Patent JP-S5889334-A (JP)
Title: Injection molding metal die
Inventor: KITAGAWA SEIICHIROU
IPC: B29C45/80
Filed: 1981-11-24
Abstract: PURPOSE:To improve homogeneity and surface precision by a method wherein after plastic resin material is injected and the die is filled with the resin, the resin is compressed by a movable die, an injection valve is closed by a return valve and the force of a plunger operated  by the return valve to prevent the resin from flowing backward and to supplement resin by the bulk reduced by cooling. CONSTITUTION:The movable retainer plate 8 is stuck by the direct pressure of an injection molding machine to the retainer plate 7 to close the forces and to supply resin material under pressure between the forces. The resin material reaches the passage 5 through the spool 23, pushes the valve spring 6, opens the valve head 4a and is injected into the cavity 16. If pressure is applied to the hydraulic passage 18 when the resin is semi-cured immediately after the injection and filling process end, the piston 19 slides, the molding force is pushed and the resin is compressed. When the forced supply of the resin is stopped at the same time, the force of the valve spring 6 is superior to the hydraulic pressure. Both spring pressure and compressed backward resin pressure pushes the valve head 4a firmly to the valve seat 3 to shut the gate 2. The value head 4a controls the plunger 10, which compensates excessively the small bulky reduction in the subrunner 25 due to the movement of the valve head 4a. After resin material has been cured, if the retainer plates 7, 8 are separated from each other a complete article can be taken out.

Filed: 1988-07-27
Abstract: PURPOSE:To perform a correct program searching operation by sending a start identification STID signal outputted from a digital interface for a prescribed time decided by specification even when a flaw, etc., is generated on a magnetic tape. CONSTITUTION:An (n) time coincidence detection circuit 661 decides the level of the output of the start identification STID by a count clock pulse, and outputs a pulse when a prescribed number of times 1 is detected. An FF 663 is set by the output, and outputs a signal set at 1 until being reset. Simultaneously, a counter circuit 662 is also reset, and the counting of the count clock is started, and a reset clock is outputted until a value arrives at a prescribed value, then, the FF 663 is reset. Therefore, the signal set at 1 is outputted for the prescribed time even when a defect exists in the STID signal. The signal is inputted to an I/O formating circuit 651, and the signal suitable for the specification is outputted to a DAT 2. In such a way, it is possible to perform the correct program searching operation.

Title: Error signal generator for optical reproducer
Inventor: YASUDA HIROSHI
IPC: G11B7/09
Filed: 1985-08-28
Abstract: PURPOSE:To reduce the gain variation despite the servo position control by using two sets of two resistances connected in series which are set between the output and the inverse input of an operational amplifier and a variable resistance having its middle point connected to said two sets of resistances and grounded. CONSTITUTION:The output (A1+A3) at a single side of a four split optical detector 1 undergoes the I/V conversion and is turned into the output (d) by an operational amplifier 2, the resistances 8-10 and the resistance ranging up to the middle point of a variable resistance 11. While the output (A2+A4) at the other side of the detector 1 undergoes the I/V conversion and is turned into the output (e) by an operational amplifier 3, the resistances 12-14 and the resistance ranging up to the middle point of the resistance 11. These outputs (d) and (e) of amplifiers 2 and 3 undergo subtraction through a subtractor 6 and then undergo the gain control through a gain control resistance 7. Thus an error signal (d-e) is delivered. Thus, the gain is not changed so much even though the servo position control is carried out after the gain control. This facilitates the easy control of gain.

Title: Mixing and dispersing apparatus in molten resin extruder
Inventor: FUKASE HISAHIKO
IPC: B29C48/395
Filed: 1980-12-27
Abstract: PURPOSE: To prevent over-deterioration of a material as well as to enable to disperse the same in an extremely high degree by a method wherein a ratio of a respective blade length of a movable blade and a stationary blade and a flow passage between blades is set in a specific range as well as the movable blade and the stationary blade are alternatively arranged in plural stages.  
     CONSTITUTION: When a barrel 10 of an extruder is heated and resin material 14 is thrown thereinto from a hopper 13, the material 14 is moved according to rotation of a screw 5 and converted to an almost molten liquid form until reached to a leading end 9 thereof. The material flowed into a stationary blade 3' loses a circumferential speed because a blade length is sufficiently long compared to a distance between blades and advanced to an axial direction. In this case, when a blade row of a first stage comprises movable blades 3, even if the material passes the movable blade row, dispersion is not generated. When the material entered into the movable blade from the stationary blade, a blade length 1 related to a width w of a flow passage between blades may be adjusted to a formula 1/w≥0.5.

IPC: B41N3/03
Filed: 1985-08-28
Abstract: PURPOSE:To provide a direct drawing type planographic plate material which does not need a desensitizing treatment, by providing an image-receiving layer comprising an inorganic pigment, carboxy-modified polyvinyl alcohol, a polyamide-epichlorohydrin resin and meso-inositol hexaphosphate or a derivative thereof as main constituents, on a base. CONSTITUTION:An aqueous coating material comprising an inorganic pigment, carboxy-modified polyvinyl alcohol, a polyamide-epichlorohydrin resin and meso- inositol hexaphosphate or a derivative thereof is applied to the base, and is dried at 100-160 deg.C to provide an image-receiving layer in an amount of about 2-30g/m<2>. Since the polyamide-epichlorohydrin resin is used as a water-resisting agent, formaldehyde is not generated, and an image-receiving layer more hydrophilic than that obtained by using a melamine-formaldehyde resin is provided. Since a coating material comprises meso-inositol hexaphosphate or a derivative thereof, this desensitizing agent strongly combines with carboxy- modified PVA at the time of forming an image-receiving layer, so that the resultant planographic plate material does not need a desensitizing treatment.

Filed: 1988-07-28
Abstract: PURPOSE:To obtain an artificial bone utilized in state implanted in a living body or bone cement by mixing tricalcium phosphate, an acid, protein, water and hydroxyapatite, and setting and curing the resulting mixture. CONSTITUTION:A raw material of an artificial bone mainly consists of an alpha-type tricalcium phosphate powder, an acid, water-soluble protein 2, water and granular hydroxyapatite 1. These components are mixed in a proper ratio to cure the raw material by the reaction based on the hydration setting of alpha-type calcium phosphate, the acid and water. In this case, protein becomes a skeletal to give sufficient strength to the set body and the strength withstanding the use as the artificial bone is obtained. Further, the addition of hydroxyapatite makes the cured material harder and difficult to absorb. The mixing ratio of the above mentioned components is controlled corresponding to a use purpose and a particle size is also selected. This mixture can be formed into an arbitrary shape during a curing process.
