Title: One-side hot dipping method
Inventor: SATOU YOKICHI
IPC: C23C2/00
Filed: 1978-04-06
Abstract: PURPOSE:To prevent formation of undipped parts and adhesion of molten metal to a side not to be dipped in one-side hot dipping of a strip steel sheet by contact to hot dipping metal, by setting baffle plates in a metal bath to prevent swelling of the bath surface at a position where the sheet contacts to or approaches the surface. CONSTITUTION:Strip steel sheet 1 heated and activated in a reducing atmosphere is carried in hot dipping apparatus 2 kept under a nonoxidizing atmosphere, and it is moved horizontally with roll 6. Sheet 1 runs near the surface of hot dipping metal bath 3 contacts to a part of the bath surface raised with ultrasonic tips 4 to be one- side hot dipped. The dipped sheet is then turned upward with roll 7 and separated from the bath surface. Molten metal heated in channels 10 in frequency induction units 9 connected to metal bath vessel 8 circulates in low the directions of the  arrows to stir bath 3 and regulate it to a predetermined temp. Swelling due to the  circulation is prevented with baffle plates 11.

Title: Production of pure iron powder by hydrogen reduction of ferrous chloride crystal
Inventor: TOBA YUUKICHI
IPC: B01J8/12
Filed: 1979-04-04
Abstract: PURPOSE: To reduce the consumption of hydrogen and hydrochloric acid and enable pure iron powder to be continuously obtained at low temperature with high efficiency by using the reaction furnace composed of an upper stage reducing chamber and a lower stage cleaning chamber and suspension-cleaning the reduced iron particles by high-temperature hydrogen.  
     CONSTITUTION: The anhydrous fine particles of raw material ferrous chloride crystals are supplied into the upper stage reducing chamber 1 of the reaction furnace and are flowed by the high-temperature hydrogen flowing upward from the circumference of a partition 4, whereby they are reduced. The reduced iron particles are dropped into the cleaning chamber 7 of the lower stage by the operation of a sliding box 5, whereby they are suspended and swirled by the high-temperature hydrogen supplied from below. As a result of this, the hydrogen chloride gas mixed in the reduced iron particles is separated. The separated hydrogen chloride gas and hydrogen are temperature-controlled and are supplied to the bottom of the reducing chamber 1 of the upper stage. The reduced iron particles are fed from a take-out port 10 to a cooler 12. The reduction excess hydrogen and mixed hydrogen chloride gas in the reducing chamber 1 are taken out and recovered through an outlet 6.

Title: Food container and lid
Inventor: HASEGAWA TSUGUO
IPC: C08J9/04
Filed: 1996-02-27
Abstract: PROBLEM TO BE SOLVED: To obtain heat-insulating property wherein no ambustion is suffered even if hot water is discharged by molding a multi-layered sheet having two layers of a non-foaming layer and a foaming layer so that the non-foaming layer is located on an internal face. SOLUTION: A multi-layered sheet having two layers comprising at least a non-foaming layer and a 1.2 to 3.0 times foaming layer is molded so that the non-foaming layer is located on an internal face, thereby receiving a liquid- like substance heated to a range from 40 deg.C to a boiling temperature. Although a resin foaming ratio in a range of 1.2 to 3.0 times is effective, an especially preferable range is 1.4 to 3.0 times. The lower the foaming ratio the less heat insulation, while the higher the foaming ratio the more heat insulation improves, although shaping property and deep-drawing property at the time of molding is deteriorated, and curling suitability also tends to decrease. Thus, the liquid- like substance or a vaporized part at a high temperature may not penetrate through a lid material, so that this can be used as a lid material or the like for discharging hot water.

Title: Memory dial device
Inventor: TAKASHIMA SHOICHI
IPC: H04Q3/58
Filed: 1991-03-06
Abstract: PURPOSE:To enhance operability than that of a normal telephone by reading a memorized dial number without waiting the lowering of a start key when a memory dial key is lowered in a memory dial device so as to transmit a dial signal. CONSTITUTION:First, CPU judges whether a line wire butten 404 is lowered or not and judges whether it is an ISDN line or not at the time of lowering. In the case of ISDN, a dial numerical input by a ten-key 403 is waited. CPU confirms inputted numbers so as to store them in a memory and permits a display part 402 to display at every beam. Next, when the start butten is lowered, CPU starts a timer, informs ISDN of call setting and waits response from a party. CPU detects the lowering of a re-dial butten 405 so as to read the number stored in the memory and informs call setting when there is no dial input so as to be time-up. When an abbreviated dial is inputted from the ten-key, CPU ignores reception from the first beam and executes call setting by reading the dial number from the memory.

Filed: 1984-03-05
Abstract: PURPOSE:To detect faults of peripheral circuits not only of a memory element by using the numerical value of each address of a memory as the data on each address for checking. CONSTITUTION:When a memory address (x) is designated by an address generator 11, the address information is turned into a data input of a memory 14. The value of the data input is set at (x). At the same time, the address information is turned into an address input of the memory 14 and the value of this data is set at (x). Therefore the data (x) is written to the address (x). Here a distributor 13 has a fault and the address (x) is turned into (t). In such a case, the data (x) is written to the memory address (t). Then the read data is turned into (x) when the contents of the address (t) are read out by a memory read signal (n). Then the read data (x) is supplied to a comparator 15. Furthermore the address information (t) is also supplied to the comparator 15 and therefore the data (x) is compared with the information (t). Thus an error signal (p) is obtained.

Filed: 1988-02-25
Abstract: PURPOSE:To grasp a current variation in a state of a latent image charge is gradually neutralized by providing a capacitor having a capacitance corresponding to a photosensitive body between an ammeter and a measuring electrode. CONSTITUTION:A capacitor 4 having a capacitance corresponding to a photosensitive body is provided in a measuring circuit, and also, this capacitor 4 is saturated in advance by a voltage corresponding to the surface potential of the photosensitive body, and set so that a potential difference of both pole plates of the capacitor 4 becomes a potential difference between a measuring electrode 3 and a sleeve 1. That is, by this potential difference, discharge is executed from the capacitor 4, a developing current flows between the measuring electrode 3 and the sleeve 1, and it decreases in accordance with a storage charge quantity of the capacitor 4. Also, since a capacitance of the capacitor 4 corresponds to the photosensitive body, the state of decreasing the developing current corresponds to a state that charge of an electrostatic latent image is gradually neutralized at the time of actual developing. In such a way, a state that a latent image charge is neutralized can be measured.

Filed: 1985-03-04
Abstract: PURPOSE:To obtain a uniform magnetic film by setting a target face vertically to the direction where the angle formed by the face of a substrate and a face sloping to the substrate face is divided approximately into two equal angles. CONSTITUTION:The 1st magnetic film 2 having a gap face 4 is formed on a substrate 1, and a gap material face 5 is formed on the entire area of the substrate 1. Then the 2nd magnetic film 3 is formed. In this case, the face of the substrate 1 is tilted by a fixed angle beta to the face of a target 6. Then the face of the target 6 is set vertically to the direction where the angle phiformed between the face of the substrate 1 and the face 4 is divided approximately into two equal angles. Thus the entire face of the film 5 has approximately equal angle to the face of the target 6 at about 50 deg.. Thus the target 6 can be viewed at a sufficiently wide angle. Therefore the film forming direction is equal over the entire face of the film 5 and a magnetic film is formed at an equal speed.
