IPC: G04B19/30
Filed: 1977-12-29
Abstract: PURPOSE:To prevent the occurrence of malfunction of the watch driving circuit by operating the watch driving circuit with the current having been charged in a capacitor during lighting of lamp. CONSTITUTION:When a lamp 10 is lighted by closing the switch 1 of a lamp lighting circuit 3, a transmission gate circuit 4 goes OFF and a watch driving circuit 7 is driven by the discharge current of a capacitor 6.

Title: Heating cooker
Inventor: HIRAI KIYOSUMI
IPC: F24C15/20
Filed: 1983-08-31
Abstract: PURPOSE:To hold a whole temperature, including the temperature of a gas device placed on a top plate, at a reduced value, by a method wherein the air around a heating chamber is covered with a casing, and the circumference of a chimney is covered so as to serve as the extension of the casing to form an exhaust cylinder through which the heated air is exhausted. CONSTITUTION:Separately from a main waste gas port 25, an auxilairy waste gas passage 30 is communicated with an upper surface wall 24 of a heating chamber 23. When a device is used as a gas heater, a part of hot blast waste gas in the heating chamber 23 passes through th auxiliary waste gas passage 30, and when the device is used as an electronic oven, the air, which cooled a magnetron 34, passes in a condition to contain steam produced from an object to be heated, not shown. Since exhaust gas in the heating chamber is collected in one place and is exhausted through an exhaust duct from an exhaust cylinder, a high temperature is hard to leak to the outside, and this enables a device to be held at a low temperature. Hot blast around the heating chamber and the air, which cooled the magnetron, are gathered and exhausted from an exhaust port through the circumferences of the exhust cylinder, resulting in prevention of leak of a secondary high temperature and in maintenance of the device at a ow temperature.

More definitely, the map indicating the pressure reducing time T for the deceleration Ralpha is stored in a control force distributing controller 15, and the pressure reducing time T corresponding to the calculated deceleration difference Ralpha is read therefrom. The pressure reducing time T is increased with the third ratio according to the increase after the deceleration difference Ralpha exceeds the specified value Ralpha1, and the pressure reducing time has the characteristic that it is increased with the small fourth ratio than the third ratio when the deceleration further exceeds the specified value Ralpha2.

IPC: G01P21/00
Filed: 1983-08-31
Abstract: PURPOSE:To obtain a converter where the number of pulses in a certain time is selected freely to obtain required high precision and resolution, by generating a pulse whose polarity is equal to that of the output of a positive/negative discriminating means of the motion of a dynamic system, and intervals are a time shorter than the oscillation period of the dynamic system, and controlling the positive/negative time of dynamic feedback in proportion to the difference between the number of positive pulses and that of negative pulses in this oscilation period. CONSTITUTION:A sampling circuit 6 performs sampling with clocks having a period tau shorter than an oscillation period T of a pendulum 1 and generates considerably many pulses in its output e2. These pulses e2 are sent to a counter 8 simultaneously with outputting. The counter 8 is reset at intervals of T seconds when the oscillation period of the pendulum 1 is T seconds, and a difference (i-j) between a number (i) of positive pulses and a number (j) of negative pulses of pulses e2 in the set period is outputted to a feedback current generating circuit 9. If the value (i-j) is positive, the time of a feedback torque is made shorter by a time (i-j)tau'; but if it is negative, the time of the feedback torque is made longer by the same time.
