Title: Line pressure controller for automatic transmission
Inventor: KASHIWABARA MASUO
IPC: F16H61/04
Filed: 1990-02-28
Abstract: PURPOSE:To avoid the drastic change of a line pressure at the time of the completion of the speed change by fixing input torque for setting line pressure during the transition of the speed change, and releasing the fixation after passing a given period from the completion of the speed change. CONSTITUTION:Line pressure setting means set a line pressure in response to the gear train input torque of an automatic transmission, however, input torque right before the transition of the speed change is not renewed by torque fixing means for setting the line pressure, but is fixed as it is, to eliminate any effect on the line pressure though the gear train input torque is changed due to the change of a speed change ratio during the transition of the speed change. Fixation releasing means do not release fixation just after the completion of the speed change, however, the means release the fixation of the torque for setting the line pressure first after passing a given period from the completion of the speed change. Thus, the drastic change of the line pressure at the time of the completion of the speed change can be avoided and the occurrence of problems such as the reverse of the speed change due to the quick reduction of the line pressure can be prevented.

Inventor: TOKUYASU TOMOHIRO
IPC: H04W72/04
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To obtain a base station equipment that can dynamically assign radio channels with a high efficiency without awaiting assignment by a central management station by allowing each radio base station unit to autonomously and distributingly a radio resource in response to a state of traffic. SOLUTION: A radio base station equipment 1 transmits a B burst to each radio terminal 2 at a prescribed interval, divides a period between the B bursts into times for time slots, provide phase numbers to them and assigns them to each terminal 2. The radio base station equipment 1 generates a packet group consisting of divisions of time slots with a fixed length when receiving data from a backbone network 3 and stores it to a transmission queue employing a FIFO function. When there is no interference from an adjacent base station in a preceding frame, a set time slot is assigned to a packet group that is not reserved, and a head packet is transmitted to try acquisition of the right of use. When the set time slot has already been reserved or there is any interference, the acquisition of the use of right for a succeeding time slot is tried in the setting order.  After the end of the entire assignment, a time slot is set to a packet group addressed to other terminal.

Filed: 1991-03-14
Abstract: PURPOSE:To improve the visibility by outputting a display switching signal, which is made long in switching time corresponding to a rise in the driving voltage signal of a power circuit, by a microcomputer for control. CONSTITUTION:The source voltages of temperature compensating circuits 5 and 6 of a liquid crystal display unit 9 are inputted to the microcomputer 7 which performs display control and ambient temperature is detected by using an A/D converter incorporated in the microcomputer 7. Then the display switching time is varied corresponding to variation in the response of the liquid crystal with the temperature. Namely, a liquid crystal driving power source 6 outputs a high voltage at low temperature and a low voltage at high temperature and those liquid crystal driving voltages are inputted to the control microcomputer 7. Then the display switching time is made long when the high voltage is generated and short when the low voltage is generated corresponding to the response characteristic of the liquid crystal. Therefore, even if the response of the liquid crystal deteriorates owing to a drop in the outside air temperature, the display switching time is automatically adjusted to long-time timing where the visibility of each display can be secured and to short-time timing at normal outside air temperature.

IPC: G03F7/20
Filed: 1996-02-13
Abstract: PROBLEM TO BE SOLVED: To prevent the dust appearing in a drive facility from entering an optical facility by letting clean air for temperature control flow in and pass through the optical facility first and then letting the air from the optical facility flow in and pass through the driving facility. SOLUTION: Air for temperature control of a specified temperature for temperature control which is sent out from an air conditioner 12 enters an air path 14 through an entrance duct 18 and a filter and passes through an optical facility and then a driving facility and is exhausted outside by an exhaust facility 16 through the air path 14 and an exit duct 20. Owing to this structure, the temperature of the optical facility is controlled by clean air for temperature control and therefore a defective exposure caused by the deposition of dusts to a wafer and a mask does not appear. Since the air in an aligner is forcibly exhausted by the exhaust facility 16, heat emitted by a light source never stay in the aligner. By this method, the temperature stability can be increased.
