Title: Heating system for preheating plug of diesel engine
Inventor: YASUHARA SHIGEFUMI
IPC: F02P19/02
Filed: 1978-09-18
Abstract: PURPOSE: To reduce the cost of a heating system for a preheating plug and raise the durability of the system, by utilizing a hydraulic switch of an engine to control the energization of the preheating plug to cause effective after-glow.  
     CONSTITUTION: The hydraulic switch 5 is opened when the oil pressure of the engine reaches a prescribed level. When a glow switch 1 is pressed prior to the starting of the engine, the hydraulic switch 5 remains closed and the coil 3c of a two-contact relay 3 is energized by a battery 2. As a result, contacts 3a, 3b are closed, the preheating plug 4 is energized and the relay 3 is self-sustained. When the oil pressure of the started engine reaches the prescribed level, the hydraulic switch 5 is opened and the preheating plug 4 is deenergized. This results in reducing the cost of the heating system for the preheating plug and raising the durability of the system.

Title: Thermal transfer copying method
Inventor: TAGIWA IZUMI
IPC: B41J2/325
Filed: 1986-05-20
Abstract: PURPOSE:To enable a double-side original, a book or the like to be easily copied, by providing a step of obtaining an ink image on an intermediate transfer body as a mirror image of an original, and a step of laying a transfer body on the ink image side of the intermediate transfer body and heating to transfer the ink image onto the transfer body. CONSTITUTION:Rays alpha from a light source 11 are transmitted through the intermediate transfer body to reach an original 16. At a ground part of the original, a part of the rays is scattered as indicated at delta', while other part is transmitted as indicated at delta, so that neither of the parts of the rays generates heat. On the other hand, at an image part 16a, the rays alpha are absorbed to generate heat. The heat beta thus generated is transmitted to an ink layer 14 to melt the ink at the part facing the image part 16a. The melted ink 17 forms a mirror image of the image part 16a. The intermediate transfer body 12 with the ink image 12a (mirror image) formed thereon is released from an ink sheet 15, and is passed between a heated roller 19 and a pressing roller 20 together with a sheet 18 laid thereon, whereby the ink is thermally melted and is transferred onto the transfer body 18, thereby obtaining a copy image corresponding to the image of the original.

Title: Analog multiplier for neuro circuit
Inventor: NAKAMURA JOJI
IPC: G06F15/18
Filed: 1992-05-06
Abstract: PURPOSE:To provide a drain current output corresponding to an arbitrary drain voltage even in the saturated area of an FET by respectively inserting and connecting resistors between the drain electrode of the FET and a bulk and between the bulk and the source electrode. CONSTITUTION:A resistor 12 is connected between the drain electrode of an MOSFET 11 and the bulk, and a resistor 13 is connected between the bulk and the source electrode. The source electrode is grounded, and a drain current Id in proportion to the product of a gate voltage Vg and a drain voltage Vd flows to this ground circuit. When the drain voltage Vd is increased, a bulk potential is increased, and a drain current Id is increased. Therefore, the drain current Id corresponding to the change of the gate voltage Vg or the drain voltage Vd is secured even in the state of setting the gate voltage Vg to the saturated area where it is lower than the drain voltage Vd. Thus, the learning arithmetic of a neural network is surely executed.

The mask 4 is used again to perform anisotropic etching and to form grooves 7 regulated in their sizes by the mask 4 in the p-type regions 6 doped deep at low concentra tion. Further p-type regions 8 are formed to remain more widely than the regions defined by the mask. Hence the regions doped deep at low concentration can be formed more widely than at the regions regulated by the mask.
