Filed: 1979-04-04
Abstract: PURPOSE: To minimize an efflux of oil by a method wherein a high-pressure gas leaking out into a crank case is returned to a suction pipe through an oil separator and also the oil is returned to the crank case.  
     CONSTITUTION: A high-pressure gas leaking out of a compression space 24 into a crank case 27 is led to an oil separator 29 from a coupling pipe 28 for gas efflux which is through to the crank case 27 of a cylinder block 9 and after oil is separated, it flows into a suction pipe 31 through a coupling pipe 30 for gas return and then reaches a suction chamber 20. The separated oil passes a pipe 32 for oil return and is fed back into the crank case 27. The oil is therefore prevented from flowing into the compression space 24, and since the oil scarcely flows out into a system, the oil in a compressor 1 can be kept in proper quantity.

Abstract: PURPOSE:To measure a minute size precisely by detecting the position of a kink point in change in intensity of a reflected-light intensity pattern, and measuring the size based on the amount of deflection when the light is deflected between the kink points. CONSTITUTION:Laser light 100 emitted from a laser light source 1 is deflected in the directions of A     B on the surface of an object to be measured 3 through an optical system 2. Then, the laser light reflected from the object to be measured 3 is inputted into a light receiving part 5 as reflected light 120 through the optical system 2. Then, the reflected light 120 is received by a photodetector which is split into two light receiving regions 152 and 154 at a central part 150 in the light receiving part 5. Voltages which are proportional to the amounts of the reflected light beams generated in the light receiving part 5 are stored in a memory part 7 through an A/D converter part 6. The intensity-change characteristics of reflected-light-intensity patterns 173 and 175 formed in the memory part 7 are operated in first and second operating parts 8 and 9. The intensity of the difference between the patterns 173 and 175 is computed in a differential intensity operating part 10. In a size operating part 11, the size is computed based on a deflection control voltage corresponding to the kink position and the peak position.

Title: Preparing method for type head
Inventor: WADA HIROSHI
IPC: B41J1/30
Filed: 1979-04-06
Abstract: PURPOSE: To raise the precision of fitting of a type head to a selecting axis and facilitate the preparation by engaging insert arms with an insert-retaining pin and molding all in a unitary body.  
     CONSTITUTION: An upper mold 17 being removed, an insert 11 is fitted to an insert-retaining pin 15, a chipped part 16 being pressed against a plane 12. Each arm 13 is engaged with the insert-retaining pin 15. Under the condition, the upper mold 17 is put on a lower mold 14 and the synthetic resin is poured into the molds, thereby a type head being formed. Accordingly, the insert 11, being tightly pressed against the insert-retaining pin 15, is molded solidly with the resin. Therefore, the type-head being fitted to a selecting axis, the plane plate 12 is stuck fast to the chipped part of the selecting axis, while each arm 13 being stuck to the peripheral surface on the opposite side to the chipped part of the selecting axis. In this way, the part requiring the anti-abrasiveness is to be formed by a contact of metallic parts, which improves the anti-abrasiveness. In addition, since the sufficient fitting precision can be obtained by processing the insert-retaining pin with high precision, the processing can be facilitated.

IPC: G01C19/5628
Filed: 1984-03-02
Abstract: PURPOSE:To achieve the optimum sensitivity without the effects of the vibration and acceleration of a moving body attaching part, by supporting a base table around the center of gravity of a tuning fork, which approximately agrees with the center of gravity of the base table, and making the vibrating frequency of the tuning fork approximately equal to the resonance frequency obtained by the specified expression. CONSTITUTION:Two legs 1-5', which hold an attaching part 30' of a piezoelectric element 30 for detection, are extended from both ends of a counterweight part 1-5. The center of gravity of a vibrating system comprising a tuning fork 1, an element 30 and the like is made to agree approximately with the intersection of the Z axis and the X axis. A tubular body 41 is fixed to an L shaped metal 43 on a base table 44 through an elastic member 42. The tuning fork 1 and the like are held in the tubular body 41 in an airtight manner. The resonance frequency f0 around the Z axis satisfies the expression in the Figure, where IS and IF are the inertial moments of the supporting part and the tuning fork, and K is the spring constant of the element 30. The value of f0 is made approximately equal to the vibrating frequency of the tuning fork fF. Thus the effects of the vibration and acceleration of the attaching part of a moving body, whose angular speed is to be measured, are not received. Since the two vibrating frequencies are made approximately equal, the optimum sensitivity can be obtained.
