Title: Brake holding device for car
Inventor: KUWANA KAZUTAKA
IPC: B60T11/28
Filed: 1983-05-06
Abstract: PURPOSE:To improve the response and the speed of control when the holding of brake is released by prohibiting the brake holding when the inclination at the time of low speed direction change is over a fixed angle for repeating holding and releasing of the brake several times within a short time. CONSTITUTION:When a car is stopped by a brake operation, a car speed detector VD does not output, so that a NAND-Gate NA2 becomes L, a transistor Q3 is off, and a driver DRV is magnetized by an electric coil 123 to hold the brake. At the time of sudden brake, the output of a car speed change detecting circuit becomes H and flip-flop circuits NA3 and NA4 are not set so that the brake is not held. When an acceleration pedal is stepped in with the brake being held, a contact of a switch SW2 is opened, the transistor Q7 in on, and the output of an NOR Gate NR1 becomes a reverse signal of an output-fold of a pulse generating circuit OSC2. In this way, a transistor Q8 repeats ON and OFF within a short time. Consequently, the coil 123 repeats to be switched on and off, and the brake is gradually released.

Title: Luminance measuring method and luminance measuring device
Inventor: NAKAZAWA TEN
IPC: G01J1/42
Filed: 1994-03-26
Abstract: PURPOSE:To dispense with a dark room and enable stable luminance measurement of even a low luminance emitter by using a solar cell as a luminance measuring element, and measuring luminance from the current value outputted from the solar cell. CONSTITUTION:A solar cell 21 receiving light from a light measured emitter 1 outputs a current proportional to the light receiving quantity by photoelectric effect. Since this current can be confirmed by a current measuring device 3, if the correlation between the current value and luminance is previously obtained, the luminance can be measured as it is, but the current is converted into voltage by a converter 4 because of the difficulty in successive electrical handling. The voltage value is measured by a voltage measuring apparatus 5, and the luminance can be measured by the correlation to luminance. In addition, light intercepting material 23 is provided at the outer periphery of the solar cell 21 so as to prevent external light from entering between the emitter 1 and the light receiving face of the solar cell 21. Luminance can be thereby measured at any place without being influenced by the surroundings, without needing a dark room.
