Title: Temperature control method of semiconductor laser of optical scanning device
Inventor: TOMITA SATORU
IPC: H01S5/068
Filed: 1984-07-11
Abstract: PURPOSE:To make a stable optical scan by setting set temperature for temperature control according to the time difference between output signals generated by two photodetecting elements. CONSTITUTION:Outputs of the photodetecting elements 34 and 36 are impressed to comparators 56 and 58 through a flip-flop 46, counter 50, D/A converter 52, and amplifier 54. The comparator 56 outputs a logical value 0 when the time difference tau between the outputs of the photodetecting elements 34 and 36 is larger than a set value tauB and outputs a logical value 1 when not. A comparator 58, on the other hand, outputs a logical value 0 when the time difference tau is smaller than tauA or a logical value 1 when not. Consequently, difference signals are impressed to a temperature setting circuit 64 according to respective cases of tauA< tau<tauB, tau>tauB, and tau<tauA; when tau>tauB (tau>tauA), the temperature setting circuit 64 sets a value corresponding to temperature which is specific value higher or lower than the current set temperature in a comparator 66.

Title: Short arc discharge lamp
Inventor: MORI YASUKI
IPC: H01J61/073
Filed: 1987-06-11
Abstract: PURPOSE:To upgrade a heat-radiating effect and to prevent cracks from occurring at a sealed part and to make this lamp large-powered and small-sized, by performing rough-surface processing on a part of an anode sealed protruding inside a lamp bulb. CONSTITUTION:In a sealed part 1a of a lamp bulb 1 made of quartz, a base end part 2a of an anode 2 made of tungsten is connected to an external introduction wire 4 by an electrical method, with airtight sealing metallic foil 3 of molybdenum or the like in between. A xenon gas is sealed in the bulb 1. A surface of a protruding part 26 of the anode, where a getter 5 for use in suction of impure gases is mounted, is provided with rough processing 6 by the use of a sand blast method or the like. Accordingly, a heat-radiating effect can be upgraded by a simple method without enlarging the anode and the sealed part and also without forming a groove on a surface of the anode. Further the amount of high temperature, caused by the lighting of the lamp, being conveyed to the base end part 2a is reduced to avoid such a trouble that a glass of the sealed part 1a is cracked and soon broken.

Filed: 1986-06-20
Abstract: PURPOSE:To enable the easy control for restricting the speed of an automobile running an extremely slow speed by providing a means for detecting the return operation of an accelerator pedal after being stepped down and shifting a clutch toward an OFF position on the basis of the detection of the return operation. CONSTITUTION:When the stepping extent of an accelerator pedal 17 is small, it is judged that the pedal 17 is being released. Or it is judged that the speed of an automobile is being restricted against excessive speed in putting the automobile in and out of a garage and against other driving conditions. Then, when the releasing of the pedal 17 has exceeded a predetermined level, the stepping amount thereof is memorized. Thereafter, a control device 23 reads clutch operation speed and position corresponding to the stepping amount, from a map and returns a clutch to a predetermined position at a predetermined speed via the control of an electromagnetic feed valve 15. According to the aforesaid constitution, the speed of the automobile can be easily reduced to a desired value simply by returning the pedal 17 to the idling side.

IPC: G02B5/00
Filed: 1982-08-19
Abstract: PURPOSE:To make an optical switch strong to oscillation and to make the adjustment of a prism movable base easy by so arranging the optical switch that the driving bar of a plunger and the movable based are brought into contact with other by magnetic force and the movable base movs according to the movement of a movable iron core. CONSTITUTION:A prism movable base 16 mounted with a prism 17 is provided internally with a permanent magnet and is provided with iron cores 20 on both sides. The base 16 is supported freely slidably to a stationary base 15 having a guide groove with a cover and the cores 20 are attracted to the end face of a driving bar 18 by means of a permanent magnet 19. The bar 18 and the base 16 move according to the movement of an iron core 10. The bar 18 and the base 16 are brought into contact with each other merely by magnetic force and are not fixed and therefore there is a degree of freedom freely slidable in parallel with the contact surfaces thereof. The respective movements are thus made smooth. Since the base 16 and the bar 18 are in contact with each other, the attraction force is strong and the optical switch is strong to oscillation. The optical switch is thus made strong to oscillation and the adjustment of the movable base is made easy.

Title: Indirect type hydraulic elevator
Inventor: ITO MITSUO
IPC: B66B7/12
Filed: 1995-06-12
Abstract: PURPOSE: To allow the operator to know the marginal dimension for thrusting-up by sensing the change in the distance from the upper part of a cylinder to a plunger stopper, and indicating the value obtained by subtracting the distance change from the marginal dimension in the initial state. CONSTITUTION: If a main rope 4 elongates from the initial state according to the initial period elongation or secular change, an expansion rod of a sensing device 12 is intruded by a plunger stopper 3a before an elevator car 1 reaches the uppermost story floor surface. The intrusive displacement of the rod is converted into voltage by a transducer and fed to an elevator control part 16. The control part 16 calculates this as the moving distance of a plunger 3. Because the marginal dimension A for thrusting-up of the plunger 3 was a specified max. value in the initial state, the value obtained by subtracting the plunger moving distance calculated by the control part 16 from this max. value is indicated as the change in the marginal dimension for thrusting-up of the plunger 3 caused by the elongation of the main rope 4.

Title: Electronic equipment containing power supply cut-off processing function
Inventor: TANAKA MASATO
IPC: H01J9/22
Filed: 1990-05-31
Abstract: PURPOSE:To surely perform the end processing with an electronic equipment containing a power supply cut-off processing function by cutting off a power supply after carrying out automatically the processing to be done right before the cut-off of the power supply set previously when an operator gives an instruction for cut-off of the power supply by means of an instruction means. CONSTITUTION:A CPU 1 always checks whether a power switch is kept OFF or not. If so, the end procedure to be carried out right before the cut-off of a power supply is read into a main memory 9 through the head of an end procedure register file of a hard disk 7 and via a disk controller 6. This operation is repeated. When all end procedures stored in a register file are carried out, a power cut-off instruction is outputted to a power circuit 3. Thus the circuit 3 cuts off the power supply. As a result, the read-out and execution of the end procedures and even the cut-off of the power supply are automatically carried out under the control of the CPU 1 when the power switch is turned off.
