Title: Lead-acid battery
Inventor: YOSHIDA TAKAMASA
IPC: H01M10/06
Filed: 1983-08-19
Abstract: PURPOSE:To increase performance and life of a lead-acid battery without additional special parts by filling the sufficient amount of electrolyte in a container, exposing a part of each anode plate from the surface of electrolyte, and installing a hole from which air flows into the container. CONSTITUTION:The sufficient amount of electrolyte 2 is put in a container 1 of a lead-acid battery so that part of electrolyte is fluid. The height of an anode plate 4 is made higher than that of a cathode plate 3, and the upper part of the anode plate 4 is exposed from the liquid level of the electrolyte 2. A hole is installed in the container 1 to always supply air in the battery. Since the battery has the sufficient amount of electrolyte 2 and large amount of sulfuric acid, the ratio of sulfuric acid which reacts anode active material in the exposed part 6 of the anode plate 4 is small and the effect on power generating reaction is also small. By selecting the area of the exposed part 6, absorption of oxygen gas is readily controlled.

Abstract: PROBLEM TO BE SOLVED: To provide an easy manufacturing method for a raw material for manufacturing a lightweight single head type piston by relatively unrotatably fixing hollow head portions of a body and closing members to each other. SOLUTION: A main body 102 has a tandem neck portion 106 made of neck portions of two single head pistons adjacently integrally connected to each other, and cylindrical hollow head portions 108 continuing from both ends of the tandem neck portion 106. The body 102 has engaging grooves 110 formed on inner peripheral surfaces of the hollow head portions 108 thereof. Fitting protrusion portions 120 of closing members 104 have ridges 124 formed on outer peripheral surfaces thereof. The outer peripheral surface of the closing member 104 is pressure-fitted to the inner peripheral surface of the body 102 and the ridges 124 are pressure-fitted into the engaging grooves 110, thereby preventing the closing member 104 and the body 102 from rotating relatively to each other. The closing member 104 may have engaging grooves and the body 102 may have ridges.  The closing member 104 and the body 102 may be prevented from rotating relatively to each other by the use of the snap-action-fitting utilizing engaging protruding portions and engaging recess portions, or the knurling or serration- fitting.

Title: Continuous casting method of metal
Inventor: OONAKA ITSUO
IPC: B22D11/06
Filed: 1982-09-01
Abstract: PURPOSE:To cast continuously metal with which breakout does not arise by storing the other liquid which does not react with the molten metal in a tank, and solidifying continuously the molten metal on the liquid surface while fluidizing said liquid at the speed equal to the outflow speed of the molten metal or above. CONSTITUTION:Continuous casting is pefformed by the following method in the case of using molten steel as the molten metal to be cast and molten lead as fluidized liquid, respectively: Molten steel 2 is supplied at a constant speed from the molten metal supply nozzle 2 of a holding furnace 1 for the molten steel onto the liquid surface of molten lead 4. The flowing speed of the lead 4 in this case is kept at the speed equal to the moving speed of the steel 2 or above. The covering of the surface of the molten lead having the larger specific gravity with the molten steel 2 is thus resulted in accordance with surface tension. Therefore the wall thicknesses in all parts are exactly uniform with the molten steel 2 having any broad width and thin wall thickness. The bottom surface in contact with the lead 4 and the top surface in contact with the tank atmosphere both have the luminance of a specular surface. The top surface of the steel 2 is gas and the casting mold of the bottom surface is the liquid surface, receiving no restrictions of solid. The generation of breakout is thus obviated at all.

Title: Formation of multilayer interconnection structure
Inventor: YAMAMOTO HIROSHI
IPC: H01L21/3205
Filed: 1993-06-23
Abstract: PURPOSE:To prevent a trench from being formed in a buried plug, by forming a metal film whose etching rate is small for an upper wiring metal film, on the upper layer of the buried plug. CONSTITUTION:A W metal film 17 formed on the upper layer part of a buried plug has an etching rate for RIE of an upper wiring metal film 18 which rate is smaller than that of the film 18, and is scarcely etched when exposed to etching gas plasma of the RIE. That is, the W metal film 17 functions as an etching stopper layer for the RIE of the upper metal film 18. Since a trench is not formed in the buried plug, and the upper layer wiring metal film 18 is patterned, electric connection between the upper layer wiring metal film 18 and a lower layer wiring metal film 13 is realized by the buried plug, in the state of sufficiently low contact resistance. Thereby wiring reliability can be improved.

