Title: Screwing socket
Inventor: ISODA MASAAKI
IPC: H01R33/96
Filed: 1992-08-26
Abstract: PURPOSE:To completely prevent an electrical shock by providing structure where a current is not easily supplied even if a human hand is accidentally inserted when a bulb is not disposed. CONSTITUTION:A screwing socket is provided with a socket metal 14 for screwing a bulb 21 and positive and negative terminals 6, 11 exposed to a bulb inserting portion A. One of the positive and negative terminals 6, 11 is connected to a terminal portion 5 on a side of a power source via a plate spring 10 for opening or closing a contact, having a contact 12 which can be freely brought into or out of contact therewith. The socket metal 14 is disposed movably in the direction D opposite to the screwing direction C of the bulb 21. When the socket metal 14 is moved in the direction D opposite to the screwing direction C of the bulb 21 against resilient force of a return spring 20, the contact 12 is brought into contact with one of the terminals 6, 11, thus leading to a continuity state. If the bulb 21 is not disposed, it is possible to prevent easy continuity even when a human hand is accidentally inserted.

Title: Injection molding method
Inventor: MINAMIMURA MASAAKI
IPC: B29C45/77
Filed: 1993-08-20
Abstract: PURPOSE:To make injection molding also of a molded product which is thin and has a large projection area easy, by a method wherein injection and filling of resin are performed by low pressure and inner pressure of a mold is equalized before dwelling. CONSTITUTION:Mold clamping force to be set up at an ordinary injection molding is taken as rated pressure and a mold is clamped by the clamping force lower than the rated pressure. Resin is injected and filled into a cavity by injection pressure of such an extent as to generate a gap corresponding to the mold clamping pressure and allowing an outflow of only gas. At a point of time when the cavity is filled with the resin, injection pressure is removed by interrupting temporarily injection and filling and the pressure is allowed to equalize by lowering the pressure. Dwelling is performed by boosting the injection pressure by boosting the clamping force up to the rated pressure.

Filed: 1987-09-10
Abstract: PURPOSE:To flatten spectral responsivity characteristics, and to reduce the dispersion of photoelectric conversion efficiency by laminating and forming a first insulating film and a second insulating film onto the surface of a semiconductor layer and selectively removing the second insulating film through etching on the main region of the surface of a light-receiving section.

Title: Heat transfer pipe
Inventor: TAKAHASHI KENJI
IPC: F28F1/40
Filed: 1982-12-27
Abstract: PURPOSE:To improve greatly the heat transfer rate, by forming notches in a spiral ridge on a pipe body inner surface, the depth of the notches being shallower than the height of the ridge, so that the whirls behind the thus formed projections are diffused by the streams flowing along the groove between the turns of the spiral ridge. CONSTITUTION:A fluid flows out of the notches 4 in the ridge 2 and forms whirls in the groove 6 behind the projections 5 and also forms whirls in the groove 6 behind the ridge 2. On the other hand, as the groove 6 is in the form of a spiral, the fluid in the groove 6 is subjected to the force of the main stream 7 to form a stream along the groove 6. As a result, the whirls formed behind the ridge 2 and the projections 5 are forced to flow without remaining there. Due to the interaction between the whirls, complicated secondary streams having a speed constituent normal to the main stream 7 are generated. Thus complicated whirls are formed and as these complicated whirls are diffused, the mixing of the fluid can be carried out efficiently, and the heat transfer rate between the fluid and the heat transfer surface can be greatly improved.

Filed: 1983-12-01
Abstract: PURPOSE:To detect a correct stop position by detecting the position based on a point of time when two stop line (position) detecting outputs are coincident in detecting the stop position of an unattened track. CONSTITUTION:Coils 1, 2 apply respectively an output corresponding to a magnetic field from a stop line 4 to detection rectifier circuits 10, 11. The detection rectifier circuits 10, 11 detect and rectify the output of the coils 1, 2 and apply it to each input of a differential type comparator 12 and input of a summing point 13. The comparator 14 compares the added output of the summing point 13 with a preset level Vref, and when the summing output exceeds the level Vref, an enable signal is outputted to a comparator 12, which is activated. When the unattended track goes forward and reaches the stop position, an output of the comparator 12 goes from an L level to an H level, and when the unattended track goes back and comes to the stop position, the output of the comparator 12 goes from an H level to an L level. A differentiation circuit 15 outputs a pulse signal to an output terminal 17 at the leading of the input signal and a differentiation circuit 16 outputs (18) to a pulse signal at the trailing of the input signal.
