Title: Manufacture of thin film transistor
Inventor: EMOTO FUMIAKI
IPC: H01L29/78
Filed: 1989-06-16
Abstract: PURPOSE:To form a source/drain region with a small amount of ion implantation by carrying out ion implantation by changing an ion implantation angle to restrain ion channeling. CONSTITUTION:A polysilicon film is deposited by using a low pressure CVD method to a quartz substrate 3. An amorphous silicon 4 which is formed by implantation of silicon ion 1 to a polysilicon film is patterned to an island and annealed by an electric furnace for recrystallization. And, the polysilicon film 4 of a large grain diameter is formed on the quartz substrate. Then, a gate oxide film 7 and a polysilicon gate electrode 6 are formed on the polysilicon film 4, and a source/drain region is formed through phosphorus ion implantation. Ion is implanted to the silicon at an implantation angle apart by 5 deg. or more from an ion channeling direction. Thereby, a source/drain region can be formed with a small amount of ion implantation.

Title: Semiconductor device
Inventor: YOSHIMURA EMI
IPC: G11C17/08
Filed: 1989-06-16
Abstract: PURPOSE:To control polarity switching by turning on a state between a power supply and an output by depressed ion implantation, turning off a state between earth and the output, or turning off the state between the power supply and the output and turning on the state between the earth and the output. CONSTITUTION:As depressed ion implantation is performed only for transistors Q1, Q2, the transistors Q1, Q2 are turned on, and Q2, Q1 are off, so that corresponding potentials at a node N1 are H, L levels and potentials an N2 are L, H levels. Herein, once a signal IN1 is inputted into a node N3, a transistor Q6 is turned on when ion implantation is conducted only for the transistor Q1, and hence a signal OUT1 of the same phase as that of the signal IN1 is issued from a node N4. Reversely, when the ion implantation is conducted only for the transistor Q2, a transistor Q5 is turned on and the signal OUT1 becomes a signal reverse to the signal IN1 in phase. Hereby, a two polarity output signal can be yielded from one signal by controlling depressed ion implantation.

Title: Rotor of prime mover utilizing gravity
Inventor: MORI MASUMI
IPC: H02K53/00
Filed: 1996-05-27
Abstract: PROBLEM TO BE SOLVED: To simplify construction and eliminate the noise caused by a rotating part or a sliding part, by a method in which a weight element to which a permanent magnet is fixed is attached to a rotary shaft. SOLUTION: A semi-circular or fan-shaped weight element 2 to which a magnet 1 is fixed is attached to a center shaft 3 to form a rotor. If the position of the rotor is shifted from an uppermost position even only a little, the rotating force is produced by utilizing the gravity and the rotor is turned to a lowermost position and continues rotation to some extent by the inertia. Before the rotating force by the inertia is extinguished, the rotating force is maintained by the influence of the interrelation between the magnet 1 and a stator side magnet 4 having a trench. By switching the polarity of an electromagnet 5 which is provided on the end of the stator side magnet 4, the action of escape and repulsion from the magnetic field of the stator side magnet 4 is applied to the magnet 1 to repeat the rotation.  With this constitution, the construction can be simplified and, as a sliding arm and a cam mechanism are eliminated, almost no noise is produced.
