Title: Valve timing adjusting device for internal combustion engine
Inventor: ADACHI MICHIO
IPC: F01L1/344
Filed: 1995-10-20
Abstract: PROBLEM TO BE SOLVED: To execute high accurate phase control by reducing pressure oil leakage from an oil pressure chamber by a simple structure. SOLUTION: A seal thin plate 50 is interposed between a vane rotor 9 and a gear 1. The seal thin plate 50 is a thin plate formed in a doughnut shape, and the annular inner circumferential projected part 51 of the seal thin plate 50 and a projected groove 52 outwardly extended in a three-radial direction at intervals at approximately equal angles from the inner circumferential projected part 51, are brought in contact with the vane rotor 9 by elastic force. The inner circumferential projected part 51 is brought in contact with the whole periphery of a supporting member 9d, so that pressure oil in each oil pressure chamber is prevented from being leaked inside in the radial direction.  The projected groove 52 is attached to be always brought in contact with the end surfaces of vanes in an angle range between a maximum phase lag position and a maximum phase advance position even though three vanes arranged around the periphery of the supporting member 9d are rotated, so that the leakage of the pressure oil in a peripheral direction can be reduced. Therefore, oil pressure in each oil pressure chamber can be set at a predetermined value so that high accurate phase control can be executed.

IPC: G06K19/07
Filed: 1992-08-24
Abstract: PURPOSE:To prevent the destruction of data due to the defective contact and the fluctuation of the supplied voltage for a card-shaped semiconductor memory which receives the operating voltage from the outside. CONSTITUTION:In a storage provided with a semiconductor storage circuit 1 and a CPU which are stored in a case and a voltage supply contact P and a data input/output contact T set on the surface of the case, a switching means 6 for a node P and a CPU operating voltage supply terminal, a voltage normalcy deciding means 5 are included. The voltage is checked between the contacts P and E, and the means 6 is turned on when the checked voltage is normal. Thus the operating voltage is supplied to the CPU for transfer of data. If both contacts P and E have the electrical contact defects due to the contamination, etc., or the supplied voltage has the fluctuation, the value of voltage supplied to the means 5 becomes abnormal, the means 6 is kept in an OFF state and then in a pause state even after the CPU is loaded. Thus it is possible to prevent an accident due to the runaway of the CPU caused by the incomplete voltage.

Title: Manufacture and usage of semiconductor integrated circuit and protecting device and doping mask
Inventor: GOSSNER HARALD
IPC: H01L21/266
Filed: 1998-09-28
Abstract: PROBLEM TO BE SOLVED: To accurately set operating voltage without changing manufacturing process steps of a semiconductor integrated circuit by putting a second area into a semiconductor substrate, connecting it to a first area and connecting it to a potential line or a terminal pad. SOLUTION: When abnormal signals enter through a terminal pad 3 and they exceed threshold of a vertical protecting diode 14', a space charge layer at a pn junction 13 between a diffusion area 9 as second area and a buried layer 8 as first area is broken down and the protecting diode 14' is brought into conduction. In this way, a current passage from the terminal pad 3 up to a first potential line 5 through a connection area 22, the buried layer 8 and the diffusion layer 9 is formed. The abnormal signals are accordingly guided to the first potential line 5 and thus do not reach a semiconductor integrated circuit 1. In this case, since the whole diffusion area 9 is uniformly doped, the operating voltage of the protecting diode 14' can be accurately set.

IPC: G03B7/26
Filed: 1986-11-19
Abstract: PURPOSE:To surely recognize cap set state with a simple mechanism to prevent blind exposure by generating an electric signal different between setting and non-setting of a lens cap by a sensor and cutting off the power of a partial circuit if the signal for wetting is generated. CONSTITUTION:If a lens cap 30 is set, a rib 32 intercepts transmission/reception light of a photointerrupter to generate the electric signal. This electric signal is sent from a lead wire 41 to the circuit in a camera body through a contact plate 42 and a connection terminal 43. When a power switch 45 is turned on, the signal from the connection terminal 43 acts upon a relay 48, but a current flows to a recording circuit 47 from a battery 46 if the lens cap 30 is not set. When the power switch 45 is turned off or the lens cap 30 is set, the current does not flow to the recording circuit 47 to inhibit recording and a lamp 'REC PAUSE' in a finder is not lit to inform a user that recording is impossible.

Abstract: PURPOSE:To enable an electronic component suction head to hold a larger electronic component by suction without increasing the suction head itself in size by a method wherein the tip of one of suction nozzles is provided protruding farther than the tips of the other suction nozzles. CONSTITUTION:While a protruding mechanism is kept out of operation a first suction nozzle 6a out of a first to a fourth suction nozzle, 6a-9a, is set the largest of all the other suction nozzles in protrusion quantity from the lower end face of a housing 4, and a second suction nozzle 7a, a third suction nozzle 8a, and a fourth suction nozzle 9a are so controlled in length as to decrease gradually in protrusion quantity in this sequence. When the protruding mechanism is set into operation, the first to the fourth suction nozzle, 6a-9a, are controlled in drive stroke so as to make a distance (h) between the lower end face of the housing 4 and the mounting 13 of an electronic component 11 equal.
