Title: Delayed sweep circuit
Inventor: NAGATOMO SHIGEYUKI
IPC: G01R13/20
Filed: 1990-08-29
Abstract: PURPOSE:To generate equivalent sampling pulses equal to uniformly dividing an optional period into N (integer of two or above) by automatically controlling the inclination of the saw-toothed voltage and the increase step voltage in response to the period of an input trigger signal. CONSTITUTION:An inclination section is formed on the saw-toothed voltage V1 generated by a sawtooth wave generating means 20 starting with the time t0 of the first timing signal Q1, and the inclination of the inclination selection is controlled so that a reference signal VS is obtained at the time of the second timing signal Q2 when nT elapses from the time t0 by the first control loop 30, where (n) is a natural number and T is one period of a trigger signal TG. A step wave generating means 14 generates the step voltage VST ascending or descending by an increase step of 1/nN voltage VS for each output sampling pulse SP. The voltage V1 and voltage VST are compared 13, a pulse generating circuit 15 is triggered by its comparison output to form the SP. The equivalent SP equal to uniformly dividing one period of the signal TG is invariably obtained by the control loop 30 even if the frequency of the signal TG is changed.

Filed: 1997-08-25
Abstract: PROBLEM TO BE SOLVED: To accommodate a clamp at a position which does not disturb cargo handling work by making a clamp swingable between a clamp position where products are held and a accommodating position where the clamp is stored in a support frame through an opening formed in the support frame. SOLUTION: When a cylinder mechanism 10 is expansively contractively operated, a clamp 12 is rocked around a rocking shaft 8 provided at the lower part of a support frame 6, through an opening 7 in the support frame 6, arbitrarily from a position shown by a solid line X through a position shown by a two-dot chain line Y to a position shown by a two-dot chain line Z.

Title: Objective lens driver
Inventor: ISHII HIROKAZU
IPC: G11B7/09
Filed: 1983-12-02
Abstract: PURPOSE:To obtain an objective lens driver which has a large damping effect and also a satisfactorily high frequency of a secondary resonance mode, by using parallel plate springs having a large spring coefficient at their center parts. CONSTITUTION:An objective lens 1, a condenser lens 13, a columnar lens 14 and a 4-split photodetecting element 15 are held by a holding member 2 which is supported by a device main body 6 by means of tracking parallel plate springs 4 and 5 and focusing parallel plate springs 11 and 12. Each of these plate springs has folded parts 40 and 41 at its center part to improve the rigidity and to increase the spring coefficient. At the same time, damping members 31 and 32 are attached at both end parts of the spring where the spring coefficients are small. In such a way, the damping effect is improved to both the primary and secondary resonances since the damping members are attached at both end parts of a spring where the spring coefficients are small. Furthermore, the weight of the spring can be sufficiently reduced and therefore the secondary resonance frequency is never reduced.

Title: Solar heat electric power generation apparatus
Inventor: TSUKAMOTO MORIAKI
IPC: F24S90/00
Filed: 1983-12-07
Abstract: PURPOSE:To enable to stably generate electric power even under the change of insolation without making a heat storage tank and a heat accumulator larger by a method wherein a heat exchange piping to transfer the heat of the heat accumulator to the heat storage tank is provided in order to transfer the heat of the heat accumulator to the heat storage tank. CONSTITUTION:When the heat energy collected at a heat collector for superheating 4 is larger than the heat quantity necessary for superheating steam, the water passing through a heat exchange piping 6, which is provided between a heat accumulator 2 and a heat piping 6, which is provided between a heat accumulator 2 and a heat storage tank 1, is sent by means of a pump 9 so as to be heated at the heat accumulator 2 and sent to the heat storage tank 1 in order to transfer the heat of the heat accumulator to the heat storage tank 1, resulting in utilizing the heat collected at the heat collector for superheating. On the other hand, when the insolation becomes smaller, the quantity of steam generated at a heat collector for evaporation 3 becomes also smaller and the shortage of the steam quantity necessary for power generation is covered with the steam transferred from the heat storage tank 1 and the abrupt lowering of the temperature of the heat storage tank 1 is resulted. Because the heat is exchanged from the heat accumulator 2 to the heat storage tank 1 as mentioned above, the time to allow the continuous operation of the titled set is prolonged and the quantity of power generated is enlarged, resulting in enabling to continue the stable power generation even when the insolation amount changes, without making the heat storage tank and the heat accumulator larger.
