Title: Contact heat molding
Inventor: TAKAI TOSHIHIRO
IPC: B29C51/06
Filed: 1995-08-07
Abstract: PROBLEM TO BE SOLVED: To prevent molding defects such as rain drops which tend to result from a condition of high heating temperature from being generated by heating a compressed air to be blown from a hot plate side under a contact heat molding method to a specific temperature. SOLUTION: Solenoid valves 36, 42 are opened in such a state that solenoid valves 32, 38 are closed. Consequently, a resin sheet S is vacuum-sucked through a tiny hole 11, and at the same time, is tightly stuck to a hot plate by the blowout of a compressed air into a cavity in a molding die 20. Next, the molding die 20 is lowered to press the peripheral edge of the sheet S. Then, if a command for starting a molding process is issued, the valves 36, 42 are closed, and the valves 32, 38 are opened. The compressed air heated to 80-120 deg.C by a heater 31 is sent to a relay chamber 12 passing through a feed pipe, and is blown out of the tiny hole 11 of the hot plate 10. Concurrently, the thermally softened sheet S is tightly stuck to the face of the cavity 21 of the die 20, being elongated, and then is molded by the vacuum-suction of the air from the cavity by a vacuum pump 40.

Title: Information reproducing device
Inventor: TANAKA SHINICHI
IPC: G11B21/10
Filed: 1983-11-29
Abstract: PURPOSE:To make it difficult that tracking control is disturbed by a defect of an information recording carrier, by switching the time constant of a high-pass filter to a small value when a defect is detected in a reproduced part of the information recording carrier and cancelling quickly a speed error just after detection when noise is mixed into a control signal just before detection because of delay of defect detection to generate the speed error in an actuator. CONSTITUTION:If a defect detection signal is outputted when a defective part of an information recording carrier 1 is tracked, a changeover switch 8 switches the signal to be inputted to a high-pass filter 12 from the error signal outputted from an error detecting circuit 5 to the output signal from a low-pass filter 11 and switches the time constant of the high-pass filter 12 to a small value. Thus, even if an impulsive noise remains because of delay of defect detection, the speed error due to this noise is canceled just after detection to stabilize tracking.

IPC: H04N1/00
Filed: 1994-09-20
Abstract: PURPOSE: To allow the controller to cope with various requirements of the users by allowing the user to release an image signal of an internal signal level not through a driver and a control signal of an internal signal level not through a driver/receiver in the inside of the controller. CONSTITUTION: An image reader is provided with an extension slot connector 42 and adopts the configuration that an extension slot 38 being a printed circuit board developed by the user is mounted in the inside. Then an image signal is outputted to the slot 38 not through a driver 74 and a control signal is given/ received with the slot 38 not through a driver/receiver 75.
