Namely, the grating 3 consisting of a dielectric material is formed on a transparent substrate 1 and the sectional shape thereof is formed to a saw tooth shape. The +1st-order diffracted light diffracted to the right side is stronger than the -1st-order diffracted light diffracted to the left side with the saw tooth-shaped grating 3 and, therefore, the higher light utilization rate than in the case of the grating symmetrical with the center is obtd. The bidirectional grating optical element having the high utilization rate of light is thereby obtd.

Filed: 1987-11-13
Abstract: PURPOSE:To make it possible to stably operate a refrigerating cycle by providing means for maintaining for a predetermined time the rotational speed of an outdoor fan after a predetermined time from the start of the operation, irrespective of the detected temperature of a heat exchanger temperature sensor. CONSTITUTION:At the time of a space cooling operation, in accordance with the comparison result of a detection temperature (temperature of a condenser) Tc of a heat exchanger temperature sensor 7 and a set value, the rotational speed N of an outdoor fan 6 is changed over to a high speed rotational speed NH or a low speed rotational speed NL to perform a stable control of a high pressure. However, until a predetermined time TO has passed from the start of the operation, a set value is set to a value TH' or TL' which is lower than the ordinary time value whereby the outdoor fan 6 is changed over from a low speed rotation to a high speed rotation, and an abrupt increase of the high pressure can be suppressed. After a predetermined time TO from the start of the operation, the set value is made into the ordinary value TH or TL. Upon the changeover of the rotational speed after the predetermined time TO, the rotational speed as it is, is maintained for a predetermined time T1, irrespective of the variation of the condenser temperature Tc. Thereby, the stable operation of the refrigerating cycle can be secured, the comfortableness and the life of the machine and apparatus can be improved.

Title: Remote controller and reception control method for the same
Inventor: TERANISHI TETSUO
IPC: E05B83/36
Filed: 1996-10-30
Abstract: PROBLEM TO BE SOLVED: To prevent battery exhaustion and to always keep a reception enable state by changing the reception cycle of a prescribed signal so as to reduce current consumption rather than ordinary time when a prescribed operation is not executed for a prescribed period. SOLUTION: When a received ID code is coincident with the ID code allowed to a device, a CPU 207 of a reception circuit 202 sends an 'engine start/stop signal' from an output circuit 206 through a centralized controller 205 to an ECU 203. That operation and the time of execution are stored in a non-volatile memory 204 as an operation history in the past. When the start/stop operation of an engine is not execution for a long time, for example, based on the operation history in the past stored in the non-volatile memory 204, the CPU 207 changes the reception cycle of 'engine start/stop signal' and 'ID code' from a transmitter so as to reduce current consumption rather than ordinary time.
