Patent JP-H08229988-A (JP)
Title: Die device with gate cut mechanism
Inventor: KANDA KATSUTOSHI
IPC: B29C45/38
Filed: 1995-02-23
Abstract: PURPOSE: To enhance the accuracy of a molding despite the difficulty to determine the position of a sprue bush accurately, and prevent a gate cut sleeve from malfunctioning. CONSTITUTION: The fixed half 1 of a die consists of a cavity member 7 for molding a finished product, in which an air blow sleeve 21 is embedded, and a sprue bush 24 which is engaged with the interior of the air blow sleeve 21. In addition, a gate cut sleeve 51 on a movable half 2 side is engaged with the interior of the air blow sleeve 21. Consequently, the sprue bush 24 does not form a finished product part. Further, the air blow sleeve 21 and the sprue bush 24 are aligned in that order, using the cavity member 7 as a reference. The sprue bush 24 can hardly be positioned accurately. However, any adverse effects caused by the positional accuracy of the sprue bush 24 can be prevented from occurring by the described sequential alignment. If the wear by the gate cut sleeve 51 becomes worse, the air blow sleeve 21 has only to be replaced, and thus cost is reduced.

Title: Heating apparatus for bathroom and draining floor
Inventor: ODA SO
IPC: E03C1/20
Filed: 1985-02-25
Abstract: PURPOSE:To perform heating for a bathroom and a draining floor by a simple structure, and to make it unnecessary to provide a special temperature controlling device for a heating mat, by connecting a hot-water forced circulation pipeline for a bathtub and a heating pipeline for a heating mat in series. CONSTITUTION:Hot-water heated by an outdoor heater 3 is forcibly sent by a circulation pump 1, and is injected into a bathtub from an injection and suction device 10 provided on the bottom of a bathtub 2. At the same time, the water in low temperature in the bottom part of a bathtub is sucked and is fed into a heating mat 7 to heat it through a connecting pipe 11. The water is returned again to the outdoor heater 3 afterwards. When the heating may is not used, a bypass valve 13 is shut off. A check valve 16 is changed over when the heating mat is to be heated in the first priority.

Title: Optical information recording and reproducing device
Inventor: SUMI TAKESHI
IPC: G11B11/105
Filed: 1990-02-16
Abstract: PURPOSE:To perform an always stable signal detection with high reliability by providing polarization separating elements on opposite surfaces held between the surfaces of two gratings respectively and arranging photodetectors on individual optical paths of transmitted light and diffracted light. CONSTITUTION:Reflected light (a) from an optical information recording medium 7 is incident upon the 1st grating 28 of an optical path separating element 4, so that the transmitted light T and the diffracted light K are separated from each other, and these two kinds of light T and K are reflected by a surface formed as a total reflection film 3a respectively and then passed through the 2nd grating 29 to be emitted outside, and are detected by the photodetectors arranged on the optical paths respectively. Consequently, the lengths of the optical paths for the transmitted light T and the diffracted light K from their separation by the 1st grating to their detections by the photodetectors 31 and 32 are both equalized, and their spot diameters on the photodetectors 31 and 32 on the same surface are also equalized with each other. By this method, the always stable signal detection with high reliability can be performed without necessity of making the fitting accuracy for the photodetectors severe.

Title: Controller for ac/dc converter
Inventor: ISHIYAMA HIDEKO
IPC: H02M7/515
Filed: 1995-02-23
Abstract: PURPOSE: To suppress the disturbance on a sound system while sustaining the interchange of effective power by advancing the phase lead control angle of an inverter without interrupting an AC/DC converter when the AC system voltage drops below a predetermined level on the converter side. CONSTITUTION: If an AC/DC converter 4B drops down to a predetermined level possibly causing continuous commutation failure when an AC/DC converter 4 is operating as a converter and the operation is continued with the voltage of an AC bus 2A detected through a protective circuit 32A being lowered asymmetrically, the protective circuit 32A delivers a phase advance control command to a phase advance control circuit 27B on the AC/DC converter 4B side operating as an inverter in order to suppress continuous commutation failure. It is also true when the AC/DC converter 4 is operating as a converter and the voltage of an AC bus 2B detected through a protective circuit 32B is lowered asymmetrically. With such arrangement, DC power can be interchanged continuously even upon failure of the AC system and disturbance on the sound AC system can be suppressed.

Title: Electrode for excimer laser
Inventor: KUWAE YOSHINORI
IPC: H01S3/038
Filed: 1987-02-20

Abstract: PURPOSE: To make an opening with a sharp edge when exposing a photosensitive material coated on the surface of a substrate, to light to make a prescribed pattern, by using diferent patterns and effecting overlap exposure.  
     CONSTITUTION: A pair of pattern chips 12a, 12b, each of which is Amm long in  one side and Bmm long in the other, are placed in contact with each other on a  reticle 1 to make an opening. The tips 12a, 12b are provided with main patterns  13a, 13b, which are made different from each other so that the prescribed square  opening is not made until the main patterns are moved pitch by pitch and overlapped with each other. The paterns 13a, 13b are sequentially moved by a pitch of  Bmm stepwise repeatedly to perform exposure to manufacture a master mask 14.  Since the two different patterns 13a, 13b are overlapped with each other to make  the single opening, the edge around the opening is not round but sharp.
