Title: Constant current circuit varying output
Inventor: NAMIKI MASAYUKI
IPC: H03F3/347
Filed: 1983-07-01
Abstract: PURPOSE:To set up an output current value to a required voltage value accurately by connecting a float gate of an unvolatile memory to at least one of IGFETs constituting a constant voltage circuit and writing charge in the float gate. CONSTITUTION:When -1V is applied to an N<+> injector 18 through an injector terminal, forward current is flowed and electrons are injected from the injector 18 to a P<-> substrate 16. A part of the electrons is flowed from the substrate 16 to an N<-> substrate 15 as a base current and the most of them is flowed to a control gate 17 as a collector current. In this case, the voltage applied to the control gate 17 is coupled at its capacity and also applied to the float gate and an inversion layer is formed on the surface of the substrate under the float gate. Consequently, the charge injected from the injector terminal 25 is accelerated and a part of charge jumps the wall of the potential of a thin insulating film 24 and enters the float gate 23. When the charge is written in the float gate 23, the threshold is raised and an electric field is not almost applied to the insulating film 24, so that the output current value can be matched to the required voltage value.

Title: Memory cartridge
Inventor: NISHI SEIKI
IPC: G06K19/00
Filed: 1987-05-19
Abstract: PURPOSE:To prevent a battery from being consumed when a memory is not used and to prevent a power source from being turned off arbitrarily by a user, by providing a movable needle inside the end section of a memory cartridge and causing the needle to be pushed and to turn on a switch when the cartridge is loaded in an electronic equipment. CONSTITUTION:A movable body 7 is put in a fitting hole 6 at the end face of a memory cartridge 1 and, when the cartridge 1 is loaded in the electronic equipment, the movable body 7 is pushed into the hole 6 by means of the push pin 12 of the equipment and a getting-off preventing section 7b passes through a supporting body 8. Another supporting body 8 on the left side works as the fixed contacts A and B of a switching device and the traveling contact C of the needle 7 is brought into contact with the contacts A and B as the needle gets into the hole 6. Thus electric power is supplied to a semiconductor memory 3. Therefore, the switch is turned on only when the memory 3 is loaded in the equipment and the consumption of the battery can be prevented while the memory is not used. Moreover, since the needle cannot be pulled out when the needle is once pushed into the hole, unprepared disconnection of the power supply to the memory can be prevented.

Title: Washing machine
Inventor: ANDO MASARU
IPC: D06F39/08
Filed: 1992-05-13
Abstract: PURPOSE:To prevent water from pooling in a storage casing by agitating water with the use of a preagitating means after supply of water, and by replenishing a washing machine with water, as necessary. CONSTITUTION:A level sensor 13 detects the level of water in a water tank 2 so that the supply of water is stopped when the level of water comes to a predetermined level. Thereafter, a pulsator 5 is rotated so as to allow garments to absorb water. Accordingly, the garments are impregnated with water so that the level of water lowers. The level of water at this time is detected by the level sensor 13 so as to determine whether the level of water is lower than the set level or not. That is, a comparing means 29 compares a decrease in the water quantity with a supply quantity which is required for causing a siphoning phenomenon within the storage easing 14. Further, when the decrease in the water quantity is larger than the supply water quantity required for the siphoning phenomenon, a water replenishing means 30 replenishes the water tank 2 with water until the level of water comes to the predetermined one, but when the decrease in the water quantity is smaller than the supply water quantity for the siphoning phenomenon, a replenishment stopping means stops the replenishment of water.

Title: Airflow direction change-over device for air conditioner
Inventor: OKABE IKUAKI
IPC: F24F13/14
Filed: 1982-07-14
Abstract: PURPOSE:To enable to prevent dewing from occurring in a cooling operation, by a method wherein a gap constituting an air passage is provided between a lower surface of a blow-off port and an end part of an airflow direction plate when the plate is in a horizontal position. CONSTITUTION:A rotary shaft 10 is provided as one body with the airflow direction plate 9 (which has a surface shape conforming to that of an ornamental cover 3) in front of both side surface end parts of the plate 9, and is located at such a position that a gap constituting an air passage is formed between the lower surface 3b of the blow-off port and an end part of the plate 9 when the plate 9 is in the horizontal position. Accordingly, since the rotary shaft 10 is located on the side surface of the plate 9, an operational distance is short, which leads to favorable operability. In addition, since cool air blow off flows so as to envelop the plate 9 as indicated by large arrows when the plate 9 is maintained in the horizontal position as indicated by a dotted line in the cooling operation, dewing does not occur on the plate 9 even though the plate 9 is cooled, since warm air does not touch the plate 9 but flows as indicated by an arrow F.

Title: Method for purifying hydrogen gas
Inventor: NAKADA YASUSHI
IPC: C01B3/56
Filed: 1984-06-12
Abstract: PURPOSE:To prevent the deterioration of a metal hydride in purifying hydrogen gas by injecting crude hydrogen gas into a vessel filled with the metal hydride to occlude the hydrogen in the metal hydride, decompressing the vessel to expel impurity gases remaining in the vessel, by decompressing the interior of the vessel previously to a specific pressure. CONSTITUTION:A metal hydride (MH1) is filled in the first vessel 1, and crude hydrogen gas containing impurity gases is introduced from a gas cylinder 7 thereinto under pressure to occlude the hydrogen in the metal hydride (MH1). A valve 9 of a purge pipe 8 is then opened to expel the residual impurity gases in the vessel 1, and a valve 10 is opened to decompress the interior of the vessel 1. Hydrogen gas of high purity is released from the metal hydride (MH1) in the vessel and fed to a system 13 for using the purified hydrogen gas. In this case, the vessel is connected to a vessel 14 filled with a metal hydride (MH2) having a lower hydrogen occlusion pressure than the hydrogen release pressure in the alpha-phase region of the metal hydride (MH1) through a pipe 17 to occlude the hydrogen occluded in the metal hydride (MH1) in the metal hydride (MH2). Crude hydrogen gas is then injected into the vessel 1 to prevent the deterioration of the performance due to the repeated use of the metal hydride (MH1).
