Title: Shift register
Inventor: YOSHIDA SHINICHI
IPC: G11C19/00
Filed: 1982-11-19
Abstract: PURPOSE:To ensure a high-speed resetting action without increasing the number of an element by providing a resetting circuit which sets forcibly a mutli-phase clock signal at a level for connection of all stages by a resetting signal and at the same time supplies the resetting signal through an input terminal. CONSTITUTION:A input circuit consist of AND gates G1 and G2, an inverter IV3 and an OR gate G3. An output signal is fed back to the input of the gate G1; while the input data IN is supplied to the input of the gate G2. Then a control signal C is impressed to the other input of the gate G1; while a control signal inverted by the inverter IV3 is impressed to the other input of the gate G2. The gate 1 is opened if the signal C is set at logic ''1'', and the gate G2 is closed. Thus a shift register SR holds the data with its feedback loop. When the signal C is set at logic ''0'', the gates G2 and G1 are opened and closed respectively. Thus the register SR sets the input data.

Title: Discharge lamp device
Inventor: NAMIKOSHI YASUMASA
IPC: H05B41/23
Filed: 1987-08-13
Abstract: PURPOSE:To save power consumption and prevent blinking of a lamp by providing an intermediate tap on a filament and applying discharging DC power supply between the intermediate tap and an anode as well as applying a preheating DC power supply on both ends of the filament. CONSTITUTION:An intermediate tap 2a is provided on a filament 2 and preheating AC power supply 3a is applied to both ends of the filament 2. In addition, a discharging DC power supply 5 is applied between the filament 2 and an anode 4. According to this constitution, even if the polarity of a preheating AC power supply 3a applied to the filament 2 is inverted, the lamp current hardly changes causing no blinking of the lamp. Furthermore, since there is no chance for the lamp current to flow through the secondary winding n2 of a preheating transformer Tb, a power loss is extremely small, thus enabling the power consumption to be saved considerably.

IPC: G06F11/28
Filed: 1986-08-28
Abstract: PURPOSE:To protect the secrecy of data by checking program data in an IC card. CONSTITUTION:When a card is loaded on a tester and a test starting instruction is outputted from the tester, the starting instruction is fetched from an I/O terminal through an input controller 24 and an input buffer 23 into an IC card.

Title: Rice boiler
Inventor: SUZUKI TOSHIAKI
IPC: A47J27/00
Filed: 1990-07-30
Abstract: PURPOSE:To obtain delicious rice by the synergism of lid heating and an effect of controlling the application of electric current to a heater for boiling rice by switching to the second set temperature higher than the first set temperature when a temperature sensor detects a temperature set higher than the first set temperature. CONSTITUTION:When it enters a boil-up process, electric current is fully applied to a rice boiling heater 2 by a current application control means 7. When the water temperature rises in a short time and the steam starts to be generated, the steam is applied to a lid 4, and the lid 4 is heated by the steam this time. A temperature sensor 6 provided on the lid 4 detects such a temperature rise, it is judged to be boiled when the sensor detects a temperature T (about 70 deg.C). When boiling is judged, the heating amount for the rice boiling heater 2 is decreased by the current application control means 7. Simultaneously, the set temperature of a temperature control means 8 is switched to the second set temperature (about 120 deg.C), so that the temperature of the lid 4 is controlled to the second set temperature from now and after. As the steam is generated before the interior of an inner pot 3 is completely boiled and the temperature T is set to a comparatively low temperature, about 70 deg.C, boiling can be detected a little before the interior is actually boiled and steam is generated hard.

Abstract: PURPOSE:To obtain an X-ray mask in a high contrast by a method wherein an absorber pattern is formed directly onto the surface of a substrate, a transmission film is shaped so as to bury one part of the pattern and the substrate in a required section is removed and used as the X-ray mask. CONSTITUTION:When a BN (boron nitride) film 7 is formed onto the surface of a substrate 5, to which a gold pattern 6 is shaped completely, through plasma CVD (a lightning chemical vapor growth method), the BN film 7 is formed to a shape that the surface of the gold pattern 6 is also coated simultaneously. An OFPR800 resist is applied onto the surface of the BN film 7, an OFPR800 film 8 is formed through heating, and the OFPR800 film 8 is removed through etching and the flat BN film 7, from which the nose of the gold pattern 6 is projected, is acquired. A polyimide film 9 is shaped onto the surface of the BN film 7, and the central section of the substrate 5 is gotten rid of, thus obtaining an X-ray mask. Accordingly, the thickness of an absorber pattern absorbing X-rays is thickened, and a protective film as the upper layer of the pattern can be thinned, thus acquiring the X-ray mask in a high contrast.
