Title: Automatic voltage switching device
Inventor: NISHIKAWA HIROSHI
IPC: H02M7/06
Filed: 1983-01-19
Abstract: PURPOSE:To enable to remove artificial load in the matching of a rated voltage between a machine and a power source and to readily supply electric power even to a heavy load by providing a plurality of rated different primary side input circuits in transforming means. CONSTITUTION:When the AC input of a rated voltage 115V is applied from a power source plug PC to the winding L1 of a rated input 115V, a rated DC voltage V2 is applied to a voltage detector which has Zener diode Z and resistors R1, R2 of a control circuit 7 through a winding L3 and a rectifying and smoothing circuit at the secondary side of a transformer PTR. Since the voltage V2 is lower than the Zener voltage, transistors T1, T2 become OFF, and a relay coil M does not operate. Then, when an AC input of rated 230V is applied from the plug PC in this state, the AC voltage of approximately double of the rated output value is inducted at the secondary side of the transformer PT, a drive current is flowed to a relay coil M due to the conduction of the Zener diode Z and the transistors T1, T2 by the rectified voltage, thereby switching the contact of an input selector S to NO side.

Title: Ink jet recording head and its manufacture
Inventor: MASUDA KAZUAKI
IPC: B41J2/05
Filed: 1989-01-13
Abstract: PURPOSE:To form the taped shape of an orifice so as to narrow its jet-out side and to sufficiently and stably obtain a necessary amount of ink drops for recording and a jet-out speed by forming the orifice in such a way that excimer laser beams are projected on a root and an orifice forming member from the recessed part forming an ink channel after they are integrally formed. CONSTITUTION:In a die, the ink jet recording head is.molded without possessing the orifice 11. A laser device irradiates excimer laser beams 2 at a position where the orifice is formed from the ink channel side of an orifice plate 10, and the resin is removed and evaporated to form the orifice 11. The excimer laser beams 2 are projected on the plate 10 from the ink channel side 14 via a mask 4. The excimer laser beams 2 are converged by tilting one side theta1=2 deg. with respect to an optical axis 13, and are projected in the direction perpendicular to the orifice plate 10 by tilting the optical axis 13 by theta2=10 deg.. Thus, the laser beams are projected from the ink channel side, whereby the cross-sectional area of the orifice of a tapered shape shrinks in the jet-out direction.

Title: Temperature coefficient organic positive characteristics thermistor
Inventor: SAKAI HIROSHI
IPC: H01C7/02
Filed: 1992-01-20
Abstract: PURPOSE:To provide an organic positive temperature coefficient characteristic thermistor which has a steep rise of the PTC characteristics and shows a large resistance change and, further, has little variation of a resistance value. CONSTITUTION:The organic positive temperature coefficient characteristics thermistor of the present invention is made of the mixture of thermosetting resin and conductive particles having spike-type protrusions and conductive short fibers. As the mixture of the conductive particles having spike-type protrusions facilitates the flow of a tunnel current because of the shapes of the particles and has better conducting properties than the mixture of purely spherical conductive particles, an initial resistance value at a room temperature can be lowered. As the distance between the conductive particles is larger than the distance between spherical conductive particles, the rise of the PTC characteristics is steep and a large resistance change is provided. The variation of the resistance is smaller than that of the mixture of fiber-type conductive particles. By employing both the conductive particles and the conductive short fibers, the conductive short fibers function as bypasses between the conductive particles, so that the total quantity of added conductive material can be reduced.

Abstract: PURPOSE:To increase a data processing speed by extracting previously the desired data out of those data on plural items via a terminal equipment together with the processing applied to the extracted data and collecting the data processed by a master device via each terminal equipment for output of these processed data. CONSTITUTION:Plural terminal equipments 1 which extract the desired one of data on plural items and apply the processing to the extracted data, a master device 2 which collects the data processed by each equipment 1 and outputs these processed data are provided. Each equipment 1 extracts previously the desired data to be outputted via the device 2 out of those data on plural items. Thus the quantity of processed data is reduced for output. Then the device 2 collects the data processed by each equipment 1 and outputs these processed data. In such configuration, the data are previously and dispersedly extracted and processed by each equipment 1. Thus the least necessary quantity of data is transferred to the device 2 from each equipment 1. As a result, the data processing speed is increased.

IPC: G02B6/44
Filed: 1978-01-26
Abstract: PURPOSE: To facilitate the operation of laying cable by filling the tube with a concentrated solution containing one of the main substances dissolved in sea water or a mixture of such substance and having a specific gravity higher than that of sea water.  
     CONSTITUTION: The operation of laying a cable within a tube is carried out by filling the tube with a concentrated solution containing one of the main substances dissolved in sea water, for instance sodium chloride, potassium chloride and magnesium chloride, or a mixture of such substances. In this way, it is possible to reduce the apparent weight of the cable to an extent corresponding to the buoyancy of the cable. In addition, since the liquid contains the main substance dissolved in sea water, even if it leaks out of the tube, it does not lead to environmental polution.

Abstract: PURPOSE:To execute an interruption of an optional shared device to an optional processor, by providing an interruption number table for recognizing the interruption of the shared device and discriminating the processor to be interrupted. CONSTITUTION:In case when an interruption has been generated from shared devices 4a, 4b, a bus controller 2' detects what has caused its interruption, by the same method of a processor, and senses its interruption number. After the interruption number has been recognized, an interruption number table 7 is referred to in order to discriminate to which processor an interruption request is executed. In the interruption table 7, the number of the processor to be interrupted is stored in accordance with the interruption number which has just been sensed, therefore, the processor number concerned is read out, and the interruption is executed to the processor concerned from the bus controller 2'. Accordingly, each processor 11-1n is capable of receiving an interruption from an  optional shared device.
