Patent JP-H0439942-A (JP)
Title: Semiconductor device and manufacture thereof
Inventor: AWANO YUJI
IPC: H01L29/812
Filed: 1990-06-05
Abstract: PURPOSE:To suppress a short-channel effect, to sufficiently reduce a parasitic resistance while the deterioration of a gate breaksown strength is being prevented and to enhance a high-speed switching operation and a high-frequency response ability by a method wherein a low-resistance layer whose concentration is higher than that of and whose resistance is lower than that of a channel layer is formed. CONSTITUTION:An i-AlGaAs layer 14 used to suppress a substrate electric current is formed on a semiinsulating GaAs substrate 1. Then, an n<+> GaAs layer 12 whose film thickness (100 to 200Angstrom ) is the same as or lower than that of a two-dimensional electron gas layer 10, which comes into contact with both sides of the twodimensional electron gas layer 10 and whose concentration is higher than that of the two-dimensional electron gas layer 10 is formed. Thereby, the region of the layer 10 can be narrowed and a parasitic resistance component Rs can be reduced. Since the layer 14 is formed, the substrate electric current can be reduced. A gate electrode 4 is formed on an n-AlGaAs layer 8. Since the electrode 4 does not come into contact with the n<+> layer, the deterioration of a gate breakdown strength can be prevented. The aspect ratio Lg/d of a channel is not changed as compared with that of conventional cases. As a result, it is possible to prevent the deterioration by a short-channel effect and to enhance a high-frequency response ability.

Title: Heating and cooking device
Inventor: TANAKA MASAMI
IPC: F24C1/00
Filed: 1989-06-09
Abstract: PURPOSE:To enable a food to be rotated while being held in an air and to prevent the food from being crashed when the food is turned over by a method wherein a food holding member supporting means for supporting a food holding member within a housing and a driving means for driving the food holding member supporting means are provided. CONSTITUTION:An accessory rod 30 is thrust into a fish to be cooked, one side surface of the fish is faced upward, both ends of the rod 30 are set in rod supporting means 40a and 40b and then a heating time is set in response to a size of the fish. As time of about 60% of a full heating time from a starting of heating elapses, a control relay 51 of a driving means 50 is turned ON and then a fish being heated within the housing is reversed. With such an operation, a surface of the fish to be burned is automatically changed within the housing and a user is released form her turning over operation. Since the fish is held in the air during entire heating time, there is no possibility that a skin of the fish is peeled off during turning-over operation or a fish meat is not crashed.

Title: Method for inhibiting corrosion
Inventor: AKASHI SUMIO
IPC: C23F11/04
Filed: 1983-08-10
Abstract: PURPOSE:To inhibit the corrosion of ferrous metal due to the sticking of an acidic aqueous soln. by adding oil to the aqueous soln. which is used to pickle ferrous metal or is spread as agricultural chemicals or the like and by emulsifying the oil with a surfactant. CONSTITUTION:One or more among mineral oil, vegetable oil and a water insoluble liq. polymer are added to an acidic aqueous soln. of an inorg. or org. acid, and they are emulsified with an anionic or nonionic surfactant. The acidic aqueous soln. is used to pickle ferrous metal or to wash chemically a chemical plant, or it is spread as agricultural chemicals. When the resulting liq. sticks to ferrous metal, it is possible to consider that a hydrophobic oil film coats the metallic surface by adsorption, isolates the external atmosphere, and prevents the formation of rust. Accordingly, the corrosion of ferrous metal in various environments can be reduced independently of time elapsed until neutralization is caried out after acid treatment. Rust is smoothly removed during immersion.

Title: Facsimile device
Inventor: KATSURAGI SHIGERU
IPC: H04N1/23
Filed: 1982-08-27
Abstract: PURPOSE:To prevent the deterioration in picture quality, by making the timing of coloring of a heat sensing recording chart constant at all times, in a facsimile device provided with a heat sensing recorder. CONSTITUTION:When a signal is transferred serially to a shift register with a CLOCK and the parallel transfer is finished, a parallel transfer end signal is generated, and a pulse width cut timer 10 and a maximum time timer 11 are turned on. Since a counter 12 is cleared in this case, a decoder 13 selects a BLK1, and a pulse having a pulse width until the maximum time timer 11 turns off is applied with the pulse width cut timer 10. When the maximum time timer 11 is turned off, the counter 12 is advanced by one and a BLK2 is generated. Since a prescribed timing pulse is obtained in this way, even if the pulse width applied to a head is changed, the timing of heating of the heat sensing recording chart is made constant at all times.

Filed: 1979-11-19
Abstract: PURPOSE:To restore the rise of data line level caused automatically by bump noise and so on and prevent the delay of access time by attaching high resistance mechanism which flows reak current between the data line from EPROM and the earthing terminal. CONSTITUTION:MISFETQ5 and Q6 which apply constant voltage to the gate of MISFETQ4 are attached so that constant current MISFETQ4 is applied between data line D and the earthing potential terminal and connected to them in series and a common gate is connected to their connecting points. When the level of data line D is rised by bump noise and so on, the level of data line D is dropped by the action of constant current and automatically restored to the steady state because the reak current circuit caused by constant current MISFETQ4 is attached to data line D. Thus, the delay of access time caused by bump noise and so on can be prevented.
