Patent JP-S6037142-A (JP)
Title: Semiconductor device
Inventor: WADA YASUO
IPC: H01L21/762
Filed: 1983-08-10
Abstract: PURPOSE:To improve characteristics in a fine device in small thickness, particularly, 1mum or less, and to form the semiconductor device having the high density of integration by making impurity concentration in a diffusion layer high in the bottom of a groove and a section in the vicinity of the bottom and low in a section in the vicinity of the surface. CONSTITUTION:B diffusion layers 5 in 5X10<16>cm<-3> concentration are formed to the bottoms of grooves and side surfaces in the vicinity of the bottoms and B diffusion layers 6 in 5X10<15>cm<-3> concentration to sections in the vicinity of the surfaces of the side surfaces in a region 2, which is formed to a Si substrate 1 of a P type (100) face and 10OMEGAcm and to which a device separated by the grooves must be shaped, and the grooves are buried with an insulator 4. Impurity concentration in the vicinity of the surface is made low, and a narrow channel effect is prevented. On the other hand, a device having high impurity concentration has the higher effect of a channel stopper, and the leakage currents of a channel must be brought to 10<-14>A or less per one element. Accordingly, sections in the vicinity of the bottoms of the grooves must be doped in high concentration. The high-concentration impurity layer is useful for improving the performance of a fine device because it is of use for preventing the punch-through of the device.

IPC: F02B75/18
Filed: 1985-07-01
Abstract: PURPOSE:To reduce the size of a whole engine and prevent a power from being wastefully spent resulting from driving of an inertia rotor through elimination of the inertia rotor, by a method wherein generators are respectively coupled to the end parts of two crank shafts. CONSTITUTION:Generators 15 and 16 are mounted to the vicinity of the surroundings of end parts 12 and 13 of crank shafts 5 and 6, respectively. The generators 15 and 16 are provided with stator coils 20 and 21, magnets 22 and 23, and fly wheels 24 and 25, respectively. With an engine rendered operative, the generators 15 and 16 are actuated through rotation of fly wheels 24 and 25 with the aid of crank shafts 5 and 6, and a power is fed to each part therefrom. This causes about equalization of the inertia mass of the crank shaft 5 including the fly wheel 24 with the inertia mass of the crank shaft 6 including the fly wheel 25. This prevents an unreasonable force from being exerted on a primary gear coupling the crank shafts 5 and 6 with an output shaft, and enables elimination of an inertia rotor.

Inventor: HAMAZAKI MIKIHIKO
IPC: G01N21/90
Filed: 1978-11-25
Abstract: PURPOSE:To exactly inspect defects on the bottom of a bottle by irradiating a light toward the bottom surface of the bottom and detecting the reflected light from the defects such as kinks or air bubbles existing in the bottom interior by a detector disposed oppositely to the bottom of the bottle. CONSTITUTION:The light from a light source 2 is transmitted through the side wall of the bottom of a bottle into the bottom interior and reflected on the boundary portion of defects 6 such as kinks or air bubbles or the like in the bottom, and partly reflected to any of photocells 3 disposed in numerous number on a bearer 5 for the bottle to thereby produce an abnormal signal therefrom. If there is no defect in the bottom of the bottle, no reflected light is transmitted to the photocells 3 to thus produce no abnormal signal. Since the light is reflected different in its direction and angle according the position and angle of the kink, it is necessary to scan the light to the bottle to be inspected by altering the position of the bottle to be inspected. This configuration can exactly inspect readily the defects such as kings, air bubbles in the bottom so as to prevent in advance trouble to be occurred after filling the bottle.

Title: Pressure-force converter
Inventor: OOIWA AKIRA
IPC: F16J10/02
Filed: 1982-08-24
Abstract: PURPOSE:To prevent mechanical contact friction between a piston and a cylinder under a working condition and to perform steady and highly sensitive pressure-force conversion, by forming a proper taper on the piston or cylinder. CONSTITUTION:Taper is formed on a cylinder 1 or a piston 2 such that a clearance 4 increases on the high pressure side 3a and decreases on the low pressure side 3b. In case of the piston 2 being positioned in the center of the cylinder 1, the pressure distribution in the clearance 4 is uniform at any point of a periphery, and the radial component, of a force exerted on the piston 2 becomes zero. In case of the piston 2 being moved in parallel and being brought to an eccentric state, the pressure distribution on the side 4a, where the clearance 4 decrease, is different from that on the side 4b where the clearance increases. The average of pressure exerted on the clearance 4a side increases and the average of pressure exerted on the clearance 4b side decreases. Namely, a force is exerted on the piston in the direction in which eccentricity decreases. This restoring force is in proportion to the magnitude of the eccentricity and the pressure difference between both end faces. The provision of tapered clearance causes a restoring force to be exerted on the piston so that the piston is maintained in a vertical state at the center of the cylinder, and prevents the piston from making mechanical contact with the cylinder.

Abstract: PURPOSE: To form a work body into being compact in size by constituting it from slide motion member fitted in a columnar body, a speed reducer consisting of a worm and a worm gear, and an output shaft sprocket or pinion in mesh with a chain or rack of the columnar body. CONSTITUTION: Rotation of a handle 10 rotates a worm 53 via an input shaft 52, thereby rotating a worm gear 55 in mesh with this worm at a set reduction ratio. Likewise, rotation of this worm gear 55 rotates a sprocket 6 at the same revolution via an output shaft 54, and this rotating work gear is engaged with a chain installed in a square steel 2, sliding a slide motion member 4 along this square steel 2. If this slide motion member 4 arrives at the set position, and the rotation of the handle 10 is stopped, the worm gear 55 is engaged with the worm 53 and thereby its rotation checked, and it is held at the stop position. In consequence, the slide motion member 4 is made slidable along one piece of the square steel 2, and thus it is formable into being compact in size.
