Title: Image rotation system
Inventor: ISHIKAWA YASUNORI
IPC: G06T3/60
Filed: 1985-03-04
Abstract: PURPOSE:To perform fast image rotation processing without complicated calculation nor processing by rotating image data by 45 deg. through coordinate conversion and interpolating parts free from picture element with nearby picture elements, and thus generating a 45 deg.-rotated image. CONSTITUTION:When coordinates of 16 picture elements A11-A44 are denoted as (i0, j0), coordinates after 45 deg. rotation are (i0-j0, i0+j0). Then, values at lattice points which have the same X coordinates while Y coordinates are one less are employed for lattice points (marked with 'x') where no picture element is present to perform interpolation. Then, the image is reduced because the area is double.

Title: Treatment of carbon monooxide-containing waste gas
Inventor: INABA SHIGEYA
IPC: B01J23/89
Filed: 1978-04-11
Abstract: PURPOSE: Ring or other type steel material is Al-plated, Al is then diffused into the steel material, and treated by Al soluble solution to make its surface porous, Next, the material is heat treated, followed by Pt carrying treatment at specific condition, providing an effective material for complete CO oxidation at low temperature under low loss of pressure.  
     CONSTITUTION: Ring, honeycomb, or plate type steel material is Al-plated and  heat treated at a preferable temperature of 800°C for about one hour so that Al  is diffused into the steel material. Then, aqueous NaOH solution or the like is used  to dissolve out Al to render the material surface porous, and treated for oxidation at room temperature to 400°C in O 2  atomosphere. The resulted material is immersed into aqueous H 2 PtCl 6  solution with pH controlled to 8 - 10 by Ba(OH) 2  so that Pt is carried by the material. The material is dried and used as catalyst to be contacted with CO-containing waste gas. The catalyst exhibits stable activity, without being poisoned by SO 2  and shows little activity for SO 3  oxidation.

Title: Controller for automatic constant speed traveling device of car
Inventor: KIMURA SHIGEHIRO
IPC: B60K31/00
Filed: 1982-03-18
Abstract: PURPOSE:To ensure the automatic traveling of a car at a constant speed, by resetting the speed to a level set before a clutch is operated without performing the setting again even after the clutch is operated by means of a comparison deciding device for the gear shift position, a storage circuit, a comparison operator and an output control circuit. CONSTITUTION:A clutch switch (C) is broken to have a gear shift while a car is automatically traveling at a constant speed. Thus a signal is fed to a comparison deciding device 3 via a switch input control circuit 5 to store the speed of the car set right before a clutch is switched and a ratio between the rotational frequency of engine and the speed of car into a storage circuit 6. At the same time, the valve of an actuator 9 is switched to release the automatic traveling of a constant speed. Then the switch (C) is made again, the device 3 detects the ratio between the rotational frequency of engine and the speed of car of that time point and compares this ratio with that obtained right before the clutch is broken through a comparison operator 7. Then the valve is switched to a state set right before the clutch is switched in case the gear shift is shifted up.

Title: Preventing device for tilting of ram of press brake
Inventor: SENDA HIROAKI
IPC: B21D5/02
Filed: 1981-03-26
Abstract: PURPOSE:To prevent tilting of the ram of a press brake perfectly by controlling supply of pressure liquid of a hydraulic device basing on detection of tilting of the ram. CONSTITUTION:When a platy ram 15 provided with a punch, an upper die, is tilted while going down, a rack 28 of one side goes down faster than that of the other side. In this case, as a support 30 is allowed to rotate freely around a pin 25, a shaft 31 tilts to the same direction and by the same angle with the ram 15. That is, the shaft 31 acts as a member for detecting tilting of the ram 15. Displacement caused by tilting of the shaft 31 is magnified three times by a bell crank 44 and transmitted to a movable member 40 to move the member 40. Consequently, one of clearance 52 between an inflow port 37 and an outflow port 38 becomes narrow and flow of oil to the cylinder of one of hydraulic device 16 is reduced. Thus, tilting of the ram 15 is eliminated immediately.

Title: Heating device for vehicle

IPC: F24J3/00
Filed: 1997-02-27
Abstract: PROBLEM TO BE SOLVED: To conduct the heat to the cooling water for heating by providing a branch pipeline for bypassing a hydraulic pump to a hydraulic circuit for circulation of the operating oil in the condition that a main pipeline is cut, a throttle means for giving the hydraulic resistance to the operating oil so as to generate the heat, and a heat conducting means for blowing the generated operating oil heat into a cabin. SOLUTION: When an ECU 38 judges that the cooling water temperature is less than the predetermined value at the time of starting the cooling, in the case where a heater valve 27 is not opened, the heater valve 27 is operated for opening, and a heater valve 33 is operated so as to flow the operating oil from a hydraulic pump 12 to a branch pipeline 35.  Since the cross section of the passing operating oil is narrowed by the throttle 36 and the flow speed is increased and the flow per each unit area is increased, friction between the operating oil and the sharing force are generated, and the friction force between the pipe wall is increased, and a radiation part 37 is repeatedly heated by the operating oil heat so that the temperature is quickly raised in a short time in comparison with the heating using the cooling water, of which temperature is raised by the combustion heat of an engine 11. The warmed cooling water heats a heater core 18, and warms an air flow of a blowing fan 30 so as to perform the heating of a cabin.
