Title: Electric hot-water device for space heating
Inventor: SUGIYAMA TAIZO
IPC: F24D3/00
Filed: 1990-11-26
Abstract: PURPOSE:To use an electric hot-water device as a floor heater, a 'kotatsu' heater, a heat-keep apparatus and a dryer by installing the lateral type electric hot-water device under the floor and utilizing heat radiated from the electric hot-water device. CONSTITUTION:The side faces, both the sides and the lower face of an electric hot-water device 1 are covered with a heat insulating material 2 and fixed onto outer frames 3. For example, the upper surface material of a floor heater consists of a floor material and a heat accumulating material, and the upper part of the electric hot-water device 1 installed under the floor is covered with the upper surface material. Thereby, the amount of heat radiated from the electric hot-water device 1 is received by the heat accumulating material and transmitted to the floor material to warm it. By this method, the device can be used for heating the floor.

Title: Production of liquid crystal display device
Inventor: KAIZE YASUYOSHI
IPC: G02F1/1339
Filed: 1991-12-05
Abstract: PURPOSE:To attain a uniform thickness and to form a uniform oriented film even around the protrusion of a spacer by forming the spacer of resin on a substrate and then forming the oriented film by vacuum-deposition polymerization. CONSTITUTION:A spacer 35 of resin or a spacer 35 fixed by resin is formed on a substrate 30, and then an oriented film 32 is formed by vacuum-deposition polymerization. In the polymerization, the raw monomer of polyimide is vaporized to form a polyamic acid film on the surface of the substrate 30 on the electrode side, and then the polyamic acid is polymerized to a polyimide. The raw monomer is vaporized in vacuum to prevent a collision between the vaporized monomers, hence the monomer vapor is directly deposited on the electrode substrate, and a uniform polyamic acid film is formed. Polystyrene, silica, acryl, nylon, etc., are exemplified as the resin composition to be used for the spacer 35.

Title: Data communication system
Inventor: NAGATOMO AKIHIKO
IPC: H04L12/46
Filed: 1999-11-12
Abstract: PROBLEM TO BE SOLVED: To prevent the existence of a non-storage area where communication data is not stored and to substantially use storage capacity which is set since a storage area is divided into prescribed sizes (allocation areas) which are previously fixed and the size of communication data to be stored is not considered in a memory in a conventional data communication system. SOLUTION: In a data communication system, a head address indicating the position of communication data written into a memory part in a storage area is written in a register which is FIFO-controlled, a table for suggesting that communication can be kept and new communication data can be written is generated and a control part manages them. Thus, an allocation area obtained by fixedly dividing the storage area of the memory part is discarded, the storage area is integrally managed and the occurrence of a data non-storage area is prevented.

Title: Method for measuring concentration of additive in electrolyte, and method for controlling concentration of additive
Inventor: OKAMOTO HIDENORI
IPC: C25C7/06
Filed: 1994-12-26
Abstract: PURPOSE: To simply measure the concentration of an additive in an electrolyte by an inexpensive facility in a maintenance-free way by measuring the change with time of the voltage of an electrolytic cell based on the relation between the concentration of the additive and the voltage of the electrolytic cell. CONSTITUTION: The change with time of the voltage of an electrolytic cell is used so as to determine the concentration of an additive, e.g. glue. Since the concentration of the glue and a rising speed of the voltage of the electrolytic cell hold a linear correlation, a straight line nearly passing an origin is obtained when the relation is plotted in X, Y directions. A predetermined amount of glue solution is added to a solution to be measured, and a working curve of a concentration (X) of the added glue and a rising speed (Y) of the voltage of the electrolytic cell is formed. Thereafter, the working curve is extrapolated to a point where the rising speed is 0 (Y=0), and an intersection with the X axis is obtained. The concentration of the glue at the intersection indicates the concentration of the glue in the electrolyte to be measured.  The concentration of the glue can be thus determined. The working curve is formed for every solution to be measured, and therefore, the concentration of the glue can be simply and correctly measured without being influenced by the change of the composition of the electrolyte.

Title: Tape tension detector
Inventor: MITSUYASU TAMOTSU
IPC: G11B15/093
Filed: 1993-12-21
Abstract: PURPOSE:To detect tape tension with good responsiveness from an ordinary fixed post and a rotary roller which are not attended with positional changes. CONSTITUTION:The fixed post 9 and a supporting shaft 10 of the rotary roller are fitted with a vibration generator 11 and a vibration receiver 12, and a change in a specified resonance frequency is measured by the vibration receiver from a rectangular wave signal given to the vibration generator as an electric signal, white noise or a signal for sweeping the vicinity of the resonance frequency, and tape tension is detected to be estimated from this measuring result, thus detecting the tape tension with good responsiveness without using a tension arm. By using this value, a high speed tension servo can be operated on a tape feed reel. By this constitution, since the detector device itself is so small as not to occupy much space, the tension detection can be carried out in the vicinity of a drum where an accurate tape tension value is requested in a VTR, and an ideal tension servo can be constituted.

Title: Power supply
Inventor: MATSUMAE HIROSHI
IPC: H02M3/155
Filed: 1989-12-14
Abstract: PURPOSE:To suppress an inrush current at the time of switching on power supply and besides to suppress the deterioration of efficiency by an inrush- current-suppressing circuit which suppresses inrush currents, by increasing the current value flowing in a smoothing capacitor, by the increase of charging voltage of a timing capacitor. CONSTITUTION:After a key switch 5 is made, a timing capacitor 10 is charged through the first resistor 11. With the rise of the charging voltage of the timing capacitor 10, the voltage between the gate and source of a FET 9 rises and the on-resistance value becomes smaller. As the result of this, the drain current of the FET 9 increases and a current quantity supplied to a smoothing capacitor 6 increases. And after the voltage of the capacitor 6 has risen up to the voltage of a power source 4, a steady-state current determined by a load 2 flows through the FET 9. This suppresses an inrush current into the smoothing capacitor when the switch 5 is turned on.
