Title: Piston for internal combustion engine
Inventor: OZEKI HIROSHI
IPC: F02F3/00
Filed: 1999-04-09
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration in mechanical strength and influence on the service life of a piston by forming a rib projection part on the rear surface side of an oil groove, which corresponds thereto. SOLUTION: A piston 10 comprises a crown part 10a, a skirt part 10b extending downward therefrom in a thin-plate shape, a rib projection part formed on the surface thereof protruding to the rear surface side, and a groove part formed by denting a front surface side corresponding to the rib projection part. Since the groove part formed on the skirt part 10b surface has a simple windowpane shape, spread over the entire skirt part 10b surface, when an internal combustion engine starts, oil is actively supplied to the surface thereof without generating local stress on the piston 10 surface. The groove part spreads over the entire surface of the skirt part 10b, with vertical and lateral grooves T1-3, Y1-3 communicating with each other, so that the oil scavenged and stored in the groove part circulates in the groove part and is supplied smoothly and widely in flat parts 12, 12a, 12b surrounded by the groove part.

Title: Fully automatic plating device
Inventor: ODAGAKI MITSUZO
IPC: C25D21/00
Filed: 1986-05-02
Abstract: PURPOSE:To make a uniform plating treatment with good productivity by circulating treating liquids for bar-shaped objects to be plated always gently and moving the objects to be plated horizontally except at the time when the objects bestride plating cells. CONSTITUTION:The respective treating liquids are gently circulated by many relatively shallow liquid tanks (10l, etc.) and storage tanks (11l, etc.) provided below the tanks. The bar-shaped objects to be plated are then successively placed to L-shaped hooks 21 positioned below the chain traveling at a constant speed and are thereby horizontally supported. The objects to be plated are horizontally guided and moved by lower guides 17a, 17b except at the time when the objects bestride the adjacent liquid tanks (10l, etc.) and are successively immersed for the required time in the respective liquid tanks (10l, etc.), by which the pretreatments such as degreasing, rinsing, pickling, electrolyzing, rinsing and acid neutralizing are executed. The objects are then subjected to a plating treatment then to post treatments such as rinsing, unichrome-plating and rinsing. Electricity is fed to the objects to be plated through the hooks 21 in the electrode treatment and plating treatment. The uniform treatment is thereby executed with the treating liquids always held at the constant liquid level in the shallow liquid tanks (10l, etc.).

Abstract: PURPOSE: To set off the elongations of a spindle and feed screw caused by thermal displacement with the elongations of a spindle head and a receptacle table by forming the receptacle table from a metal material having a greater coefficient of thermal expansion than the materials of the spindle and feed screw. CONSTITUTION: The direction in which a spindle head 4 and receptacle table 10 elongate is opposite to the direction in which a spindle 8 and ball screw elongate, so that the elongations are set off by each other, and the thermal displacement at the spindle nose 8a can be minimized when the thermal displacement 5A of the part with a total length A of the spindle 8 and ball screw is equal to the thermal displacement 3B of the spindle head 4 and receptacle table 10. Therefore, the receptacle table 10 should be made of a metal material such as aluminum having a greater coefficient of thermal expansion than that of iron material with which the spindle 8 and ball screw are formed.  If the ratio of the coefficient of thermal expansion of the material of spindle 8 and ball screw to the material of receptacle table 10 is 1:2, the two are set off by each other, provided that the elongation of the spindle head 4 is ignored and a simplification as the temp. being uniform is introduced.

Title: Scanning probe microscope and its sample observation method
Inventor: SUGIZAKI KATSUMI
IPC: G01B21/30
Filed: 1997-04-04
Abstract: PROBLEM TO BE SOLVED: To directly find the interaction between a probe and the surface of a sample to be observed correspondingly to the distance between the probe and the surface of the sample while the occurrence of jump-in is prevented without giving any restriction to the sample. SOLUTION: A cantilever 1 is provided with a lever section 1b with a thin film type actuator. A deflection control section 9 gives a drive signal to the thin film type actuator so that the deflecting amount of the lever section 1b of the cantilever 1 may become zero based on a deflection detecting signal indicating the deflecting amount of the lever section 1b from a signal processing circuit 8. A scanner control section 5 separates a sample 3 from the probe 1a of the cantilever 1 after gradually bringing the sample 3 nearer to the probe 1a by giving a drive signal to a tube type scanner 4.  During the course of this process, a data preparing section 10 successively fetches a drive signal given to a scanner control section from the scanner control section 5 and the drive signal given to the thin film type actuator from the deflection control section 9 by correlating the signals with each other.

Title: Cylinder direct injection internal combustion engine
Inventor: NAKAMURA MAKOTO
IPC: F02D41/02
Filed: 1996-04-25
Abstract: PROBLEM TO BE SOLVED: To reduce NOx emitted which poses problems in employing injection at the compression stroke of an engine, as well as improve torque which functions as an important factor in employing injection at the suction stroke. SOLUTION: In a cylinder direct injection internal combustion engine, under high load fuel is injected at the suction stroke, and under medium load fuel is injected at the compression stroke. The engine is provide with a variable valve system which successively controls the opening or closing timing of an intake valve so as to be varied. In the case of injection at the compression stroke, the intake valve opening timing IVO is advanced and its closing timing IVC is retarded, as a result of which more exhaust gas remains in the cylinder to reduce NOx emitted. In the case of injection at the suction stroke, however, the intake valve opening timing IVO is retarded and its closing timing IVC is advanced, as a result of which the returning of air-fuel mixtures is suppressed to raise the charging efficiency and improve the torque.

Title: Optical disk reproducing device
Inventor: OGAWA HIROSHI
IPC: G11B7/005
Filed: 1993-04-06
Abstract: PURPOSE:To remove a low frequency noise due to the contamination, birefringence and optical ununiformity in a reproducing signal of an optical disk and to stabilize the operation even using a single mode laser module. CONSTITUTION:A laser beam is modulated with high frequency by means of a laser modulating circuit 2. An optical disk 6 is irradiated with the modulated laser beam. A returned light beam from the optical disk 6 is detected by a photodetector 8. Only the modulated component is extracted out of the output of the photodetector 8 by means of a band pass filter 11. The output of the band pass filter 11 is detected by a detecting circuit 12 and a base band signal is obtained. Consequently, a low frequency noise is completely removed. Since the laser beam is modulated, the laser module with a single mode is usable.
