a time interval set to a timer 13 and eliminates any valid information whose number of relations does not reach the prescribed value, i.e., eliminates insignificant valid information on the basis of these judged results.

Title: Method for growing gaas single crystal
Inventor: TSUJI TSUTOMU
IPC: C30B11/00
Filed: 1987-03-16
Abstract: PURPOSE:To enable the growth of a GaAs single crystal free from contamination with especially Si, by applying an oxide film having especially base free energy for Ga2O3 formation to an inner surface of a quartz boat and using the boat in the direct synthesis of Ga and As. CONSTITUTION:A GaAs seed crystal 6 and Ga 2 are put into a quartz boat 3 having a Cr2O3 film 1 of 0.5mum thick deposited by electron gun deposition process. The quartz boat 3 is placed at a side of a quartz reaction tube 4, As 5 is placed at the other side and the reaction tube 4 is sealed. The sides of Ga 2 and As 5 are heated at 1,250 deg.C and 610 deg.C, respectively. Vapor of As 9 is dissolved in the Ga 2 to form GaAS 8. The GaAs 8 is seeded under cooling to 1,238 deg.C from the As side 5 to effect the growth of a GaAs single crystal 7. Since Ga is perfectly separated from the reaction tube 4 during the above process, there is no contamination of Si from the reaction tube 4. The growth of crystal can be observed through the boat 3 because of thin thickness of the Cr2O3 film 1.

Title: Dynamic balance device for press machine
Inventor: ISHIBASHI SHIGEO
IPC: B30B15/06
Filed: 1989-03-13
Abstract: PURPOSE:To eliminate a bending moment for bending a crank shaft in the axial direction by placing a first and a second connecting rods in the same eccentric part of the crank shaft, and also, to shorten the dimension in the axial direction of a press machine by shortening the length of the crank shaft. CONSTITUTION:When a crank shaft 3 rotates, a slide 8 executes an up-and-down motion through a first connecting rod 6, and does not execute an up-and-down reverse motion but execute an up-and-down motion in the same direction since a first and a second connecting rods 6, 7 are placed in the same eccentric part 3A of the crank shaft 3. However, since a balance weight 18 is connected to the second connecting rod 7 through a moving direction inverting mechanism 19, the slide 8 and the balance weight 18 come to be opposed in the opposite direction to each other by this motion inverting mechanism 19, and a dynamic balance in the course of press working is secured. Since the first and the second connecting rods 6, 7 are not placed in the crank shaft 3 by separating them in the axial direction, a bending moment for bending the crank shaft 3 in the axial direction is not generated, and also, length of the crank shaft 3 can be shortened.
