Title: Defect detection system for recording medium
Inventor: YOSHIZOE TERUHIDE
IPC: G11B5/02
Filed: 1983-09-30
Abstract: PURPOSE:To detect the deterioration, defect, etc., of a recording medium before the output of the recording medium drops until data processing is disabled by grasping the state of the recording medium by utilizing the output of a servo waveform. CONSTITUTION:Each recording track of the recording medium is read by a write head 20. The servo waveform (a) is amplified by a write amplifier 21, and when timing signal (b)-(e) from a rotor tachometer decoding circuit 23 arrives, an analog peak holder 22 holds the output voltage level of the current servo waveform to send respective held voltages (f)-(i) to an analog switch 24. Consequently, an error due to noise is removed effectively. The analog switch 24 is applied with a reference voltage V0 from a reference voltage generating circuit 25. If the servo waveform deteriorates or has a defect, the held voltage corresponding to the waveform drops below the reference voltage V0. Then, the analog switch 24 is turned on only when the respective held voltages (f)-(i) are within the range of the reference voltage V0 to send the output to a counter 26.

Title: Mold for injection molding and manufacture of molding with design
Inventor: TANIGUCHI TADATAKE
IPC: B29C45/72
Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To upgrade a balance of deformability between both surfaces of a non-close contact side and a close contact side of a film in an injection mold by forming a film heating hole at a parting surface or a cavity forming surface with which the film introduced into the mold for injection molding is brought into close contact. SOLUTION: A film grasping means for grasping a film 1 is approached to a cavity forming surface of a mold. An endmost side of the film 1 projected from the means is fixedly delivered to a temporarily fastening member 12 of the parting surface. Both a non-close contact surface and a close contact surface of the film 1 are heated by heating means. In this case, a distance between the heating means of the non-close contact side surface and the film is separated more than that between the heating means of the close contact side surface and the film. A fixed mold and a movable mold 5 are closed to sandwich the film 1 therebetween, molten resin is injected from an injection gate. Thus, while an adhesive layer of the film 1 remains in contact with the molten resin, the molten resin is cooled, solidified, and the film 1 is adhered to a molding.

Title: Clock switching system
Inventor: HARANO HIROSHI
IPC: H04L12/42
Filed: 1991-06-28
Abstract: PURPOSE:To automatically switch the clock of a slave device to the clock of an opposite transmission line without hands at the time of the occurrence of transmission trouble in a synchronous ring network. CONSTITUTION:Normally, a clock is extracted from transmission data of a master device and slave devices are operated synchronously with this clock in the ring network connected by two transmission lines for transmission in opposite directions between devices. If the occurrence of trouble is detected, the slave device which detects trouble switches this clock to the clock of the device itself. A numerical value as trouble information is successively incremented to transmit an overhead signal to the master device. Since this numerical value is so returned from the master device that the clock is extracted from transmission data in the opposite direction, slave devices switch the clock to the clock extracted from transmission data in the opposite direction in the order from the slave device nearest the master device based on this returned information.

Abstract: PURPOSE: To prevent malfunction of a water cock by absorbing excessive pressure created by thermal expansion of water in the enclosed region between a water chamber and a check valve when only hot water is being discharged.  
     CONSTITUTION: A valve shaft 23 is inserted free slidably in the direction of a water pipe to a valve holder 22 at a connecting passage 19 between a water chamber and a check valve 20; a cup shaped rubber valve member 24 easily deformable by external pressure is attached to the tip of said valve shaft 23.
