Title: Detection of level of molten metal
Inventor: NAGANUMA YOICHI
IPC: G01F23/26
Filed: 1989-09-19
Abstract: PURPOSE:To measure the level of a molten metal with high reliability by providing a transmitting coil and a receiving coil confronting to each other outside a container in which the molten metal is present, and monitoring an alternating voltage passing through the receiving coil. CONSTITUTION:A transmitting coil 4 and a receiving coil 7 are provided confronting to each other outside molds 2, 3 where a molten metal 1 is present. An alternating voltage of an alternating current source 5 is impressed to the transmitting coil 4. The generated alternating magnetic flux is allowed to pass through the molten metal 1. An alternating voltage induced in the receiving coil 7 by the passing magnetic flux is received. Harmful noise components are removed from outputs of the receiving coil 7 at a band pass filter 8, and thereafter, only signals synchronizing with the alternating current source 5 are converted to direct current voltage signals by a synchronous rectifier 9 and effective signals alone are taken out through a low pass filter 10. Accordingly, since the sensor is not inserted in the molten metal, the level can be measured with high reliability.

Title: Method for preventing rusting of sacrificial iron anode
Inventor: SAKANISHI AKIHIRO
IPC: C23F13/00
Filed: 1990-09-12
Abstract: PURPOSE:To prevent the rusting of a sacrificial iron anode with a film until the operation of a plant is started and to facilitate the removal of the film at the time of the operation by applying a water-soluble film forming corrosion inhibitor to the surface of the iron anode for cathodic protection of a heat exchanger and a condenser utilizing seawater fitted to the inside of a water chamber. CONSTITUTION:A sacrificial iron anode is fitted to the inside of a water chamber and a water-soluble film forming corrosion inhibitor contg. water-soluble vinyl resin and nitrite is applied to the anode. Since the surface of the anode is isolated from the open air contg. oxygen and moisture, the rusting of the anode can be prevented. Since the corrosion inhibitor is soluble in water, it is easily dissolved and removed when seawater is fed at the time of operating a plant and the function of the sacrificial anode is fulfilled.

Title: Filter system
Inventor: KOJIMA SHINRI
IPC: C02F1/44
Filed: 1986-10-13
Abstract: PURPOSE:To provide a filter system which withstands acids and org. solvents by covering the circumference of an ultrafilter (hereafter expressed as UF) module case with a protective cover formed of a material which withstands the acids and org. solvents. CONSTITUTION:Plural pieces of bundled UF module membranes 7 are housed into the UF module case 8 and pure water is passed into the UF module membranes 7. The pure water is filtered by the membranes 7 and the ultrapure water is obtd. The circumference of the UF module case 8 is coated with the protective cover 9 formed of the material which withstands the acids and org. solvents (e.g.,; 'Teflon(R)'). As a result, the direct exposure of the UF module case to the acids and org. solvents is prevented. Cracking of the UF module case is, therefore, obviated even if the filter system is exposed to the org. solvents and acids leaking from a clean room. The water leakage accident of the filter system is thereby prevented.

Title: Nonvolatile semiconductor memory
Inventor: MIYAGAWA TADASHI
IPC: G11C16/06
Filed: 1992-09-11
Abstract: PURPOSE:To shorten a writing time and to accelerate erasing at a high speed by applying a high voltage to a control gate of a memory cell, and simultaneously writing it by a tunnel current flowing from a channel region to a floating gate. CONSTITUTION:A predetermined drain voltage VD, a control gate voltage Vcc are applied to a row decoder RD and a cell(C) selected by a column gate CG. Then, hot electrons are generated in a high electric field near a drain, and simultaneously written by a tunnel current to be injected in a floating gate. In this case, an electric field is generated from a channel(Ch) to a gate (FG) near a source S. In the case of erasing, when all the bits are simultaneously written and the voltages VCC, VD are set to predetermined values, a tunnel current from the vicinity of the source is injected in the gate FG. Then, a drain current is reduced as compared with the case of ordinarily writing, and simultaneous writing is performed without wire disconnection due to an overcurrent. Thus, a writing time is shortened, and erasing can be accelerated at a high speed.

Title: Connector with slider
Inventor: FURUHIRA YOSHIHIKO
IPC: H01R12/24
Filed: 1995-08-29
Abstract: PROBLEM TO BE SOLVED: To prevent a dropping-out of a flexible conductor by protruding a temporary holding part for temporarily holding the flexible conductor inserted into a housing with the contact of a contact pin on a part of the housing inner surface. SOLUTION: A flexible conductor 3 inserted into a housing 1 in the state where a slider 4 is pulled out is temporarily held between a temporary holding part 6 and the contact 5 of a contact pin 2 so as not to be carelessly dropped out. Therefore, it is not required to operate the slider 4 by one hand while holding the flexible conductor 3 by the other hand, and the operation from the insertion of the flexible conductor 3 to the pushing and locking of the slider 4 can be performed by a single hand to facilitate the work. Since the flexible conductor 3 inserted into the housing 1 is temporarily held, the flexible 3 is never dropped out until the slider 4 is inserted. The troublesome work of reinserting the flexible conductor 3 is thus eliminated.

Title: Food container
Inventor: KUSHIDA HIDEO
IPC: B65D1/00
Filed: 1987-09-30
Abstract: PURPOSE:To obtain food containers heat-insulating and excellent in heat resistance, by laminating a non-foaming polypropylene resin layer containing a specified amount of inorganic filler in polypropylene resin at least on a surface of a foaming polypropylene resin layer. CONSTITUTION:A food container has a foaming polypropylene resin layer and a non-foaming polypropylene resin layer inside it. A non-foaming polypropylene resin layer containing 5-150wt. part of inorganic filler per 100wt. part of polypropylene resin is laminated at least on a surface of the foaming polypropylene resin layer. As the foaming agent forming the foaming polypropylene resin layer, the combinational system of sodium hydrogen carbonate and monosodium citrate is preferable. The compounding amount of the foaming agent is about 0.1-5wt. part per 100wt. part of polypropylene resin, and the foaming magnification is about 1.05-3.0 times. If the content of the inorganic filler to the non-foaming polypropylene resin layer is under 5wt. part, improvement in heat resistance of the food container is insufficient; if exceeding 150wt. part, manufacture of the container itself is difficult by molding.

Title: Bath device and detection for completion of drain of bath tub in bath device
Inventor: NOGUCHI YUKINOBU
IPC: F24H1/00
Filed: 1994-09-13
Abstract: PURPOSE: To efficiently clean a bath tub by estimating and calculating remaining water drain time from a reference water level to a set water level for drain completion upon start of draining the bath tub and informing of the drain rein completion when the drain time from the reference water level reaches the calculated time for draining the remaining water. CONSTITUTION: A water level lowering timer 32 detects a water level drop time from a water level upon start of draining a bath tub to a reference water level during drain of the bath tub. A drain timer 33 measures a lapse of time for draining after the water level of the bath tub is lowered to a reference water level. A calculating part 29 of remaining water drain time estimates and calculates the drain time of remaining water from the reference water level to a preset water level for drain completion, based on the information of drain state from a water level upon start of draining to the reference water level. A drain completion informing means 34 informs of the drain completion when the drain timer 33 completes to measure the drain time for remaining water.  Thus, even when a user is in a position remote from a bathroom he can grasp the correct time of drain completion of the bath tub and can clean the bathtub or the like at a good timing.
