Title: Rotary type opening/closing valve for internal combustion engine
Inventor: NONAKA AKIRA
IPC: F01L7/10
Filed: 1994-09-13
Abstract: PURPOSE: To raise the efficiency of an internal combustion engine and simplify the structure of the engine by fitting a rotary plate having cuts to a cylinder head in a freely rotatable manner and rotating it at a specific ratio to rotary speed of the internal combustion engine. CONSTITUTION: Cuts 2 in sector form, of size equivalent to eight divisions of a rotary plate 1, are formed in a rotary plate 1 in semispherical form, rotating with a shaft 3 as the center. A cut in a first sector portion is formed as an exhaust port 8 and a cut in a third sector portion as an intake port. A circular hole is formed in a sixed sector portion, an ignition plug 9 facing it. A regulating plate for adjusting the rotary plate 1 and the intake timing is fitted in a hollow in semispherical form within a cylinder head 6. The rotary plate 1 is rotated with power from a crank shaft, with a shaft as the center. In this case, rotational speed of the rotary plate 1 is so regulated that it rotates for one turn with four strokes of the internal combustion engine, i.e., intake, compression, explosion and exhaust.  Accordingly, the intake/exhaust structure of the internal combustion engine is simplified and also the efficiency of the internal combustion engine is raised.

Abstract: PURPOSE:To stably operate a motor at switching time by increasing within a low voltage until switched to a signal from rotating magnetic field generating means and a signal of comparator group from starting time, detecting the rotation and generating a switching command signal. CONSTITUTION:A brushless motor 3 having a magnet rotor 5 is rotated by controlling the energization of an armature winding 4 by semiconductor switching group 2.

Title: Sense amplifier circuit
Inventor: NOGAMI KAZUTAKA
IPC: H01L29/78
Filed: 1985-11-15
Abstract: PURPOSE:To prevent a sense amplifier sensitivity from decreasing or erroneously operating due to the irregularity in transistor characteristics by equalizing the directions of a source and a drain. CONSTITUTION:A sense amplifier is composed of a transistor Q1 which uses a source as sense amplifier activation signals 1c, 4c, a gate as bit lines BL', 2b and a drain as bit lines BL, 1a, 4a, and a transistor Q2 which uses a source as sense amplifier activation signals 1c, 4c, a gate as bit lines BL, 2a, and a drain as bit line BL', 1b, 4b. That is, the direction 4c to 4a of the source S and the drain D of the transistor Q1 and the direction 4c to 4b of the source S and the drain D of the transistor Q2 are equalized by replacing the dispositions of the bit lines BL and BL' between the transistors Q1 and Q2. When the directions are equalized in this manner, the conditions at ion implanting time become the same between the transistors Q1 and Q1, transistor characteristics become equal. Thus, the sense amplifiers are balanced to perform as the sensitivity of the designed value.
