Abstract: PURPOSE:To reduce a variation quantity of the saturation current between a source and drain, by forming a gate electrode made of aluminium, and then laminating an insulation film on the whole surface of a compound semiconductor substrate including the gate electrode, and thereafter performing a heat treatment at a predetermined temperature, and thereafter forming a source and drain electrode. CONSTITUTION:Al is deposited using a depositing apparatus of electron beam type, and a lift-off is prformed using an organic solvent, and a gate electrode 7 is obtained. Then, using a PCVD method, an SiN film 8 is formed on the whole surface of a wafer, and in this state, using a heater 22 of an electric furnace 20, the heat treatment of 400 deg.C, 30 minutes is performed in the H2 atmosphere of 1l/minute in flow rate. Thereafter, using a conventional photoetching and alloying method, a source electrode 9 and a drain electrode 10 are formed. In this manner, in an AlGaAs/GaAs HEMT having an Al gate, after the Al gate electrode 7 is formed, the heat treatment at 400-500 deg.C is performed. Thereby, the phenomenon peculiar to the AN gate of a drain saturation current varying can be reduced to about one-tenth.

For example, 300pts.wt. of water is mixed with 300pts.wt. of an adhesive based on vinyl acetate emulsion resin, 5pts.wt. of alum, and 1pt.wt. of salt. A cut plant such as cut flower, cut grass, cut tree, etc. is hung upside-down and sprayed with the mist of the preservation liquid e.g. from a spraying nozzle, and dried. The spraying and drying processes are repeated several time to obtain a dry plant having lively appearance and firm shape. The plant can be put in a vessel such as a vase or a basket, or the flower or leaf of the plant can be used as an accesory such as a breast pin. It is also possible to make a potted plant to a dry plant as it is. A cut plant can be stored in the living state in a closed vessel by the use of the preservation liquid.

Title: Supersonic wave humidifier
Inventor: KOBAYASHI SHIGEHITO
IPC: F24F6/12
Filed: 1984-07-26
Abstract: PURPOSE:To make a cost-down of the product under a reduction of cost of component elements and a decreasing of steps of work as well as eliminating a tipping switch by a method wherein a float switch is provided with a function for stopping an operation of an oscillating element even in case of overturning of the device. CONSTITUTION:A resilient member 129 always biases a float 112 toward a bottom surface 130 in a water accumulation part under a recovering force. However, a buoyancy of the float 112 at a specified water level surface 114 is set sufficiently higher than a recovering force of the resilient force of the resilient member 129, and the specified water level 114 of the float 112 is restricted by a stopper 131 or the like. When the water feeding tank 102 lacks water and the water level of the water storing part 104 starts to descend, the float 112 is also started to descend under an influence of the recovering force of the resilient member and a gravity, the reed switch 115 is turned OFF at the position of 112B and then an operation of the vibrating element 105 is stopped. In turn, in case that the main body is fallen over a flat surface and the water in the water storing part 104 is flowed out, the float 112 is moved toward the bottom surface 133 of the water storing part 104 only with the recovering force of the resilient member and then the reed switch 115 is turned OFF and the driving operation of the vibrating element 105 is terminated.

Title: Read control system of rotary memory
Inventor: UDA MORIHIKO
IPC: G11B20/18
Filed: 1983-08-30
Abstract: PURPOSE:To improve the success factor of the reread trial when a read error is produced by using a means which saves and holds a data address and the remaining byte count every time a record is read out normally when a read instruction is executed. CONSTITUTION:The data of a rotary magnetic memory 40 are stored in the form of a gathering of records R1-RN consisting of data D1-DN and check codes C1-CN. The instruction codes read out of a main memory 1 are set to a register 12 of a channel device 10 as well as to a register 21 of a controller 20. Thus the transfer of data is controlled between the memory 40 and the memory 1. When a read checking circuit 23 detects the normal read, a control circuit 22 saves the data address and the remaining byte count to save registers 15 and 19. When the circuit 23 detects an error, the circuit 22 is positioned again at an immediately preceding positioning enable point and at the same time starts the transfer of data based on the data address and the remaining byte count held at registers 15 and 19. Thus, the success factor of the reread trial is improved.
