Abstract: PURPOSE:To park vehicles in upper and lower two stages, with a simple composition by digging a inclined pit underground, leaving an open space of more than the height of a vehicle above the pit and slantly moving a pallet freely around the rear end portion of the pallet where it is supported. CONSTITUTION:Triangular shaped pallet supporting frames 3 are provided, opposed to each other, on a ground surface 2 on the right and left side at the center portion of an inclined pit 1 in its longitudinal direction so as to support a slantly movable pallet 4 on an upper portion 3a.

Patent JP-S63205532-A (JP)
Title: Pressure sensor
Inventor: UEDA SHINICHI
IPC: G01D5/22
Filed: 1987-02-20
Abstract: PURPOSE:To obtain a small-sized pressure sensor by detecting unbalanced voltages of two secondary coils which are generated by the displacement of sensor metal with pressure. CONSTITUTION:When a high-frequency voltage is applied to the primary coil 10 of a differential transformer, the two secondary coils 11 and 12 induce equal voltages, but the sensor metal 7 is not at the center part between the coils 11 and 12, so unbalanced high-frequency voltages are induced under the influence of an eddy current induced in the metal 7. Then the socket 1 of the differential transformer is connected to a pressure medium and the pressure of the medium is raised, the diaphragm 4 is pressed and displaced. The two coils 11 and 12, therefore, vary in impedance to generate unbalanced voltages corresponding to the displacement position of the metal 7. Those are rectified respectively to detect their difference voltage, and then the pressure is detected. Thus, the high-frequency voltage is applied to the primary coil, so the coil is reduced in size and the pressure sensor is reduced in size.

Title: Manufacture of semiconductor element
Inventor: SANO YOSHIAKI
IPC: H01L29/808
Filed: 1978-04-05
Abstract: PURPOSE: To increase the degree of integration for FET as well as to ensure the high-frequency operation by omitting the mask matching and also forming the electrode through the self-matching.  
     CONSTITUTION: Poly Si23 is tiered up on n- and p-layer, and layer 23 is etched via Si 3 N 4  mask 24. Then the CVD method is applied to laminate SiO 2 25, poly Si26, SiO 2 27 and Si 3 N 4 28 each, and the ion is injected on the entire surface to accelerate the etching speed selectively. Films 28W25 are etched continuously with the window drilled, and p +  diffusion layer 29 and SiO 2 30 are formed with film 27 and 30 used as the masks. Then film 24 and 28 are removed, and the phosphorus is diffused through film 23 and with film 27 and 30 used as the masks to form n +  layer 31. Parts 27, 30 and 32 of remaining film 25 on the substrate surface are removed, and layer 29 and 23 are exposed again to deposit electrode 33 and 34. In this method, the space between layer 31 and 29 is determined only by etching of layer 23, thus increaseing the degree of integration for the element. At the same time, the ballast resistance value can be controlled via the ion injection only to layer 23 without mask matching, and thus both the parasitic capacity and the base resistance can be reduced to ensure the high-frequency operation.

Filed: 1984-03-01
Abstract: PURPOSE:To attain the reduction of power consumption depending on the processed amount by discriminating the quantity of processing to be operated for the circuit and changing the common processing clock frequency accordingly. CONSTITUTION:Every time a content to be processed by a program is lost in a circuit comprising a CPU1 of CMOS type, an oscillator 2 oscillating a clock at a frequency of plural steps, a counter 3 controlling the frequency and a clock oscillator 4 of a prescribed frequency, a pulse counting down the counter 3 is outputted. The counter 3 is counted up by the clock oscillator 4 in addition to the count-down control from the CPU1. The counter 3 is controlled so as to increase the processing clock frequency of the oscillator 2 as the counter value is higher. Thus, when the CPU1 has much pocessing amount, the output frequency of the count-down pulse is decreased, the processing clock frequency is increased and vice versa.

Filed: 1993-03-01
Abstract: PURPOSE:To avoid erroneous judgement due to variation of the rotational speed of an engine by respectively detecting the rotational speed of the engine before and after the opening and closing of an EGR valve and stopping the judgement of a failure when a difference between the rotational speeds exceeds a predetermined range. CONSTITUTION:An EGR valve 9 provided in a path 8 affording communication between an exhaust path 7 and intake path 2 of an engine 1 is temporarily opened and closed in the deceleration region of the engine 1. Whether or not the differential pressure of intake pressure before and after the valve 9 is opened and closed falls within a prescribed range is judged to decide the exhaust gas recirculating device(EGR) has a failure. The rotational speed of the engine 1 is detected respectively before and after the EGR valve 9 is opened and closed and when the rotational speed exceeds a prescribed range, the judgement of the failure is stopped. Thus, the failure of the EGR can correctively judged.
