Title: Driving method for fet
Inventor: OOTA KAZUNARI
IPC: H01L21/338
Filed: 1983-08-10
Abstract: PURPOSE:To enable to obtain the excellent characteristic of noise index by a method wherein a channel current is controlled by impressing a voltage between the conductive semiconductor substrate of the FET and the source electrode. CONSTITUTION:An N type GaAs active layer 12 is mounted on the N<+> GaAs semiconductor substrate 10 via I type GaAs buffer layer 11, resulting in the construction of an FET. In opposition to a source electrode 13, a positive voltage is impressed on a drain electrode 14, a negative one on a gate electrode 15 and further a negative one on a substrate ohmic electrode 16. As a result, a depletion layer 17 expands as shown in the figure, and then can independently control the drain-source current by variation in the voltage impressed on the electrode 15 and the electrode 16. Since the unstable region 18 at the interface enters in the depletion layer 17, the improvement of the characteristic of NF (noise index) can be contrived.

Title: Power failure detector
Inventor: MIYAHARA KOUICHI
IPC: G06F12/16
Filed: 1981-09-18
Abstract: PURPOSE:To prevent the malfunction of a device such as a measuring instrument, by writing prescribed data for power failure detection in a prescribed area of a semiconductor memory to be backed-up and reading out this data by a CPU to detect the power failure when power is turned on. CONSTITUTION:If the user of the device turns off a switch SW2 when he turns off a power source 4, an interlocking switch SW1 is turned off.

Abstract: PURPOSE: To eliminate a disadvantage of a player, that a player is obliged to adjust a shooting force by a method wherein when a ball is shot aiming at a pattern start gate, the game ball which has passed the pattern start gate is introduced to a start prize port, and while a right is being generated, a second variation prize device generates a possibility wherein the player is placed under an advantageous state by the game ball, for the constitution of a pachinko machine. CONSTITUTION: When a game ball passes a pattern start gate 7, a pattern display unit changes the display of a pattern. Then, while a right is being generated, the game ball Y which has passed the pattern start gate 7 is introduced to a discharge port 39 through a guide passage 38, and stays at a start port 27 of a start prize device 4. Then, the game ball enters a holding unit by the rotation of a rotating body, and discharged to the outside of the machine, and at the same time, prize balls are released. This right ceases to exist when a game ball passes a special device operating area 12 or a specified number of game balls enter the start prize port. Until that state, a player can simply shoot game balls aiming at the pattern start rate 7, and the aiming particularly to the right side becomes unnecessary.
