Abstract: PROBLEM TO BE SOLVED: To reduce torsional vibration of a vehicle body without any great increase in weight. SOLUTION: In an open car type automobile, in which the upper side of a body is opened, rear wheels 2 work as driving wheels. A power unit 6 constructed of an engine 7 and a transmission 8 and arranged in the vehicle body front part is supported by means of a front cross member 5 via a pair of left and right elastic mounts 9. In the vehicle body rear part, a rear differential case 12 is supported by the rear cross member 11 via a pair of left and right elastic mounts 13. The transmission 8 and the rear differential case 12 (a gear inside the case 12) are connected together by means of a propeller shaft 15, and at the same time, they are firmly connected together via a connecting frame 16.  The elastic mounts 13 are designed to be hard while the elastic mounts 9 are designed to be soft, and the power unit 6 functions as a mass body for a dynamic damper oscillated in the vertical direction while using the vicinity of the rear differential case 12 as an oscillation axis, so that vehicle body torsional vibration is reduced at 15-20 Hz.

Filed: 1989-12-05
Abstract: PURPOSE:To obtain the title member improved in resistance to heat and corrosion by coating the surface of an alumina substrate with each specific slurry in a desired number of layers followed by roasting. CONSTITUTION:Firstly, several kinds of slurry 10-1000cPs in viscosities are prepared by mixing fine zirconia 2-20mum in granular size, fine alumina 1.5-44mum in granular size and 1-8wt.% of a binder (e.g. PVA) with the molar ratio Al2O3/ ZrO2 reduced successively and the viscosity adjusted. Second, the surface of an alumina substrate is coated with one of the above slurries with larger molar ratio Al2O3/ZrO2 so as to be 10-50mum of thickness followed by drying, and the resulting surface is then further coated with a second slurry with somewhat smaller molar ratio of Al2O3/ZrO2 so as to be 10-50mum thick followed by drying. In this way, cumulative coating in 5-10 layers is made so that the uppermost layer represents a genuine alumina coating layer with the whole thickness between 50 and 300mum. Thence, the resultant alumina substrate is raised in temperature to 1400-1600 deg.C at a rate of 50-250 deg.C/hr and held for one hour to carry out roasting.

Title: Digital still camera
Inventor: KIMIZUKA CHIKADA
IPC: H04N5/907
Filed: 1995-12-01
Abstract: PROBLEM TO BE SOLVED: To evade making picked-up image writing impossible due to the block destruction of a flash memory by permitting the whole data in a memory to be read-only in the case where all the spare blocks are used up. SOLUTION: A flash memory controller 20 connects a flash memory card to a main microcomputer 8. When the block in the memory is destroyed at the time of written picture data in the flash memory, picture data written in the defective block is read from a frame memory 9 again and rewritten in another spare block in the flash memory. In the case where all the spare blocks are used up after executing such rewriting, the file attribute of a file allocation table is changed so as to permit the whole flash memory to be read-only. Then, writing after that is prohibited in the main microcomputer 8.

Abstract: PROBLEM TO BE SOLVED: To provide an unbalanced-to-balanced converter circuit which makes themselves low voltage and does not degrade the balancing of a balance signal so much even when a frequency rises. SOLUTION: In an unbalanced-to-balanced converter circuit 2 which consists of one FET, condensers and resistances and unbalanced-to-balanced converter circuits 3 and 4 which have the same structure, the circuits 3 and 4 are separately connected to two outputs of the circuit 2, and four outputs of the circuits 3 and 4 are connected with in-phases connected to each other and anti-phases connected to each other and output. With this, the deterioration in balancing can be reduced even in a high frequency by canceling the deterioration in balancing in a high frequency of an unbalanced-to-balance converter circuit that is a preceding stage with an unbalanced-to-balance converter circuit that is a subsequent stage. Also, it is possible to make power voltage low voltage by structuring each unbalanced-to-balance converter circuit with one FET.
