Title: Elevation-controlling mechanism of air jet nozzle unit for air jet type machine for soil improvement
Inventor: SASAI AKIRA
IPC: A01B35/00
Filed: 1989-12-22
Abstract: PURPOSE:To make an electric control circuit unnecessary and improve maneuverability by carrying out elevation of an air nozzle unit and driving of a driving pipe or drawing thereof in a prescribed time lag. CONSTITUTION:When the oil pressure of an oil-hydraulic cylinder 402 for elevation exceeds the set value of the first sequence valve 711, the lower chamber of an oil-hydraulic cylinder 513 for drawing is opened in order to return the pressure oil in the lower chamber to an oil-hydraulic tank 210. Driving of the driving pipe is started in a state in which an air jet nozzle unit is in contact with the ground. Elevation of the air jet nozzle unit is started after completion of air jet operation and after drawing of the driving pipe out of the ground by an action of the second sequence valve 718.

Title: Piston ring
Inventor: ONODA MOTONOBU
IPC: C23C28/04
Filed: 1990-11-30
Abstract: PURPOSE:To bring high integrated performance into full play even under severe service conditions by making up a compound dispersion plating layer in dispersing a hard grain of specified grain size in a nickel alloy containing boron at the specified rate at a specified volumetric ratio, and constituting the coat with either of those of metal's nitride, carbide and oxide. CONSTITUTION:A piston ring has a coat 3 consisting of either of a metalnitride, a metal carbide and a metal oxide formed by means of a physical vapor-phase vacuum evaporation process, on its peripheral sliding surface, and thereby there is little in a friction loss and an attacking property against a counter member cylinder is low. This coat 3 is installed on a compound dispersion plating layer 2 set up on a base material (1) surface. This compound dispersion plating layer 2 is made up of dispersing a hard grain of 0.1-10mum in grain size in a nickel alloy containing boron at the rate of 5-30% in volumetric ratio, and it is excellent in abrasion resistance while scuffing resistance is sharply improved. Therefore, supposing the coat 3 is worn out and a part of the plating layer 2 is exposed, they are compensated by these protective elements.

Title: Thermal recording material
Inventor: TANAKA YOSHIMASA
IPC: B41M5/333
Filed: 1989-12-26
Abstract: PURPOSE:To obtain a thermal recording material having excellent gradation separability by adding 2, 2-bis(p-hydroxyphenyl) propane to a thermal recording layer as a coupler and further adding di(p-methylbenzyl)oxalate and a stearamide emulsion thereto. CONSTITUTION:As an org. acidic substance developing the color of a dye precursor under heating, 2, 2-bis(p-hydroxyphenyl) propane is used. Di(p-methylbenzyl) oxalate is used in the thermal color forming layer containing this coupler as a sensitizer in order to highly develop excellent effect in high sensitivity and high gradation separability and a stearamide emulsion is further combined with the sensitizer. Di(p-methylbenzyl)oxalate acts as a color forming accelerator and generates an m.p. falling phenomenon by the mixing with the org. acidic substance and accelerates the reaction with the dye precursor at temp. lower than the respective melting points of both of them. Further, the stearamide emulsion is considered to be high in the compatibility with the dye precursor and 2, 2-bis(p-hydroxyphenyl) propane and the reaction of the dye precursor with the coupler is accelerated in the heated molten emulsion and reaction sensitivity is further enhanced.

Title: Positioning table
Inventor: MONZEN MASAHIKO
IPC: H01L21/68
Filed: 1987-12-28
Abstract: PURPOSE:To make it possible to employ a positioning table of a small size by dividing the light interrupting section of a glare protection plate restricting the moving range of the positioning table into plural numbers so as to be mounted on a X-table, and thereby restricting the moving range by a plurarity of photo sensors. CONSTITUTION:Photo sensors 10 through 13 composed of light emitting sections and light receiving sections are mounted onto a base 1 in such a way that the light axis of each sensor is located at the center of each circular arc of the circular arc sections A1 through A4 of glare protection plates 5a and 5b. And photo sensor 10 functions to restrict the movement corresponding to one quarter of the moving range of a resting table 4, similarly the photo sensors 11 through 13 function in such a way to restrict the movement corresponding to one quarter of the moving range. Hence, the moving range of the resting table 4 is restricted within a circle by placing the table in such a way as to correspond to four photo sensors 10 through 13 and four projections 6 through 9 respectively. Thus, when the circle A restricting the moving range of the table 4 is divided so as to form a light interrupting plate for arranging four photo sensors, the positioning table can thereby be made small in size.

Title: Radio receiver
Inventor: GO YASUNAO
IPC: H03J7/28
Filed: 1989-12-25
Abstract: PURPOSE:To select the near distance sensitivity mode and the remote distance sensitivity mode surely and efficiently by providing a sensitivity switching control means and outputting a reception sensitivity switching command signal to a reception sensitivity switching means when a channel selection search operation is circulated in a receptible frequency band. CONSTITUTION:A channel selection search means applies sequential cyclic search to a transmitted radio wave frequency from each broadcast station set at a predetermined interval. The cyclic search operation is monitored by a sensitivity switching control means 10. The sensitivity switching control means outputs a reception sensitivity switching signal to a reception sensitivity switching means 14 when the cyclic search operation is circulated in a receptible frequency band, that is, the end frequency in the search direction is restored to the frequency of the original search start point again. The reception sensitivity switching means 14 uses a reception sensitivity switching signal SCH as a trigger to switch the reception sensitivity mode from the near distance sensitivity mode LOC into the long distance sensitivity mode DX or vice versa. Thus, the sensitivity is automatically switched together with the cyclic search operation.

IPC: H01L21/336
Filed: 1991-11-27
Abstract: PURPOSE:To make an even crystal growth in the film thickness dirction of silicon when an amorphous silicon film is crystalized. CONSTITUTION:A lower layer insulating film 12 comprising oxide is deposited on an insulating substrate 11 and then an amorphous silicon film 13 is deposited on the film 12, next an upper layer insulating film 15 comprising silicon nitride is further deposited on the film 13. Next, when the whole surface is irradiated with excimer laser (a), the temperature on the surface of the amorphous film 13 falls to the minimum at the time when the whole body of the amorphous silicon film 13 is melted down to be gradually raised toward the lower part. Meanwhile, the thermal conductivity of the silicon nitride is larger than that of silicon oxide, accordingly, the calory dissipated from the surface of the amorphous silicon film 13 to the upper layer insulating film 15 is larger than that from the rear surface of the amorphous silicon film 13 to the lower layer insulating film 12. Resultantly, the solidification starts from the surface side only of the amorphous silicon film 13 so that even crystal growth may be made in the film thickness direction of silicon.
