Title: Capacity deterioration detecting method for circulating pump in hot-water boiler
Inventor: TAI SEIJI
IPC: F24H1/18
Filed: 1992-06-17
Abstract: PURPOSE:To detect the abnormal stopping or the deterioration of capacity of a circulating pump by a method wherein the output of a first temperature detector for the auxiliary or main control of a combustion device, the output hot-water temperature of a heat exchanger or a second temperature detector for main or auxiliary control are employed. CONSTITUTION:When an ON signal is outputted to a combustion device 2, a first temperature detector 16 and a second temperature detector 17 are decided whether is there any trouble such as wire disconnection or the like or not. When it is decided YES, it is decided that T1-T2 T is sutisfied or not. T1 is a heat medium water temperature in the upper part of a boiler body 1, T2 is the hot-water temperature at the outlet port side of the heat exchanger 6 and Tx is a temperature set in a control unit. When a combustion device 2 is being operated and a circulating pump 5 is stopped, a heat medium water temperature is high and a water temperature at the outlet port of the heat exchanger becomes low. Accordingly, it is decided as YES. Then, a count is started by a softwear timer and a predetermined time is decided whether a predetermined time has elapsed or not. When it is decided YES in this case, data is stored as the abnormality of the circulating pump 5.

Title: Spectacles-less stereoscopic video projector
Inventor: TAKEUCHI KOICHI
IPC: G03B35/24
Filed: 1987-07-25
Abstract: PURPOSE:To obtain personal stereoscopic videos which are free from chromatic aberrations and band-shaped fringes by a lenticular by placing two units of projectors near an observer's head and projecting the videos toward a beads screen. CONSTITUTION:The video projected from the miniature projector 2L is reflected by the beads screen 3 and returns to the projector in the form of a light beam having a width of a range 4L. The video projected from the miniature projector 2R returns in the form of the light beam having the width of a range 4R. As a result, the observer's left eye views the light of the range 4L and the right eye views the light of the range 4R and the observer is thus capable of viewing the stereoscopic images. The movement of the observer's head is thereby enabled. The spectacles-less comfortable stereoscopic projector which obviates the generation of the chromatic aberrations and band-shaped fringes is thus obtd.

Title: Direct-current regulated power source
Inventor: TATSUMI KENICHI
IPC: G05F1/10
Filed: 1980-12-26
Abstract: PURPOSE:To lower an operating voltage, to increase sensitivity, and to eliminate malfunction by using a rectangular-wave voltage, which synchronizes with an AC power voltage, and an AND output of voltages, which have a phase difference, for a trigger signal for a triac. CONSTITUTION:A rectangular-wave voltage which synchronizes with an AC power voltage are applied between the power supply terminals 12a and 12b of Schmitt circuits 10a and 10b to supply the terminal voltage Ec of a capacitor C, which has a phase and amplitude determined by a comparison difference voltage between a DC voltage Eo and a reference voltage Es, between input terminals 11a and 11b. Therefore, the circuits 10a and 10b operate only during a period when the rectangular-wave voltage is applied, and its output voltage is inputted as a trigger signal to the control terminal of a triac 2. Then when the voltage Eo drops below the Es, the comparison difference voltage rises to increase the quantity of light from an LED7, and the current of a phototransistor 15 increases to decrease the phase difference between the voltages Ec and E, thereby increasing its output. Namely, the conduction angle of the triac is controlled so that the voltages Eo and Es become equal to each other, thus stabilizing the voltage Eo.

Title: Electrolyte for lithium battery
Inventor: HIRAI TOSHIRO
IPC: H01M10/0567
Filed: 1987-07-27
Abstract: PURPOSE:To increase the conductivity of an electrolyte and the chargedischarge performance of a lithium electrode by containing a specified concentration range of straight-chain alkane in a solution prepared by dissolving a lithium salt in an organic solvent. CONSTITUTION:Straight-chain alkane is contained in a concentration range of 10<-3>-10<-1>M(mole/l) in a solution prepared by dissolving a lithium salt in an organic solvent, and this solution is used as an electrolyte. The straight-chain alkane is easily adsorbed on a lithium negative electrode without disturbing the dissociation of a lithium salt and the transfer of a lithium ion, and retards the reaction of lithium with a solvent. The deposition of lithium on a negative electrode and its dissolution into the electrolyte attendant on charge-discharge are smoothly performed. The conductivity of the electrolyte and the charge- discharge performance of the lithium electrode are therefore increased.
