Title: Phase shift circuit
Inventor: ARAI MASANORI
IPC: H03H11/20
Filed: 1987-03-18
Abstract: PURPOSE:To avoid such a case where the phase control characteristics are affected by the position of a variable reactance like a variable diode, etc., by controlling the phase of a reflector due to the variable reactance for the phase shift of an input signal. CONSTITUTION:The signal applied to an input terminal 16 is supplied to the base of a transistor TR11 and the output signal of a collector is applied to the base of a TR12 as well as to a distribution constant line 15 to be reflected by a variable capacity diode 14 of the termination impedance. When the output signals of collectors of both TR12 and 13 are synthesized together, only the reflected wave signalremains and is outputted through an output terminal 17. The phase of the reflected signal can be controlled in response to the capacity C of the diode 14. Thus it is possible to secure the phase control within a desired range despite extension of a connection line when the diode 14 is externally attached.

Title: Upper dead center detector
Inventor: TAMURA TATSUHISA
IPC: G01D5/42
Filed: 1979-05-18
Abstract: PURPOSE: To accurately detect an upper dead center of a piston in an engine of any construction by providing a connecting member which can be connected to a bore communicated with a combustion chamber, and a pressure detecting pipe connected to the connecting member and adapted to detect the pressure in the combustion chamber.  
     CONSTITUTION: A connecting member 7 is screwed to a plug bore 6 formed in a cylinder 2, and a pressure detecting pipe 13 is fitted at its one end portion around a lower end surface 11 of the member 7. When a piston 3 is upwardly moved, the air pressure in a combustion chamber 4 is increased and a surface of a lubricating oil 14 on the distant side with respect to the member 7 raised. When the piston 3 is downwardly moved, the pressure in the combustion chamber 4 is decreased so that the oil level on the side of the member 7 is raised with the oil level on the distant side with respect thereto lowered. Therefore, when the piston 3 exceeds an upper dead center, movement of the surfaces of the lubricating oil 14 are stopped accordingly to be then moved in the opposite direction. Thus, an upper dead center of the piston in an engine of any construction in the levels of the lubricating oil 14 in the detecting pipe 13. Therefore, an upper dead center of a piston in an engine of any construction can be accurately detected with the detecting operation not influenced by the arrangement of a plug 6 and the shape of the upper surface of a piston 3.

Filed: 1999-03-09
Abstract: PROBLEM TO BE SOLVED: To obtain a semiconductor device, suitable for capacitor microphone drive by a method, wherein one end of a parasitic capacity attributable to extended electrode requiring a large area, is set at high resistivity. SOLUTION: In this semiconductor device, there is formed on a semiconductor substrate 21, an epitaxial layer 23 of high resistivity in which the resistivity is 100 to 5,000 Ωcm, and this is junctioned and isolated to form an island region 25.

The NPN transistor forms an N-type collector region 60 through diffusion in the island region 25, to form a collector layer. The spread of a depletion layer is enlarged to reduce the value of a parasitic capacitance C1, and flowing out of a signal out of the extended electrode 43 to a ground potential GND is prevented.

Title: Mos memory circuit
Inventor: WATANABE TAKAYUKI
IPC: G11C11/417
Filed: 1986-03-18
Abstract: PURPOSE:To activate almost simultaneously a word line and column selecting signal at writing and to shorten the write time by permitting a column decoder to generate the column selecting signal with the aid of a control signal. CONSTITUTION:As soon as the word line WL1 is selected, a write data input buffer 6 is also activated by a write control signal thetaWE1, and write information is transmitted to data bus lines DB1 and the inverse of DB1. A column decoder activating signal thetaYjWE and the column selecting signal Yij are made at a high level, because almost simultaneously the write control signal thetaWE1 rises and a the inverse of thetayj has already risen. As soon as the write information is transmitted to the data bus lines DB1 and the inverse of DB1, said information is transmitted to bit lines DG1 and the inverse of DG1. As the activating signal thetaR1 of a sense amplifier remains at a low level due to a write action, the sense amplifier does not work. Since the word line WL1 has been at a high level, the write information is transmitted to a memory cell 1 and is rewritten.

Filed: 1985-03-25
Abstract: PURPOSE:To improve the charging and discharging properties of a nonmaintenance clad lead storage battery, by disposing a plurality of cores in a tube, making the cores of a lead alloy containing substantially no antimony, and connecting the cores to each other at a plurality of points. CONSTITUTION:Cores 1, 1' are made of such a lead alloy containing substantial ly no antimony as a lead-arsenic-silver alloy, a lead-calcium-tin alloy and a lead-antimony-arsenic-tin alloy whose antimony content is 1% or less. The cores 1, 1' are connected to each other by connector 2. Since the cores 1, 1' are surrounded by an active material 4 and firmly held by a tube 3, the active material less softens or comes off and the life of the active material itself is long regardless of the repetition of charging and discharge. Even if the core is partly cut off, the charging and discharge can be performed all right because a plurality of cores are provided in each tube and reticulately connected to each other. The charging and discharting properties of a nonmaintenance clad lead storage battery are thus enhanced.

Abstract: PURPOSE:To minimize the amount of implantation of O<+> ions as well as to prolong the lifetime of the filaments in an ion source by a method wherein an insulating layer is formed in a multilayer structure consisting of an Si oxide layer formed by implanting ions and another insulating layer just under the Si oxide layer. CONSTITUTION:An N<+> layer 30 is formed by implanting deeply N<+> ions in the surface of a silicon (Si) substrate 40. An O<+> layer 20 is formed by implanting O<+> ions shallow than the layer 30, yet in such a way as to overlap partially. As an Si layer 11 on the surface is subjected to damage after it has experienced an ion-implantation process, the Si layer 11 is annealed for 3hr in an atmosphere of 1,200 deg.C and N2 and returned to a 100 single crystal Si layer 10. At this time, both nitriding and oxidation are performed and the layer 20 and the layer 30 are each turned into an SiO2 layer and an Si3N4 layer.
