Title: Actuator of constant-speed travelling device
Inventor: TOMINAGA TSUTOMU
IPC: B60W30/00
Filed: 1982-04-19
Abstract: PURPOSE:To precisely operate an actuator irrespective of any change in a suction air pressure, by arranging such that a negative pressure introducing tube of an actuator driven by a negative pressure in a suction air is provided with a negative pressure nozzle adapted to open at a constant amoung and close, while said nozzle is adapted to vary its opening amount in response to the negative pressure. CONSTITUTION:A throttle valve 13 in a suction air tube 12 is connected with a diaphragm 4 via a cable 15. Depending on a vehicle speed difference as computed through a control circuit 18, solenoid valves 7 and 8 for a negative pressure and an atmospheric pressure are caused to open and close, and thereby operating a disphragm 4 inside a pressure chamber 1. Provided intermediately at a suction air negative pressure introducing tube 19 of the actuator is a plurality of nozzles at least one 9a of which is adapted to open at a constant amount, while other nozzle 9b is adapted to control its opening amount depending on a suction air negative pressure. Thus, it is made possible for a valve 22 to open even when a suction air negative pressure is reduced while operating with an increased load, and thereby maintaining a constant flow rate of fluid to be introduced into the pressure chamber 1 and retaining a constant displacement of the diaphragm.

Title: Inverter control system in solar battery driving
IPC: H02P27/06
Filed: 1991-03-29
Abstract: PURPOSE:To control a solar battery at a point in the neighborhood of the maxi mum efficiency point with a simple constitution by setting a threshold voltage between the maximum efficiency voltage of the solar battery and a voltage at which a system goes down, and controlling the output frequency of an invert er based on whether the output voltage of the solar battery exceeds or goes less than the threshold voltage. CONSTITUTION:When a frequency command is outputted from a CPU 2 to the inverter 3 and the rotating speed of a pump 5 is increased by the inverter 3 via an induction motor 4, an input voltage from the solar battery to the inverter 3 is increased, and it arrives at a point in the neighborhood of the maximum efficiency point. When the rotating speed is tried to be increased further at the maximum efficiency point, the system goes down to prevent a power over that point from being taken out. In such a case, the threshold voltage Vsh shown as Voff<Vsh<Vmax assuming the maximum efficiency voltage of the solar battery as Vmax, the voltage at which the system goes down as Voff is set, and the output frequency of the inverter 3 is controlled based on whether the output voltage Vop of the solar battery exceeds or goes less than the threshold voltage Vsh.

IPC: H04B1/40
Filed: 1984-04-03
Abstract: PURPOSE:To confirm easily both a calling time and the calling itself by storing the group number data and time point data of control signals to a memory in a calling action mode and displaying each data as the call data when a user operates a display changeover switch to informing previously the group number to a calling subscriber. CONSTITUTION:The signals supplied through an antenna 1 of a personal radio set are demodulated to sound and control signals by a reception part 2. Then an NRZ signal is converted into a Hargelbarger code by a Hargelbarger decoder 4. The group number data in the control signal is compared with the 1st and 2nd waiting data fed from the 1st and 2nd waiting group number memories 6 and 7 by a group number coincidence detector 5.

Then the group number data and its time data are stored to a coincident group number data memory 11 and a time point memory 10 respectively. A user operates a display changeover switch 12 to display both the time data and the group number data of memories 10 and 11 to a display device 13. In such a way, easy confirmation of both a calling time and the calling itself is facilitated.

IPC: B42D15/10
Filed: 1991-03-30
Abstract: PURPOSE:To make information recorded on a thermal recording layer invisible, prevent forgery and interpolation by an iniquitous reading, and improve the thermal recording layer in light resistance. CONSTITUTION:On a substrate 2, a thermal recording layer 3, an ultraviolet light absorbing layer 4, and a hiding layer 5 transmitting an infrared light for making said thermal recording layer 3 invisible are successively laminated. When information is recorded on the thermal recording layer 3 by color forming in the form of a pattern, such as a bar code, characters, and numerals, a colored part (pattern forming part) absorbs an infrared light, and an uncolored part (pattern unforming part) reflects an infrared light at a high ratio. The pattern can be read by the difference in contrast. A visible light to the thermal recording layer 3 is interrupted by the hiding layer 5, whereby the information on the thermal recording layer 3 is prevented from being visually read. An ultraviolet light is interrupted by the ultraviolet light absorbing layer 4, whereby the deterioration of the thermal recording layer 3 is also prevented.

Title: Brake control system for preventing wheel-locking
Inventor: IIZAWA TAKAHARU
IPC: B60T8/1761
Filed: 1983-04-18
Abstract: PURPOSE:To eliminate a delay in the timing of pressure-reducing, by resetting a reference wheel speed if the difference between a set reference wheel speed and a wheel speed reaches the second wheel speed threshold value before it reaches the first wheel speed threshold value at which the control of pressure-reducing is initiated. CONSTITUTION:If the deceleration exceeds a threshold value at a sampling time (a1), the wheel speed VP at this time is set as a reference wheel speed Vs. Thereafter both wheel speeds are compared with each other, and if the wheel speed exceeds the reference wheel speed at a time a3, the wheel speed at the time a3 is again reset as the reference wheel speed Vs. Further, since the wheel speed exceeds also at the time a4, the reference wheel speed Vs is again set. Subsequently, with the similar steps the reference wheel speed is successively reset so that the reference wheel speed is properly set at a time which is substantially the same as the time when the deceleration due to braking reaches the threshold value, thereby the decreasing operation of braking pressure may be surely made at the time a18.