Title: Control device for air conditioner
Inventor: ITOI YUICHI
IPC: F24F11/02
Filed: 1988-06-21
Abstract: PURPOSE:To control a room temperature including a quantity of heat generated from the physical action state of users and machines by a method wherein based on an output signal from a sound volume detecting means in a room, the number of users and a quantity of heat of a machine are determined, a necessary total quantity of heat is computed therefrom, and control is effected according to the computed result. CONSTITUTION:An audio signal obtained through the collection of a sound by means of an audio level detecting means 1 is amplified by an amplifier 2. A sensitivity regulating means 7 regulates the gain (amplification degree) of the amplifier 2. For example, the gain of the amplifier 2 is switched to three stages: 'loud voice', 'ordinary voice', and 'a low voice' according to the use of the room. This method detects the number of users in the room by means of the audio level according to the use condition of the interior of the room. When a machine with a high calorific value is a main factor by which an increase in the room temperature is caused, the pass band of a band pass filter 3 is set by a filter band set means 8 so that only noise generated by the machine passes. A signal processed thus described is fed to a microcomputer 4, and is converted to heat energy responding to the number of users and the level of noise of the machine.

Title: Driving method for liquid crystal electrooptic device
Inventor: SATO YUZURU
IPC: G09G3/36
Filed: 1987-06-19
Abstract: PURPOSE:To obtain area gradation without increasing the number of terminals by applying in-phase selection pulses which differ in crest value to two high conductors and applying a segment electrode with a signal pulse whose crest value is modulated with image information. CONSTITUTION:High conductors 31 and 32 are provided to two opposite sides of a common electrode 33 one to one. Then two kinds of selection pulses which are in phase, but different in crest value are applied to the conductors 31 and 32 and the signal pulse whose crest value is modulated according to the image information is applied to the segment electrode 34. A voltage applied to a liquid crystal layer, therefore, is not uniform in one picture element, but generates a voltage gradient in a (y) direction. Then when the signal pulse is varied in crest value within a specific value, the voltage gradient also varies and the area of an area of inversion varies. In this case, only the electrode 33 is provided with the conductors 31 and 32, so the number of terminals is double as large as that on a common side. Consequently, an increase in the number of terminals is suppressed and area gradations are obtained.

Abstract: PURPOSE:To prevent a deterioration such as the scattering of a transferred image by making a voltage applied to a transfer means under a specific condition lower than that applied to the transfer means when a recording medium is in contact with a recording medium guiding member. CONSTITUTION:The voltage applied to the transfer means after the recording medium P fed to a transfer part passes through the guiding member 7 leading the recording medium P to the transfer part is made lower than that applied to the transfer means while the recording medium P is in contact with the guiding member 7, so that a transfer current is reduced and the scattering phenomenon of the image capable of being transferred from an image carrier 1 to the medium P can be reduced. At this time, through transfer efficiency is reduced, the dropping level of the voltage applied to the transfer means after the tailing edge of the medium P fed to the transfer part passes through the guiding member 7 leading the medium P to the transfer part is set in a range where the scattering phenomenon of the image to be transferred can be reduced and the transfer efficiency not causing any trouble in practical use can be obtained, so that an excellent transfer reduced in the scattering in all areas from the leading edge to the tailing edge of the medium P can be performed.

Abstract: PURPOSE:To prevent video signals longer or shorter than one frame from being recording during one rotation of a disc by terminating recording with the output of a rotation detecting means if the rotative speed of the disc is deviated from a prescribed value during recording. CONSTITUTION:If the rotative speed of a motor is varied by the variation of a power source voltage or the like during recording to cause a phase difference between frame pulses generated from an input video signal and recording positioning mark pulses, this state is detected by a motor lock detecting circuit 8p, and a motor lock signal (e) is set to the low level. An edge detecting circuit 24 consisting of a delay circuit, which consists of a resistance 24a and a capacitor 24b, and an exclusive OR circuit 24c detects the edge of the motor lock signal (e) and inputs a reset pulse to a gate circuit 11d through an OR circuit 25, and a REC gate signal is switched to the low level to terminate recording. Thus, video signals longer or shorter than one frame are prevented from being recorded during one rotation of the disc.
