Abstract: PURPOSE:To control the formation of a porous nitride layer and to obtain a stabilized-performance nitrided steel part by heating the part in vacuum or in a nitrogen atmosphere and then heating the part under reduced pressure in the atmosphere contg. NH3, CO2 and N2. CONSTITUTION:Gaseous N2 is introduced into a nitriding chamber, and a steel part is convection-heated to the nitriding temp. in an N2 atmosphere. Gaseous NH3, CO2 and N2 are then continuously introduced in a specified ratio in addition to the supply of N2. The chamber is adjusted to 500-600Torr. The gaseous mixture is subjected to a reaction in the chamber, and the surface of a work is simultaneously nitrided and carburized. Since soft nitriding is carried out under reduced pressure, the oxygen partial pressure in the chamber is lowered, an oxidation reaction is controlled, and the formation of a porous part is repressed. After nitriding is finished, the chamber is evacuated, and the work is introduced into a charging and cooling chamber and cooled.

Title: Swash plate-type compressor
Inventor: KAWAKADO JIYUNZOU
IPC: F04B27/08
Filed: 1979-08-07
Abstract: PURPOSE: To prevent the foaming of the lubricating oil at starting the compressor of a car air-conditioner or the like and the liquid compression resulting from it as well as the lowering of the refrigerating capacity of the refrigerating cycle by separating the oil storage chamber from the flow of refrigerant by means of a partition.  
     CONSTITUTION: Since an oil storage chamber 10 is separated from a suction passage chamber 6b and a discharge passage chamber by a covering wall 23 surrounding a swash plate 2, the lubricating oil raised up by the rotation of the swash plate 2 drops in the oil storage chamber 10 again after lubricating each part. Also the lubricating oil having lubricated a shaft seal 19 returns to the oil storage chamber 10 side, since the shaft seal 19 is separated by a partition 8c of a side housing 8. Consequently, no lubricating oil contact with refrigerant, and even when the pressure in a suction chamber 8b or the suction passage chamber 6b largely lowers, the low pressure is never introduced to the oil storage chamber 10 side. Thus, the foaming of the lubricating oil and the liquid compression resulting from it can be completely prevented.

Title: Three-phase motor driving circuit and three-phase motor driving method
Inventor: KENJO HISASHI
IPC: H02P6/14
Filed: 1997-04-02
Abstract: PROBLEM TO BE SOLVED: To provide a three-phase motor driving circuit and a driving method capable of driving a three-phase motor in a wide rotational region by simple constitution. SOLUTION: When a brushless motor is rotated at low speed, a CPU 14 gives U phase with an excitation signal while giving W phase with a signal having phase different from the excitation signal of U phase at 60 deg.. When the brushless motor is turned at high speed, the excitation signal of three phase of U, V, W is given. A low-speed excitation system and a high-speed excitation system are installed for driving the brushless motor at low speed and at high speed at that time, but the motor can be constituted simply because the low- speed excitation system generates a revolving magnetic field in two phase and the brushless motor is driven. Accordingly, the three-phase brushless motor can be driven in a wide rotational region by simple constitution.

Title: Copying machine
Inventor: SUZUKI SEIICHI
IPC: G03G15/04
Filed: 1982-06-12
Abstract: PURPOSE:To prevent copy deviation due to an impact generated during returning operation, by controlling the starting of the return of an optical system in accordance with the length of copying paper in a paper feeding direction. CONSTITUTION:The optical system 42 moves forth as shown by an arrow B to make a scan on an original and the distance of this forward movement is controlled by counting a reference pulse signal. For example, when the forward movement of the optical system 42 is detected by a sensor 50, in other words, once a paper feeding roll 15 starts rotating, the counting of the reference pulse signal is started. When the counted value of a pulse signal generated until a sensor 17 detects the rear end of copying paper is greater than a specific value, namely, when the length of the copying paper in the paper feeding direction is longer than the conveyance path length between the transfer position and fixing and clamping part of a photosensitive drum 3, the backward movement of the optical system 42 is inhibited for a specific time corresponding to the detected length of the copying paper. Therefore, transfer deviation due to an impact during the backward movement of the optical system 42 is not caused.

Filed: 1984-05-18
Abstract: PURPOSE:To obtain a reciprocal actuator having low transmission loss by transmitting the reciprocal moving force due to the fluid pressure of piston through the pressing force of plural ball groups tightly arranged in a curved path to a driven member. CONSTITUTION:Upon supply of pressure fluid to the cylinder chambers 1A, 1B at the opposite sides of piston 2 through changeover of valve, the piston 2 is reciprocated in the arrow direction X-X. The moving force of piston is transmitted through ball group 6 to a driven member 3 to reciprocate said member in the arrow direction Y-Y along fixed path. Said reciprocation is transmitted to a movable member such as a door thus to perform opening/closing operation. Since the driving force of piston is transmitted efficiently, desired motion performance can be maintained reliably.
