Title: Belt conveyor
Inventor: IMAI KAZUHISA
IPC: B65G41/00
Filed: 1984-12-30
Abstract: PURPOSE:To transoort the transported articles safely and certainly by installing pulleys on the both sides of an expandable conveyor frame from the opposed side plates and laying a belt inside the frame, thus obtaining a conveyor having the length corresponding to the place of use. CONSTITUTION:A frame 1 is formed by installing an expandable conveyor frame 3 formed from the side plates 9 and 9 opposed so as to hold the right and left side plates 5 and 5 of a main conveyor frame 2 in slidable ways in the longitudinal direction so that the installation position can be adjusted, for the main conveyor frame 2 formed from the side plates 5 and 5 opposed at right and left. Since pulleys 4 and 4 for laying a belt are installed at the both side positions, the conveyor belt having the length corresponding to the position of use can be easily obtained by adjusting the installation position for the main conveyor frame 2 of the expandable conveyor frame 3 according to the necessary length of the installation position such as the part between the working apparatuses. Further, since a belt 23 is laid inside the frame 1, transported articles can be held free from drop, and can be transported safely and certainly.

Title: Petroleum heater
Inventor: ARAKI TAKASHI
IPC: F24C5/00
Filed: 1998-10-02
Abstract: PROBLEM TO BE SOLVED: To improve safety by suppressing or stopping combustion when a top plate is closed with any object in a petroleum heater such as a petroleum radiation heater or a petroleum fan heater for exhausting combustion heat generated in a burner upward from the top plate. SOLUTION: When top surface temperature is raized not lower than first temperature (for instance, 80 deg.C), combustion is lowered (step S2). When this top surface temperature is lowered to temperature not higher than reset temperature (for instance, 40 deg.C), the combustion is returned to the original combustion (S4). When the top surface temperature reaches second temperature (for instance 120 deg.C) hither than the first temperature, the combustion is stopped (step S6). Thus, when the top plate is closed to block exhaust heat, a combustion power is reduced to suppress the rise of the top surface temperature. In case of insufficiency, the combustion is stopped to further suppress the rise of the top surface temperature.

Title: Light source lighting apparatus for single beam spectroscope
Inventor: KUWATA KOJI
IPC: G01N21/25
Filed: 1984-12-27
Abstract: PURPOSE:To remove variations in the brightness of a light source, by detecting variations in the brightness of the light source with a photoelectric detector for monitoring to perform a constant current control of a load current based on a comparison deviation signal in comparison of the output thereof with a reference voltage. CONSTITUTION:The brightness of a light source 1 is detected with a photoelectric detector 5 for monitoring and the brightness signal via a photoelectric conversion is inputted into a CPU8 as digital brightness detection signal VX by way of an amplifier 6 and A/D converter 7 to be taken into an RAM9 in succession. The brightness detection signal VX is compared with the reference value VS to determine whether VX>VS or not. The difference (VS-VD1) between the reference value VS and the deviation output VD1 is outputted. It is so controlled that when the brightness of the light source 1 increases (VD1>0), the current flowing through a transistor 3 is reduced and when the brightness of the light source 1 decreases (VD1<0), the current flowing through the transistor 3 is increased.

Title: Power steering
Inventor: WATANABE KOICHI
IPC: B62D5/08
Filed: 1996-10-02
Abstract: PROBLEM TO BE SOLVED: To change a tire steering angle without changing a steering wheel angle by connecting planetary gears of input-output side gear mechanism with the same gear ratio to each other by a carrier, and controlling assist force in response to the rotation of the internal gear of the input side gear mechanism so as to fix or rotate the internal gear of the output side gear mechanism. SOLUTION: When a steering wheel H is steered, the rotation of an output shaft 3 is impeded by grounding resistance of tires (t), and input and output shafts 1 3 are relatively rotated so as to generate rotational difference between sun gears 9, 12 of input-output side gear machanisms A, B. Planetary gears 11, 14 are connected by a carrier 15, and the revolution of the planetary gear 11 is impeded by rotational difference. The planetary gear 11 is autorotated around the carrier 15 as an axis by that portion, and an internal gear 10 is rotated. A lever 16 therefore switches a spool 17 to impart assist force to steering of the tires (t). When a selector valve 28 is switched, a movable body 23 moves due to pressure difference, and the internal gear 13 is rotated by a specified angle by a lever 22.  In response to this, autorotation of the planetary gear 11 is assisted and negated to change the turning angle of the internal gear 10, thus changing assist force.
