Title: Layer-scavenging two-cycle internal-combustion engine
Inventor: JIYO HANDOU
IPC: F02B17/00
Filed: 1983-04-06
Abstract: PURPOSE:To remarkably reduce the blowby loss of fuel components by utilizing an eddy chamber provided on a scavenging passage to separate the scavenged mixture into the air, thin mixture, and dense mixture in the scavenging stroke of a spark ignition-type two-cycle internal-combustion engine. CONSTITUTION:The air flow-controlled by a butterfly valve 11 and sucked into a crank chamber 4 through an intake hole 12 during an intake stroke flows into a cylinder 10 from a scavenging hole 9 through a scavenging passage 8 during a scavenging stroke to scavenge the combustion gas. Part of the air flows into an eddy chamber 2 through a communicating passage 3 to generate an eddy current. When the liquid fuel is injected into the eddy chamber 2 from a low-pressure fuel injection valve 7, the liquid and a gas component having large specific gravity are distributed at the peripheral section of the eddy and the gas component having light specific gravity is distributed at the center of the eddy. Accordingly, if the center of the eddy chamber 2 and a scavenging hole 13 are communicated, the thin mixture flows into the cylinder from the scavenging hole 13 through an outflow port 5 from the center of the eddy chamber 2 and a scavenging chamber 14, and if the outflow port 6 at the periphery of the eddy chamber is communicated to the scavenging hole 13, the dense mixture flows in through a scavenging passage 15 and a scavenging hole 16.

Title: Sample polishing apparatus for transmitting type electron microscope
Inventor: NISHIO NAOHARU
IPC: G01N1/32
Filed: 1989-03-13
Abstract: PURPOSE:To read the polishing amount of a sample during polishing by measuring the electrostatic capacitance between a fixed electrode which is fixed to a cylinder and a variable electrode which is relatively displaced with respect to the fixed electrode that is guided with the cylinder in synchronization with the polishing action of the sample. CONSTITUTION:A fixed electrode 10a is provided at the bottom part of a cylinder 9. A movable electrode 10b is attached to a cylinder 11 that is linked to an arm 4 so as to face the electrode 10a. The electrodes 10a and 10b are connected to an electrostatic capacitance detector 12, and a computer 13 and a display 14 are connected. As the polishing of a sample advances, the piston 11 is lowered with the descent of the arm 4. The electrostatic capacitance between the electrode 10b and the electrode 10a is detected with the detector 12. The distance between the electrodes 10a and 10b is computed in the computer 13 based on the electrostatic capacitance value and displayed on the display 14. The polishing amount of the sample can be measured during the polishing based on the displayed amount and the descending amount of the arm 4.

Inventor: ARIMOTO TAKEO
IPC: F16C19/36
Filed: 1978-05-20
Abstract: PURPOSE: To prevent roller contact or retainer noise by applying as a tapered roller angle the difference angle between an external and an internal wheel track surface angles which changed by fitting.  
     CONSTITUTION: When the angle of a tapered roller 7 is sought, the angles of an internal and an external wheel track surfaces α', β' obtained by expansion and deformation due to the fitting of the internal and the external wheels 5, 6 are detected and the difference angles α'-β' is let to be the tapered roller angle. Thereby the fitting dimension of the internal and the external wheel track surfaces and that of the tapered roller 7 are similar and it is possible to fit them adequately. In this way irregular roller contact, retainer noise are protected and longer life can be obtained.

Title: Tester for rubber roller
Inventor: KAMINAGA RETSU
IPC: G01N19/04
Filed: 1983-04-08
Abstract: PURPOSE:To enable the easy determination of whether the bonded part of rubber and metal is excellent or not, by detecting elastic waves generated by a slight exfoliation in said bonded part and by subjecting said elastic waves to waveform processing. CONSTITUTION:When a load applied to a metal fitting 22 of a body to be tested and increased gradually reaches a certain level, a slight exfoliation is generated in the bonded part of rubber 20 of a said body and the metal fitting 22 thereof. Elastic waves are generated at this time. Since the outputs of these elastic waves are very small, they are amplified by an amplifier 26, and output signals therefrom are monitored by a synchroscope 27. The elastic waves are generated discontinuously on the occasion since the exfoliation in the bonded part is irregular, and thus it is hard to determine a real elastic wave from the raw waveforms thereof even by the monitoring by said synchroscope. Therefore, all the elastic waves which are caught are stored in a memory of a waveform processing device 28 and subjected to operations, and the result thus obtained is displayed on a CRT of the device 28.

Abstract: PURPOSE:To cover a metallic material with weak compressive force and in a single stage by subjecting a base material on which a covering material is put and said covering material to diffusion welding simultaneously while molding the same compressively in a nonoxidative atmosphere. CONSTITUTION:A pipe 12 consisting of a corrosion resistant material is put on a bar 11 consisting of a conductive material and is placed on a lower pressurizing jig 10. The inside of a vacuum chamber 13 is evacuated to vacuum, whereafter a heater 14 is switched on. When the bar 11 and the pipe 12 are heated up to the temp. necessary for diffusion welding, an upper pressurizing body 15 is moved downward and prescribed pressurizing force is exerted to subject the bar and the pipe simultaneously to compression molding and diffusion welding. The atom diffusion of the bar 11 and the pipe 12 is progressed by this pressurizing force, while the bar 11 creeps in the transverse direction and fills the inside of the pipe 12. When the jig 9 contacts with the stoper part 17 of the jig 10, the creep stops and the diffusion progresses in this state until joining is completed.
