Patent JP-S5196662-A (JP)
IPC: H05B3/34
Filed: 1976-01-13
Abstract: An electric blanket shell is composed of first and second-needled textile fabrics with a yarn layer disposed in at least one of the needled fabrics. The yarn layer has a plurality of first planar yarns extending generally in a first planar direction. A heat-fusible component is disposed in at least one of the needled fabrics. A plurality of small, discrete sonically or ultra-sonically-produced fusion bonds, spaced from each other, link the needled fabrics to form a blanket shell. The fusion bonds form a series of patterns across a planar dimension of the blanket shell and the patterns define a series of channels, for receiving heating wires, between the needled fabrics. The patterns of fusion bonds are disposed in a direction transverse to the direction of the first planar yarns. The fusion bonds of any one pattern do not engage more than about 50% of the first planar yarns and overlaps of fusion-bond patterns are substantially avoided.

Title: Electric rice cooker
Inventor: TANAKA MASAO
IPC: A47J27/00
Filed: 1997-01-10
Abstract: PROBLEM TO BE SOLVED: To prevent steam from dispersing in the atmosphere by laying a steam passage for communicating an inner pot removably housed in a housing case to a water vessel laid at one side of a frame, introducing steam generated in the inner pot to the water vessel through the steam passage and then liquefying the steam via the contact of water. SOLUTION: When an inner pot 9 is heated via a heating plate 6 at the time of cooking rice, both of water and rice are heated to a high temperature level, and the inner pot 9 is gradually filled with steam. When the internal pressure of the inner pot 9 is below the preset pressure level, however, a ball 28 does not move and no steam is released. When a cooking process develops and the internal pressure of the inner pot 9 rises to the preset level, the ball 28 moves and the pressurized steam in the inner pot 9 flows into an introduction pipe 25. Thereafter, the pressurized steam enters one chamber 15 of a water container 13 from the introduction pipe 25 via a guide pipe 19, and changes to bubbles through a net material 18. Then, the bubbles rise from another chamber 16 of the vessel 13 in contact with water.  In this case, high temperature steam is cooled and liquefied with water, and stagnates in the chamber 16.

Title: Event control system
Inventor: MIYAZAWA TAKAYUKI
IPC: G06F9/46
Filed: 1998-01-09
Abstract: PROBLEM TO BE SOLVED: To reduce the burden of an event processor and to provide universal handling of events that are coped with by various event drive type systems and the facilitation of an event delivery mechanism especially when a network intervenes. SOLUTION: An event filter 201 refers to an event filter table 202 which describes the existence of needed event processing and sends only an event to be processed to an event processing part 300. Further, because an event can appropriately be carried out by another controller through a communicating part 400 even when a self-machine can not execute, the burden of the part 300 can be reduced to a considerable extent. Also, because a filter updating part 203 appropriately updates the table 202, the reference of selection of an event can dynamically changed and the efficiency of the entire system is further improved.

Filed: 1992-01-13
Abstract: PURPOSE:To hinder the deterioration of the light emission efficiency of a phosphor by applying a mixture liquid containing silic acid and ammonium oxalate to a glass panel in its area outside of the two primary color fluorescent film region prior to formation of an organic film. CONSTITUTION:A panel support holds a glass panel 1 on which a fluorescent film 2 is formed over a black matrix film 3. To the inner side face of the panel 1, a mixture liquid 6 containing 1.5wt.% ammonium oxalate and 0.3% silicic acid is applied from a nozzle 5 while the panel 1 is rotated. This is dried by an infrared heater 7, and educt crystals of mixture liquid are educed on the inner side face 8 of the panel 1 to produce a coarse surface. A filming film is formed over the inner surfaces of the panel 1 including side faces, and further thereover an aluminum metal thin film is formed by means of vacuum evaporation, followed by a bake-diffusion process. Because the thin film has a large bonding strength and large pin holes are formed, gas bleeding can be done well to decrease swell or tear of the thin film, and the light emission efficiency of phosphor is prevented from deteriorating.

Title: Leaf spring for axle suspending suspension
Inventor: SUGA KEISUKE
IPC: B60G11/04
Filed: 1999-01-11
Abstract: PROBLEM TO BE SOLVED: To reconcile security of excellent comfortableness and restraint of a windup phenomenon with a simple structure. SOLUTION: This leaf spring 10 forms an S shape where the anti-shackle side part 34 curves to the vehicle lower side in a side view and the shackle side part 36 curves to the vehicle upper side. Here, road surface reaction can be broken down into translation force and torque, but displacement in the direction for restraining a windup phenomenon can be obtained by using the translation force by forming the leaf spring 10 in an S shape. Thus, the windup phenomenon can be restrained. Moreover, since the leaf spring 10 is not constituted so as to use a separate part such as a windup stopper but is constituted so as to restrain the windup phenomenon by a shape pf the leaf spring 10 itself, the leaf spring can be formed as a simple structure. Since windup rigidity is not enhanced by increasing a spring constant in the vertical direction of the leaf spring 10, excellent comfortableness can be secured.
