Title: Battery box
Inventor: KITAMURA KEIICHI
IPC: H01M2/10
Filed: 1995-05-29
Abstract: PURPOSE: To prevent a battery from springing out at the time when storing a plurality of batteries in one row and store batteries stably. CONSTITUTION: In a terminal installation part 22, a battery terminal 10 is pushed in a groove part (supporting parts 25a, 25b) and at the same time the center part 12c of a positive connection part 12 is engaged with a stopper 26. Consequently, the positive connection part 12 of the battery terminal 10 is set in a state wherein the part 12 is slightly pushed in the longitudinal direction (the forward side of this face) of the battery 1 in the contact part of ribs 24a, 24b. That is, the battery terminal 10 inclines in the direction in which the upper side part (side parts 12a, 12b) of the positive connection part 12 is made narrower than the lower side part (the center part 12c) to the longitudinal direction of the battery 1.  As a result, in the case the battery 1 is stored in a battery storage part 17, the positive pole 1a is electrically connected by being brought into contact with the tilting positive connection part 12 at two points (R, S) and at the same time due to the inclination, the positive pole is prevented from moving upward side of the battery 1.

Title: Humidity detecting circuit
Inventor: UEKI TOYOAKI
IPC: G01N27/04
Filed: 1983-08-24
Abstract: PURPOSE:To adjust an error due to variance among ceramic humidity sensor by composing a rectifying circuit with an absolute value circuit of a high-input impedance type and a smoothing circuit. CONSTITUTION:A sensor 5 changes variation in relative humidity into variation in resistance. A resistance-voltage converting circuit 2 outputs an AC voltage corresponding to the variation in relative humidity, and the voltage is converted by a rectifying citcuit 3 into a humidity detection signal, i.e. DC voltage. The rectifying circuit 3 consists of the absolute value circuit 31 and smoothing circuit 32, and the absolute value circuit is a high input impedance type, so the resistance in the resistance-voltage converting circuit 2 is increased in value. Therefore, even if the sensor 5 has variance, an adjustment corresponding to it is made.

Abstract: PURPOSE: To make it possible to connect and disconnect a power supply without providing an independent controller to each compound system, by connecting a power controller to a single system and a compound system.  
     CONSTITUTION: When either start or stop signal is inputted from receiver circuits 30 or 31, control circuit 33 operates to input a clock signal from originating circuit 32, and consequently control circuit 35 is operated to apply an output signal to drive circuit 36, so that circuit 36 will transfer a start or stop signal to a post-stage power controller.

Due to the switching of the transistor 26, alternating voltage develops in each winding of a preheating transformer 27, and preheating electrodes 7f1 and 7f2 are preheated by voltage produced in filament windings 27f1 and 27f2. Immediately after the preheating period (T3), the output of a preheating-time setting circuit 21 is cut out, and the preheating circuit 23 stops working. As a result, the electrodes 7f1 and 7f2 are preheated during the period (T3) between the phase (theta2) and the phase (theta5).

Abstract: PROBLEM TO BE SOLVED: To obtain the fire sensor with high precision which could not be obtained by the detection of only information regarding a secondary phenomenon by processing image data picked up by an image pickup part having the detection area of a secondary information detecting device in its detection area. SOLUTION: If a fire takes place in the detection area of a temperature sensor 3 of the secondary information detecting device 101, the temperature rises, so the temperature sensor 3 operates and sends a detection signal to a control part 4. On receiving this detection signal, the control part 4 sends an image pickup start signal to the image pickup part 1. By receiving the image pickup start signal, the image pickup part 1 starts picking up an image of the image pickup area and sends an image output ready signal to the control part 4 when becoming able to output the picked-up image data. The control part 4 receives the image output ready signal and sends an image process start signal to an image process part 2.  Once receiving the image process start signal, the image process part 2 receives the image data outputted from the image pickup part 1 and performs a fire deciding process for deciding whether or not there is a fire in the obtained image.
