Patent JP-S59176494-A (JP)
Title: Scroll compressor
Inventor: INABA TSUTOMU
IPC: F04C29/02
Filed: 1983-03-26
Abstract: PURPOSE:To reduce the rising oil level by providing a suction gas passage between the outer periphery of a motor and a frame and inverting the suction gas introduced into a motor chamber upward near the lower end of the frame to separate the oil. CONSTITUTION:The suction gas introduced into a motor chamber 19 passes downward through a passage 29 and is inverted in a demister 30 and is sucked into a suction chamber through a passage 26. Therefore, the flow quantity of the suction gas hitting an oil sump 23 is small and the flow speed is also small, thereby the oil is hardly scattered when being hit, and even if part of the oil scattered due to the rotation of a crank shaft 14 is carried away by the suction gas, the oil is deposited to the demister 30 and separated when the gas passes through the demister 30.

Title: Production of piezoelectric vibrator
Inventor: KANBARA MASAHARU
IPC: H01L41/39
Filed: 1979-04-26
Abstract: PURPOSE:To produce a small-loss piezoelectric vibrator by forming a structure, where piezoelectric substance layers and conductor layers are laminated alternately, through a specific process. CONSTITUTION:Mask 31 having pattern 32 is put on base stand 30 of the piezoelectric substance, and slurry of pieszoelectric porcelain materials is coated onto pattern 32 by squeeze 33. After this slurry is dried to form piezoelectric substance 10, electrode layers 11 and 12 of silver paste are formed similarly to above. Their forms are set properly according to a required electrostatic capacity value by mask 31 of a plane-plate type, mesh type and so on. After repeating two processes above to constitute a lamintating material, this material is cut into a desired size in parallel with the plane, and cut materials are calcinated. Next, a DC voltage is applied across respective electrodes to polarize piezoelectric substance 10. In this case, since the piezoelectric substance is divided into thin layers, it is sufficient if a comparatively low voltage is applied. After that, conductive layers 13a-13c are stuck to laminating faces of the laminating material, and electrode layers are connected electrically for every layer to constitute an inter-digital electrode, thus obtaining a low-loss piezoelectric vibrator.

IPC: G06F11/28
Filed: 1987-03-05
Abstract: PURPOSE:To improve the program test/debug efficiency as well as the program reliability/productivity by measuring a test coverage only the corrected areas of a program. CONSTITUTION:A memory 11 storing a source program is provided together with a memory 12 storing an executing program, a memory 13 storing the corrected program source information, and a memory 14 storing the coverage information.

Then the test coverage data is separated into a part corresponding to a corrected area and a part corresponding to an uncorrected area. The coverage information stored in response to both corrected and uncorrected areas are outputted after replacement and addition. It is possible to obtain a function equivalent to a case where all test coverages are measured again when a program receives a correction. Then the test debug efficiency and the productivity are improved for a program.

Title: Recording mechanism using ink
Inventor: TSUDA TSUYOSHI
IPC: G01D15/16
Filed: 1979-04-27
Abstract: PURPOSE: To give effect to smooth recording by allowing a vibrator, provided to the tip of a pen, to vibrate the pen tip itself.  
     CONSTITUTION: Main pen body 1 made of a magnetostrictive material (e.g., stainless steel of ANSI406 or 405) is filled with ink 3. Coil 2 is provided around the outer circumference surface of pen body 1. Once applied with an alternating current, coil 2 is magnetized by a direct current being deviated from pen body 1 and the alternating current causes magnetostrictive vibration axially. Consequently, the pen tip contracts in parallel to the direction in which ink 3 flows and ink 3 itself at the pen tip vibrates with efficiency. Since an ultrasonic wave is transferred via even the pen-tip metal in this way, the ink at the pen tip part can efficiently be applied with relative vibration without loss, so that smooth recording will come into effect.
