Inventor: ARIMA RYOSHI
IPC: B22D41/46
Filed: 1989-01-30
Abstract: PURPOSE:To prevent contamination at the time of discharging molten metal by setting a cylindrical block made of metal, etc., at lower part of a discharging nozzle, packing fine powdery oxide, etc., into gap between the inside of the discharging nozzle and the cylindrical block and coating the upper face with nitride etc. CONSTITUTION:A sliding plate 5 is closed and the refractory-made or metal- made cylindrical block 1 is inserted in the nozzle 4. In the case the gap between the inside of the nozzle 4 and the outside of the cylindrical block is large, plugging material 2 of the fine powder of high m.p. oxide containing the fine powdery nitride or surfactant is packed. Successively, on the cylindrical block 1 and the fine powdery plugging material 2, the pasty high m.p. oxide 3 containing pasty nitride or surfactant is applied. Molten metal 6 is received in a ladle, and by slidingly moving the sliding plate 5 to open, the molten metal can be discharged. By this method, the molten can be easily discharged with remote control without contamination to the molten metal and without any man power.

Inventor: GOTO TSUKASA
IPC: F02P9/00
Filed: 1985-02-04
Abstract: PURPOSE:To suppress the electric-discharge voltage of a spark plug to a low value by connecting a constant voltage element having a set voltage within the distribution of the electric discharge voltage of a spark plug in parallel to the spark plug. CONSTITUTION:A common spark plug 1 is installed into an internal-combustion engine. A constant-voltage element 2 has a set voltage within the range of distribution of the electric discharge voltage of the spark plug 1, and is connected in parallel with the spark plug. A power transistor 5 turns-ON/OFF the electric current on the primary side of an ignition coil 4 according to the ON/OFF-signal supplied from an ignitor 3. The voltage applied into the spark plug 1 is suppressed to a set value within the distribution of the electric discharge voltage by the constant voltage element 2. Therefore, the electric discharge voltage of the spark plug can be suppressed to a low value.

IPC: G08G1/16
Filed: 1995-01-14
Abstract: PURPOSE:To precisely detect a mark even when an optical face has been contaminated and to prevent a malfunction when a traffic lane is detected by a method wherein beams of reflected light from different light receiving regions on the surface of an object are received separately by at least three photodetectors and the mark or the like on the surface of the object is detected. CONSTITUTION:Light projecting elements 10 to 12 are turned on. Respective beams of reflected light are received by photodetectors 14 to 16, they are amplified 21 to 23, and they are then demodulated 24 to 26. Then, a DC signal from the demodulation circuit 24 and a threshold value which is set by a threshold-value generation circuit 13 are compared 29. When the DC signal is larger than the threshold value, 0 is output, and, when the DC signal is smaller, 1 is output. A DC signal from the circuit 26 and the threshold value are compared 30. When the DC signal is larger than the threshold value, 0 is output, and, when the DC signal is smaller, 1 is output. When outputs of the comparators 29, 30 are both 1, the output of an AND gate 31 is 1, and a CPU 32 operates an R alarm 33 so as to inform that a vehicle has come too much to the right side. On the other hand, an optical detection device 110 operates an L alarm 34. In this manner, only when a white line comes in the field of view of the photodetector 15 in the center, the white line is detected, an inessential region is eliminated, and a malfunction is prevented.

Title: Scanning probe microscope
Inventor: HONMA AKIHIKO
IPC: G01N37/00
Filed: 1997-02-04
Abstract: PROBLEM TO BE SOLVED: To display an image without any interruption and flickering by transferring image data from a data memory to an image memory within the fly- back period of a probe-scanning signal. SOLUTION: When a probe 10a performs raster scanning on a sample surface in synchronization with horizontal and vertical scanning signals Sh and Sv for probe, an image signal S in response to the surface shape of the sample is outputted in synchronization with a scanning timing. The image signal S is converted to image data D by an A/D converter 31 within the scanning period of the horizontal scanning signal Sh for scanning probe and is stored at a data memory 32a of a CPU 32 temporarily. The CPU 32 starts an interruption processing at the generation timing of a blank timing signal SB and transmits image data being stored temporarily at the data memory 32a onto a data bus DB2 especially during the blank period of the fly-back period. Data transfer utilizes the fly-back period and also matches a blank period, thus preventing flickering and missing display on a display screen.
