Title: Method and apparatus for injection molding
Inventor: NISHIDA SHOZO
IPC: B29C45/36
Filed: 1990-06-26
Abstract: PURPOSE:To obtain a large injection flow rate by a low injection pressure and to prepare a molded item with precise shape and dimension by injecting a molten resin in a cavity through a number of fine holes of a multihole member forming a part of a wall dividing the cavity. CONSTITUTION:A molten resin kept at a specified temp. passes through a path 10b from a nozzle hole 18a of an injection apparatus 18 and flows into fine holes of a multihole member 12 through a manihold chamber 10a and flows in a cavity A. The molten resin is filled in the cavity A and a molded item P is molded. A movable mold 8 moves a little to the left to form a gap B between the movable mold 8 and a fixed mold 4. By this movement, the molten resin in the fine holes of the multihole member 12 are drawn into a fibrous shape and a number of these resin fibers are stretched over between the molded item P and the fine holes. Air at a low temp. is fed in a blast nozzle 20a from a cooling air feeding apparatus 20 and the air cools and solidifies a number of resin fibers and is then evacuated out of the molds 4 and 8. Mold opening is performed and the molded item with a number of fibrous resin are separated and the molded item is taken out.

Title: Sense amplifier circuit
Inventor: YAMAGUCHI TAKANORI
IPC: G11C16/06
Filed: 1996-06-27
Abstract: PROBLEM TO BE SOLVED: To lower precharging level of a bit line to improve noise margin by installing, in an sense amplifier circuit, a circuit which controls threshold voltage of an NMOS for switching by a precharging signal. SOLUTION: While a precharging inversion signal is 'Low' level, a PMOS P1 is on, and an electric potential of a node a is precharged up to source voltage. Output OUT of a threshold control circuit 8 becomes 'High' level by the precharging inversion signal to turn on an NMOS Nl, and an electric potential of a node b is raised. When the electric potential of the node b is raised, and logical threshold voltage of the threshold control circuit 8 becomes H level or more by the precharging inversion signal, the output OUT becomes Low. Thereby, the NMOS N1 for switching is off, and precharging of the node b is terminated. The electric potential difference between 'High' and 'Low' of the threshold control circuit 8 can be noise margin, therefore stable operation with improved noise margin is achieved.

Filed: 1985-07-31
Abstract: PURPOSE:To enable an operator to decide comparatively simply the cause of an error generated in a character reader by displaying a character pattern for one sheet stored in a sheet buffer memory means. CONSTITUTION:If an error is generated in read processing generating many rejects in accordance with the recognized result of a character recognizing part 25, a control part 11 displays the contents of a sheet buffer 29 on the screen of a CRT display device 12.

Abstract: PURPOSE:To store a program into a memory area of the RAM of a memory circuit and to simplify a debugging job by selecting the memory area of the RAM instead of a memory area of the ROM of the memory circuit in a test mode. CONSTITUTION:A state holding circuit 14 outputs a state signal ROMS in a set state. Then a memory circuit control part 12 which inputted the signal ROMS and an address decoding signal received from an address decoding part 11 outputs the selection signals of a normal mode for selection of a ROM 21 of a memory circuit 20 and the memory areas of RAM 22-24. At the same time, the circuit 14 turns on a resetting switch 32 for input of a resetting signal and outputs a state signal RAMS in a reset state. While the part 12 outputs the selection signals for selection of the ROM 21 and the memory areas of the RAM 22-24 in a mode different from a normal mode. Thus a program to be debugged is stored in the RAM 24 instead of the ROM 21 and therefore a debugging job is simplified.

Title: Fiber type heat sensor
Inventor: SUETSUGU YOSHIYUKI
IPC: G01K5/48
Filed: 1988-07-08
Abstract: PURPOSE:To identify a heat detected position with a simple arrangement by using the local microbending loss of a covered optical fiber caused by the contraction of thermo-contracting material. CONSTITUTION:A thermo-contracting material 3 is arranged in a thermo- contracting material housing part 11A under a state in which only one edge 13a of the material 13 is fixed, and a covered optical fiber 12 is fixed linearly along the thermo-contracting material 13 onto fixing points A and B at both edges of the material 13 in the thermo-contracting material housing part 11A. Consequently, when the ambient temperature becomes high, and the thermo- contracting material 13 contracts by heat, the covered optical fiber 12 meanders between the points A and B, and optical transmission loss caused by microbending increases. Thus, time of day and the place where the ambient temperature of the title fiber type heat sensor rises can be accurately detected by continuously monitoring the longitudinal directional optical transmission loss distribution of the covered optical fiber 12 by a back scattering light measuring instrument.
