Title: Electric power source for arc welding
Inventor: SAKABE AKIRA
IPC: B23K9/09
Filed: 1981-11-20
Abstract: PURPOSE:To permit supplying of voltage with which immediate welding is possible in TIG welding as well by providing an error amplifier which amplifies the difference between a feedback output and a reference output and outputs an control signal to a control circuit, a comparator for the output control circuit and the wave from a normally operating saw tooth wave generator, a starting signal generator which receives and outputs a welding start signal, and a switching circuit which receives the starting signal and outputs the output control signal to the comparator. CONSTITUTION:A starting signal generator 11 is turned off and a switching circuit 12 is turned on. A saw tooth wave generator 9 is under oscillation, but since a switching circuit 12 is on, the actuation of a driving signal generator 10 by a comparator 8 is prohibited, and the output of an electric power source for arc welding is 0. In the stage of starting of welding, a starting signal generator 11 emits a starting signal on receiving of the welding start signal. Then, the circuit 12 goes off, and immediately the comparator 8 starts outputting the output control signal. Thus a switching circuit 2 operates immediately and voltage is supplied to load 5.

Title: Vegetable preserver
Inventor: NISHIYAMA TAKANOBU
IPC: F25D25/00
Filed: 1990-07-14
Abstract: PURPOSE:To maintain the inside of a preserver in a highly humidified state while preventing dew condensation on the inner wall of the preserver and to make the temperature in the preserver uniform so that vegetables can be preserved stably by a method wherein the temperature inside the preserver is kept around 1 deg.C and the humidity inside the preserver is made almost saturated by a means for cooling the inside of the preserver which is installed around the preserver and an air current is formed along the inner wall of the preserver. CONSTITUTION:Vegetables 19 are put in basckets 13 and a refrigerant is made to flow through an evaporator 8 of a freezer which is provided around sides of an outer box 1a, so that temperature in the preserver 1 is made as low as about 1 deg.C at which the vegetables are preserved. The humidity in the preserver 1 is kept saturated. A fan 17 is driven, and air supplied by the fan 17 is made to circulate in such a way that the air enters a hollow part 15 and is jetted out of a slit 18 to flow along an inner wall of an inner box 1b, and then flows along a bottom surface of the inner box 1b and finally returns to the fan 17 through between the basckets 13. In this instance, an air bordering film part can be thin by the air jetted from the slit 18. As a result, temerature difference between on an inner wall surface of the inner box 1b and inside of the inner box 1b can be made small enough to prevent dew condensation on the inner surface of the inner box 1b. Thus, humidity in the inner box 1b can be prevented from decreasing, and therefore, the vegetables can be preserved stably in a highly humidified state.

Title: Information retrieval supporting system
Inventor: NAKAYA YOSHIO
IPC: G06F17/30
Filed: 1990-07-13
Abstract: PURPOSE:To attain more powerful similarity retrieval by classifying a keyword into 'relation name' and 'a view point' by a similarity relation storing means and executing the standardization of the similarity relation of the keyword. CONSTITUTION:A similarity relation storing means 11 classifies a keyword into a 'relation name' and 'a view point' as similarity relation and represents the representing form of the relation between vocabularies with 4 set list such as a vocabulary 1, the relation name, the view point and a vocabulary 2. For the relation of 'an engine' and 'power' for instance, the former can be represented to be the mechanical component of the latter, 'the component' is equivalent to the relation name and 'mechanical' is equivalent to the view point. That is, it is equivalent to the power, the component, mechanical and the engine. Besides, when the view point is changed, it can be said that 'the engine' is the 'physical' 'component' of 'a vehicle.' That is, it is equivalent to the vehicle, the component, physical and the engine. In such a way, even when the relation name is same, the different vocabularies are related when the view point is changed. Thus, more powerful similarity retrieval is attained.

Title: Negative pressure-inducing liquid storage container, ink jet cartridge consisting of the container formed integrally with ink jet recording head, and manufacture of container
Inventor: MATSUMOTO HIDEHISA
IPC: B65D85/84
Filed: 1997-07-11
Abstract: PROBLEM TO BE SOLVED: To stably supply a liquid from the start of use with the help of a negative pressure by making an area excluding an area covering a casing and the liquid supply part of an inner enclosure and a pinch-off part, a face having the largest area and providing a deformation restricting member in an area excluding the peripheral part of the face which becomes the largest area face of the inner enclosure. SOLUTION: On the largest area face of an inner wall 102 of a liquid storage container, a reinforcing member 109 is formed, between the inner wall 102 and an outer wall, toward an area near a peripheral part from the center part of the largest area surface. Of an area, which is substantially of a planar shape, of the outer wall of an ink tank formed of polyhedrons, a part, without an angular part and the reinforcing member 109, of the peripheral part of the inner enclosure corresponding to the largest surface area, has a low strength so that the part without the angular part and the member 109 tends to be deformed to the liquid storage part side enclosed with the inner enclosure. In this case, the outer wall 101 works to control the displacement of the angular part of the inner wall 102, hence almost no positional fluctuation of the angular part.  Consequently, the working force of deformation by ink consumption and the working force of restoration to an initial state collaborate to stabilize a negative pressure.
