Title: Fire alarm device
Inventor: HAYAKAWA DAISHIROU
IPC: G08B17/06
Filed: 1978-05-17
Abstract: PURPOSE: To obtain a fire alarm which features the steady operation and more economical structure than those of other systems by applying such system that the pyrocurrent of the PCM piezoelectric ceramic plate is charged to the capacitor to actuate the switching circuit.  
     CONSTITUTION: When the pyrocurrent of PCM piezoelectric ceramic plate 1 is charged to capacitor C and the potential of circuit connection point A increases up to the level corresponding to the fixed temperature, programable unijunction transistor PUT is turned on to increase the potential of circuit connection point B. As a result, the SCR is turned on to actuate oscillator circuit 8 and then to ring electronic buzzer 9. The fine adjustment is possible easily via the variable resistance of resistance R 6  or the like. In such constitution, the steady operation is ensured. Furthermore, the heat resistance is high since the piezoelectric ceramic plate is an inorganic material, and also the price can be reduced down to 1/2W1/5 compared with the thermistor or the high molecular film.

Title: Firearms controller
Inventor: HAYAKAWA HIDEO
IPC: G01S13/66
Filed: 1985-03-25
Abstract: PURPOSE:To improve the hit accuracy by controlling the observation interval according to the desired accuracy decided by a deciding means for guidance command accuracy to calculate the guidance command from the target tracking information obtained from said control of the observed distance and transmitting this obtained command to a missile. CONSTITUTION:For a firearms control computer 20, the command accuracy deciding job is started when the command calculation is through with a missile or the program execution is started in a fixed time rate. Thus the accuracy needed for the command is decided from the relation between a target and the missile. For instance, the high accuracy is required for a missile guidance command in case a missile 9a flying toward a target 8a is at the final stage of guidance. While a missile 9c flying toward a target 8c does not need the high accuracy since it is at an early stage of guidance. Therefore an observation interval is calculated to attain said levels of accuracy. Based on this calculated interval, the scanning direction of an antenna beam is calculated. Then a beam scan indication is sent to a phased array antenna.

IPC: D06F33/00
Filed: 1978-05-22
Abstract: PURPOSE: To save water rationally by determining operation time on basis of water supply time and by installing a timer device which calculates and processes in accordance with different water temperature modes.  
     CONSTITUTION: Each water supply time T is measured and memorezed in accordance with supply modes such as water, hot water, and the mixture. If the supply of water is not completed within the set time limit To, the operation is stopped as a failure. Then, water supply time T is multiplied by a constant experimentally obtained from water temperature mode, and calculated by ALU section and the result is memorized by RAM. Rinsing time is determined in accordance with this calculated value and rinsing extent. In case this time is too short, preliminary rinsing is done before flood rinsing. From the above processing, the time of preliminary rinsing, flood rinsing and shower dehydrating is set at RAM. In this case, correction is made by using the figure 0.5 times more for hot water only and 2 times more for the mixture than water only.

IPC: H04N1/40
Filed: 1988-03-16
Abstract: PURPOSE:To reduce the scale of a circuit by providing a memory which stores a diffusion error table for an error diffusing method or a dither matrix table so as to correspond to a selected mode, and an enable circuit which adds distribution error corresponding to a memory output to picture data in the case that the selected mode is the error diffusing method. CONSTITUTION:In the circuit constitution of the error diffusing method, the objective picture data to be binarized is converted into a binary value by a single prescribed threshold value by a comparator 18. At that time, picture element density is inputted as an address to the memory 25, and corresponding output data is distributed as an error to peripheral picture elements, but in this case, diffusion error data is stored previously in the memory 25. Besides, in the circuit constitution by a dither method switched by a first and a second selectors 20, 21 and the enable circuit 19, all distribution errors to the peripheral picture elements are made to be zero, and the address for a dither matrix is inputted as the address to the memory 25, and the picture element data is binarized by the comparator 18 as considering the corresponding output data to be the threshold value. In this case, the dither matrix is stored previously in the memory 25, and accordingly, a storage circuit can be shared in common. Thus, the scale of the storage circuit can be reduced.

Title: Phase-difference supervisory circuit
Inventor: NOGUCHI OSAMU
IPC: G01R25/00
Filed: 1986-03-20
Abstract: PURPOSE:To effect proper processing of a signal-processing circuit, by supervising a phase-difference condition between 2 synchronous signals of non- synchronization and of nearly the same frequency by comparing member, selector, counter and identifying circuit. CONSTITUTION:A primary reset signal S5 is introduced into FF67 and FF71 of a terminal set S respectively and the primary setting of a phase-difference flag signal FLG is conducted. And, when a time-difference (t) of 2 synchronous pulse signals CP1, CP2 of the non-synchronized and similar frequency are longer than a supervisory time T1, a FLG signal from an identifying circuit turns out to be 0. Further, when the time-difference (t) of CP1 and CP2 is shorter than the supervisory time T1 with arrival of a signal S2 during the time T1, the FLG signal from a circuit 66 is located at 1 and a selector 65 selects a supervisory time T2 (however, T1<T2). Thus, when the time T2 is selected as the supervisory time, if the time difference (t) continues to be shorter than the time T2, the FLG signal from the circuit 66 continues 1. Further, if the time t becomes longer than the time T2, the FLG signal indicates (0) and the selector 65 selects the supervisory time T1.
