Then, the lengthwise direction of pixel electrode wiring 14 and common electrode wiring 13 is irradiated with ultraviolet rays having a polarizing axis at 80 deg., for example, and a liquid crystal orienting processing is performed. Since a liquid crystal molecule is oriented while being deviated from the polarizing axis of the ultraviolet light at 90 deg. by this orienting processing, the long axis of the liquid crystal molecule is oriented while forming the angle of 10 deg. with the lengthwise direction of pixel electrode wiring 14 and common electrode wiring 13.

Under this condition, when the temperature of cooling water is lower than a predetermined value, an electromagnetic coil 42s is not energized since a temperature switch 48 is opened, and therefore, a valve 34 in a diaphragm device 37 is opened. Accordingly, exhaust gas flows into an intake air heating chamber 31 for heating the mixture. Meanwhile, when the above-mentioned movable contact M is made into contact with a gaseous fuel side L, electromagnetic coils 25s, 42s are energized. Thereby, fuel in a tank 29 is fed through a regulator 23 and jetted from a nozzle 21, and as well the intake air heating by exhaust gas is interrupted.

Filed: 1981-03-19
Abstract: PURPOSE:To smooth the ascending and descending motion of a ram and to minimize the unstable motion of the ram owing to eccentric load, etc. by disposing a slidable crank pin metal inclinatorily to the ram. CONSTITUTION:A crank pin metal 1 is constittued to such a slide block or slide metal that can be slided, and this is fitted and located to an inclined sliding part 3 formed or disposed to a ram 2. More specifically, this is a ram device disposed inclinatorily at a prescribed angle to the rotating direction.

Title: Electronic range
Inventor: KOJIMA TOSHITADA
IPC: H05B6/68
Filed: 1987-02-20
Abstract: PURPOSE:To prevent even a packaged food from being overheated to carry out optimum cooking by continuing heating 1-2 times the time passing from the start of heating to a detection time point when the standstill of the temperature rise or the temperature fall is detected by an infrared ray sensor. CONSTITUTION:After starting the heating, a predetermined period DELTAT is set, and thereby whether the rise in the temperature detected by an infrared ray sensor is in standstill or the temperature falls or not, is judged. If the rise in the temperature is not in standstill or the tempperature does not fall, the judging procedure is repeated. If the temperature is kept on rising until the temperature reaches a cooking temperature thetam, heating is then stopped after the elapse of a time K1T1. If the rise in the temperature is in standstill or the temperature falls even once until the temperature reaches the cooking temperature thetam, the heating is continued over a period of time K2T2 which is K2 times the time T2 passing from the start of heating to a time at which the standstill or fall has been detected. By this procedure, even if the food has a tendency shown by either of curves A and B, the heating control can be carried out automatically in accordance with the food.
