Title: Stroboscope device
Inventor: SHIMADA YOSHINAO
IPC: H05B41/32
Filed: 1997-09-09
Abstract: PROBLEM TO BE SOLVED: To shorten the charge time of a main capacitor while restricting the rush current by relatively shortening the pulse cycle of the stroboscopic pulse signal for driving a charging transformer when a relatively high value of the charging voltage of the main capacitor is detected. SOLUTION: Voltage of a power source 1 is smoothed by a power source filter 104, and applied to an oscillating circuit 102 provided with an oscillating transformer 13, and high-tension pulse voltage is generated based on the control signal from a charge signal generating circuit 34 and a stroboscopic pulse signal generating circuit 35. This voltage is applied to a trigger circuit 103 through diodes 14, 15 so as to charge a main capacitor 29. A stroboscopic tube 26 is lighted by the charging voltage through a trigger coil 23. At this stage, when a relatively high value of the charging voltage of the main capacitor 29 is detected by a charging voltage detecting circuit 36 connected to the diode 14, a stroboscopic pulse signal generating circuit 35 is controlled through a CPU 101 so as to widen the pulse width or shorten the pulse cycle.

Title: Liquid crystal orienting film
Inventor: YANO EI
IPC: G02F1/1337
Filed: 1990-09-18
Abstract: PURPOSE:To obtain stable memory performance simultaneously with the orientation of a ferroelectric liquid crystal without a rubber process by constituting the orienting film with a high molecular Langmuir-Blodgett(LB) film and the thin film of a conductive polymer laminated on the LB film. CONSTITUTION:The liquid crystal orienting film 3 is formed as a function- separated composite structure. Namely, the liquid crystal orienting film 3 accumulates the thin film 5 of the conductive polymer on the high polymer LB film 4 with anisotropy. Then FLC is oriented without rubbing by using the high molecular LB film 4. The LB film is an extremely thin film and when high molecules are used as film molecules, a monomolecular film is extended at the time of the accumulation, so that the LB film 4 has anisotropy depending upon the dipping direction of a substrate. This anisotropy provides the same effect with the rubbing of a high molecular film formed by a rotary coating method and can orient the FLC. In addition, as for the memory performance a conductive polymers are laminated to the thickness small enough not to cancel the anisotropy of the LB film 4 as a base, thereby making the LB film 4 conductive and preventing the charges from accumulation.

Abstract: PURPOSE:To prevent a grindstone from suffering from loading by applying conductive fluid between a grindstone side and a fitting stand side for a workpiece to send an electric current between them, and providing a means to electrify cut dust produced simultaneously with the grinding process, in the same polarity as that of the grindstone to separate and extract cut dust from the grindstone. CONSTITUTION:Conductive fluid 4 is applied between a grindstone 1 and a fitting stand 2 for a workpiece 3 by supplying water or an electrolytic solution as a grinding solution to a surface to be processed. An electric current is sent toward the grindstone fluid 4. In this condition, while the workpiece 3 is ground by the grindstone 1, cut dust 5 produced with this grinding process is electrified by the electric current to the same polarity as that of the grindstone 1, and separated from the stone 1. The isolated cut dust 5 is swept away from the grindstone 1 and the workpiece 3 on the fitting stand 2 by flowing pressure of the conductive fluid 4. As the result, the grindstone 1 can act on the workpiece 3 always as a sharp cutting edge without being coaded.

Abstract: PURPOSE:To make it possible to release users from a setting work of troublesome thawing time and embody natural thawing definitely. CONSTITUTION:When it is thawing operation mode, a magnetron 15 operates for a specified time and then stops the operation for a specified time and leaves a frozen food 14 as it is. On the other hand, a temperature sensor 16 detects each temperature before and after the frozen food is left unattended and presumes temperature variations (temperature distribution) between the inside and the outside of the frozen food 14 based on the differential temperature before and after. When no temperature variation prevails, the thawing operation mode is ended, but when there exist temperature variations, heating time is reset in conformity with the degree. Once again, a similar thawing operation mode is repeated. When the temperature variations are eliminated, the thawing operation mode will come to a halt automatically in this stage.
