Title: Intermittent operating circuit
Inventor: TANIGUCHI MASAYOSHI
IPC: G06F1/04
Filed: 1985-02-01
Abstract: PURPOSE:To reduce the power consumption of the whole circuit by providing an oscillator for a basic clock signal as a clock signal source and an oscillator which generates a clock signal of frequency lower than that of the basic clock signal, and using the basic clock signal in functional operation and the other clock when the operation is not performed. CONSTITUTION:For example, a latch circuit 9s set and the latch output Q is at a high level. In this case, the high-level latch output drives a clock signal oscillator 2 and a timer circuit 7 selectively. the Q output of the latch circuit 8, on the other hand, is inverted by inverters 9 and 10 to a low level and inputted to a basic clock signal oscillator 1 and a temperature measuring circuit 6, so those circuits do not operate. When the timer circuit 7 clocks a specific time to enter a time-up state, the driven clock signal oscillator 2 and timer circuit 7 stop operating and a high signal is inputted to the basic clock signal oscillator 1 and temperature measuring circuit 6 through the inverters 9 and 10, so that those circuits start operating.

Title: Olefin manufacture
Inventor: KAARUUERUNSUTO HOFUSHIYUTATSUT
IPC: B01J23/76
Filed: 1981-02-13
Abstract: A process for the production of olefins from synthesis gas comprises a first synthesis stage in which a mixture of methanol and higher alcohols are formed from a synthesis gas comprising hydrogen and carbon monoxide. The catalyst for the first synthesis stage comprises the oxides of copper and zinc in intimate association with each other and a promoting compound selected from the group consisting of chromium, cerium, lanthanum, manganese, thorium, and an alkali metal. The materials from the first synthesis stage are separated into a gas phase and a liquid phase. Thereafter the methanol is separated from the higher alcohol fractions. The higher alcohols are then subjected to dehydration in a dehydration stage which comprises passing the higher alcohol fraction over an alkalized dehydration catalyst at a pressure in the range of 0.5-1 bar and a temperature in the range of 350 DEG -500 DEG  C. Thereafter the olefins produced by the dehydration of the higher alcohols are separated into the olefinic and non-olefinic materials. Preferred dehydration catalysts include alkalized aluminum oxide and alkalized calcium phosphate.

Title: Method for measuring shaft weight of traveling vehicle
Inventor: SENCHI HIROYUKI
IPC: G01G19/03
Filed: 1987-01-31
Abstract: PURPOSE:To remove the influence of vehicle vibrations as much as possible and to obtain a shaft weight value close to a true value by quantizing the analog output signal of a shaft weight detection part as a time-series data signal and finding the shaft weight value from the quantized data sequence. CONSTITUTION:The analog output signal of the shaft weight detection part is quantized as the time-series data signal and the shaft weight value is found from this data sequence. Then the wavelength of vehicle vibrations corresponding to a traveling speed is estimated from the quantized number of the data sequence obtained from right after the tires of a vehicle to be measured begins to move onto a shaft weight detection part to right before the vehicle gets off. When the vibrations are within an area of wavelength wherein the waveform of the vibrations are considered to be a sine wave, two points corresponding to specific length in nearly one period of wavelength are set at the intermediate part of the data sequence arrayed in a time-base direction and the variation configuration of respective data values of the data sequence between the two points with time are classified by upward projecting, downward projecting, right rising, and right falling; and those four variation configurations are made to correspond to parts closest to the sine wave and correcting arithmetic for finding a data value corresponding to the intersection of the sine wave and the time base as the shaft weight value is carried out.

Filed: 1980-02-20
Abstract: PURPOSE:To prevent layers from increasing in number as well as the mixture of currents flowing in and out by a method wherein the opposed electrode is elongated, and the signal current is made to flow in from said elongated portion. CONSTITUTION:One end of the opposed electrode 14 is elongated along the base- portion electrode 12, and said elongated portion is used as a signal line 22. The other end of the electrode 14 is connected to the ground plane 10 to ground. In said element, when a signal current IH is passed from the signal line 22, an image current flows through the electrode 12 and the plane 10 as shown by arrows, and the magnetic field acting upon the tunnel junction 16 is determined by the signal current IH and its image current i3. Besides, the signal current, which flows along the course, 22-14-10, never passes through the output end unlike the bias current. In addition, in said element, because the signal current directly applies a magnetic field to the tunnel junction, the magnetic field has the value obtained when the thickness of the insulating layer 20 is zero, so that a large magnetic field value can be obtained.
