Title: Camera with backup power source device
Inventor: SAWADA MASARU
IPC: G03B17/24
Filed: 1995-04-13
Abstract: PURPOSE: To prevent a timer circuit backup auxiliary battery from being expired even in the case a main battery is not loaded for a long time. CONSTITUTION: The main battery 30 and the timer circuit backup auxiliary battery 32 are connected to the timer circuit 20 through a battery supply switch 34 which is opened/closed according to a control signal from a control circuit 12, so that power is supplied. A battery detection switch 42 detecting the presence or absence of the main battery 30 is connected to the control circuit 12. When the main battery 30 is pulled out from a camera, a battery detection switch 42 is turned on. In the case an on-signal generating state is continued for a specified time, the control circuit 12 opens a battery supply switch 42 and inhibits power supply from the battery 32. Even in the case the main battery 30 is not loaded for a long time, the battery 32 is prevented from being expired because of driving the timer circuit 20.

Abstract: PROBLEM TO BE SOLVED: To obtain stable response characteristics and performance at all times by executing adaptive control to ensure that the response characteristics of each work machine accord with those of a reference model and providing an adaptive control means which corrects a control command value for the amount of pressure oil supplied to each work machine. SOLUTION: The speed component in the X and Y directions of the head point of an arm is commanded and a speed command signal is entered into a coordinate transforming section 11 in a speed command section 10, and a speed command at the head point is coordinately transformed to the angular command of a boom and the angular speed command of an arm at a coordinate transforming section 11. Then, each output of the coordinate transforming section 11 is entered into a boom flow rate control system 20 and an arm flow rate control system 30, respectively.  Then stable performance can be obtained in a hydraulic shovel whose characteristics fluctuate greatly by executing control to correct command values to the flow rate control systems 10, 20 with adaptive controllers 26, 36 so that the output of the boom control characteristics and the arm control characteristics may accord with that of the reference model using model reference adaptive control and having desirable dynamic characteristics.

Title: Button type alkaline battery
Inventor: KOGURE HARUO
IPC: H01M6/12
Filed: 1984-05-02
Abstract: PURPOSE:To obtain a battery with good low discharging performance by specifying the ratio of electric capacity between the positive electrode and the negative electrode. CONSTITUTION:In an alkaline battery using manganese dioxide as active material of the positive electrode 7 and zinc as active material of the negative electrode 4, the ratio of electric capacity between the positive electrode 7 and the negative electrode 4 (negative electrode capacity/positive electrode capacity) is in the range from 1.0 to 1.3. Thus, as the amount of the active material of the negative electrode increases, its low discharging performance can be remarkably improved. Though, in general, the ratio of electric capacity more than 1.0 causes the problem of generation of gaseous hydrogen from the negative electrode, an alkali-manganese battery does not cause such a problem specifically until the capacity ratio reaches 1.3.

Title: Speaker diaphragm
Inventor: YAMAMOTO TOORU
IPC: H04R7/02
Filed: 1981-06-10
Abstract: PURPOSE:To realize the physical properties including a light weight, a high specific modulus of elasticity and a high internal loss respectively at the same time and to allow the continuous molding for a speaker diaphragm, by mixing the flake reinforcing material into the base material of the thermoplastic synthetic pulp. CONSTITUTION:The thermoplastic synthetic pulp is mixed with the flake substance and machined 1. As a result, a large number of air layers are contained in a mixed sheet. These air layers are maintained even after the heating and molding processes. Accordingly the density is low with a reduced weight for the final diaphragm sheet to allow a continuous process. Furthermore the synthetic pulp is formed into a film owing to a heating process. During the heating process, the base material of the synthetic pulp and the flake substance are fused by the heat to increase the reinforcement effect for a reinforced material. The high specific mudulus of elasticity is also increased. Both the modulus of elasticity and the internal loss can be increased by setting the content of the flake material at about 5-30wt%

Thereafter, the ray is condensed into a transmission line 8 of an optical fiber through an optical lens 6, and it is transmitted to a next station. On the other hand, an optical signal of wavelength lambda1 transmitted from a station at a preceding stage, is transmitted through a transmission line 9 of an optical fiber, and it is irradiated for the lens 6. Then, it turns into parallel rays, and its ray arrives at the grating 7. Whereby, it is diffracted by an angle of diffraction, which is proper for wavelength lambda1, and its optical path is altered. The parallel rays altered arrive at the lens 5, and are condensed into a photodetector 12.

Abstract: PURPOSE: To attain a high-speed elevator system smooth, quiet and improved in comfortableness. CONSTITUTION: Air deflectors 31, 36 are mounted on the top and bottom of a counterweight assembly in an elevator system to deflect air in an elevator hoistway to the sides of a counterweight 2 as the counterweight 2 moves up and down in the hoistway.

A quieter and smoother passenger ride is thus accomplished. In an ultra high-speed elevator system, the counterweights are completely enclosed in an aerodynamic jacket. Cable connections and compensating rope connections to the counterweight are all made inboard thereof to ensure that the counterweight is free of turbulence-inducing protuberances.
