Patent JP-H022177-A (JP)
Title: Field effect transistor with floating gate
Inventor: NAKATANI YOSHIHARU
IPC: H01L29/78
Filed: 1988-06-14
Abstract: PURPOSE:To reduce variation in electric characteristics and to improve producibility by separating a gate into a fixed gate and a floating gate through a low density layer of a polarity opposite to that of a gate at a channel section. CONSTITUTION:At an enhancement type power MOS FET, the gate is separated into a fixed gate PG and a floating gate P at the lower part of a channel through a low density layer N- of a polarity opposite to that of the gate. This separation is made by lamination of a low density layer N- through epitaxial growth. The distance therebetween is at most twice as much as a depletion layer (d). In case of incidence X, light of energy h is directed externally through a floating gate to generate pairs of electron and hole. Electrons flow out to a drain side D and holes flow partially to the fixed gate PG and partially to the floating gate P to generate photocurrent (Iop). The photocurrent (Iop) reaches to the gate P where holes are collected. This increases the potential of the floating gate P to form a channel.

Title: Detecting device for stack
Inventor: TABATA YOSHIMI
IPC: B65G65/06
Filed: 1982-08-27
Abstract: PURPOSE:To ensure the safety of a sensor for detecting a stack in a stacker reclaimer by a constitution wherein an arm is supported rotatably on a boom, a lever is also supported rotatably on the boom, the lever is linked to the arm rotatably simultaneously, and the sensor is supported in suspension on the projecting end side of the arm. CONSTITUTION:At the time of stacking operation, a lever 5 is rotated to the right around a shaft 17, and a stopper pin 6 is inserted into holes 18 and 19. Thereby the rotation to the right of the lever 5 makes an arm 2 rotate to the right together with a rotating shaft 12 through the intermediary of a link 4 and a lever 16. Since the rotating arm 2 is balanced in weight with a balance weight at a prescribed rate at this time, an operation of rotating the lever 5 and the positioning of the holes 18 and 19 can be performed with ease. Since the lever 5 is fixed onto the boom 9 side by the stopper pin 6, the arm 2 is kept in the horizontal state without the vertical fluctuation, and thus a sensor 1 approaches the top part of a stack 7. In addition, since the arm 2 is fixed to the rotating shaft 12 in the shape of bar, the fluctuation in the horizontal direction is also hard to occur in the arm 2.

Title: High-speed voith-schneider propeller
Inventor: TANAKA HIROSEKI
IPC: B63H1/10
Filed: 1979-11-16
Abstract: PURPOSE: To use the Voith-Schneider propeller as a propeller for a high-speed boat by a method wherein the cross-sectional shape of the blades of the Voith-Schneider propeller generally used for a tugboat or the like is changed into a wedgelike shape.  
     CONSTITUTION: The cross-sectional shape of the blades 11 of the Voith-Schneider propeller is changed into a curbed wedgelike shape, and the base plate 12 of the propeller is fixed to a steering rod 14 through a supporting column 13. A peripheral edge part 15 is fitted to the bottom of ship 16 so that only an annular part 17 can be rotated together with the blades 11. When said propeller is equipped to a high- speed boat, it is possible to avoid the inconvenience that the inside and the back of the blades alternate with each other for every half revolution of the propeller, due to the substantial absence of contact between water and the blades because of the cavitation taking place at the entire back surfaces of the blades. In addition, since the bottom plate does not rotate with the blades, frictional resistance is reduced and the efficiency of propulsion can be enhanced.
