Title: Transmitter-receiver
Inventor: TOMINAGA YOSHITADA
IPC: H04R17/00
Filed: 1981-09-01
Abstract: PURPOSE:To make a wave transmitter and a wave receiver into one body to make the structure small-sized, by using a material, which has an acoustic impedance approximating that of a medium, as a plate-shaped piezoelectric material. CONSTITUTION:This wave transmitter-receiver consists of a cylindrical or ball- shaped box body 1 and plate-shaped piezoelectric materials 2-1, 2-2. 2-3, and 2-4 which are fixed onto the circumference of the box body so as to face to each other as one pair at least, and two piezoelectric materials facing to each other are defined as one set, and differences between respective inputs and outputs are synthesized to obtain directivity. When acoustic waves come, the box body 1 is oscillated back and forth in the advance direction. Therefore, the force of compression or expansion acts upon two piezoelectric materials, and voltages having phases opposite to each other are induced in them respectively. The difference between both voltages is synthesized to take out the 2-fold voltage.

IPC: B29K23/00
Filed: 1995-05-09
Abstract: PURPOSE: To obtain an ultrahigh molecular weight polyethylene molded article by injection molding by cutting a gate part which connects a runner part to a product part before pressure molding after the finish of injecting the polyethylene into an injection molding die. CONSTITUTION: In a movable side mold 10, a gate seal part 26 which is installed in a part of part of a runner part forming part 16 and a gate part forming part 24 separately from the mold 10 is made movable so that at least a gate part 22 is separated from a product part 14. When a reversible motor 36 is driven, since a balancing arm 32 is turned at a given angle, its movement is transmitted to the gate seal part 26 to turn the gate seal part 26. Accordingly, after the finish of injection, by actuating the balancing arm 32 before pressure molding, the gate part is cut from the product part 14, so that pressure by a pressure block 10 is applied only to the product part 14.

Title: Reluctance synchronous motor rotated at half speed
Inventor: YAMADA HIROSHI
IPC: H02K19/06
Filed: 1982-08-06
Abstract: PURPOSE:To improve the efficiency of a synchronous motor by synchronizing at half of the speed of a reference wave revolving magnetic field via a rotor which is formed of a high magnetic permeability only with magnetic irregularity, thereby eliminating a squirrel-cage coil and increasing the magnetic irregularity. CONSTITUTION:A phase advancing condenser 3 is inserted into one of a 2-phase stator coils 2 to flow direct current only to the phase in which the condenser 3 is not inserted, thereby fixing the position of a stationary magnetic field. When a rotor 1 rotates at the angular velocity of omega0/2, the stator alternating current of angular velocity omega0 is amplitude-modulated by the angular frequency of omega0, and a direct current is flowed to the stator coil. A direct currnt is flowed to the stator coil to generate a stationary magnetic field, thereby producing synchronous torque to the stationary magnetic field produced by the rotor 1 which rotates at the half speed and synchronizing at the half speed. In this manner, a squirrel cage coil can be eliminated, and the magnetic irregularity is increased, thereby enhancing the efficiency.

IPC: H01L29/43
Filed: 1984-07-04
Abstract: PURPOSE:To provide an electrode structure which suppresses a noxious eutectic layer growing on an interface between a silicon element surface and a gold-gallium alloy layer, by defining a ratio of a thickness of a silver layer and that of the gold-gallium alloy layer directly coated on the silicon element, above a specified value. CONSTITUTION:Formed over an n<++> type silicon substrate 1 is an n<+> type epitaxial layer 2 over which a protective film 3 is formed. In an exposed section of the n<+> type epitaxial layer 2 where a portion of the protective film 3 is being removed, a p<+> type region 4 and an n<+> type region 5 are formed in the direction of the device thickness to constitute a p-n junction 6. On the surface of the p<+> type region, a gold-gallium alloy layer 7 with a predetermined thickness below 1,500Angstrom  is evaporated, and a silver layer 8 with a thickness of 10,000Angstrom  is formed thereon. In this way, by defining a ratio of a thickness of the silver layer 8 and that of the gold-gallium alloy layer 7 above 6.6, when the silicon element is heated to a sealing temperature, Ag-Au-Si ternary eutectic is formed, so that a growth of an eutectic layer to be formed on the interface between the p<+> type region and the gold-gallium alloy layer can be suppressed and thus increase of the leak current can be prevented.

Title: Multilayer circuit board
Inventor: SUENAGA HIROSHI
IPC: H05K3/46
Filed: 1992-05-28
Abstract: PURPOSE:To improve connectability between an inner interconnection layer and an end electrode while a multilayer circuit board having the end electrode is reduced in size. CONSTITUTION:A multilayer circuit board 1 is chiefly made up of: a board body 2 composed of integrated sheets 2a... 2h that are obtained by laminating a number of ceramic green sheets and calcining the sheets in an integrated fashion; an end electrode 5 formed on the end surface of the board body 2; and inner interconnection layers 3 formed within the board body 2 and connected to the end electrode 5. A tip end 3a of the inner interconnection layer 3 is connected to the end electrode 5, and the tip end 3a is set to be thicker than the other portion of the interconnection layer. This causes a contact area between the end 3a and the end electrode 5 to be increased, and hence it is less likely that a contact failure will occur between the inner interconnection layer 3 and the end electrode 5.

A change in a pressure inside the container 12 due to its destruction is detected by a pressure gage 14. Its detection signal is used as a control signal, and the implement 20 which is connected to the distance-variable device 16 is stopped by a switching circuit.  Then, the movement distance from the start up to the stop of the implement 20 is measured by using, e.g. an indicator, and a volume inside the container 12 is found automatically on the basis of the movement distance which is found in advance and on the basis of the database of a volume value.
