Title: Cooling parts for electronic device
Inventor: KIMURA NAOKI
IPC: H01L23/427
Filed: 1999-01-13
Abstract: PROBLEM TO BE SOLVED: To improve the capability of cooling by forming cooling parts of copper alloy containing the specific amount of copper to which cold-working is applied at a specific working rate. SOLUTION: It is desirable that cold-working rate be 97% or more because cold-working is applied to copper alloy at the increasing working temperature of 250 deg.C or less to significantly decrease a thermal expansion coefficient. It is also desirable that the copper alloy containing copper of 50 wt.% or more contain copper of 70 wt.% or more, if possible, 80 wt.% or more. The copper alloy may be, for example, copper alloy containing Cr of 10 to 30 wt.%, copper alloy containing the suitable amount of at least one element from among B, N, C, Si, P, Mg, Co, Ag, Be, Al, Ni, Zn, Ti, Sn, and Zr in addition to the above Cr, copper alloy of a Cu-Mo group, or copper alloy of a Cu-Cr-Mo group.  Thus, since copper of 50 wt.% or more is contained, thermal conductivity is high, the cold-working rate of 70% or more decreases a thermal expansion coefficient, which makes the copper alloy suitable for cooling semiconductor elements, etc.

Title: Cylindrical battery with spiral electrode
Inventor: TOBISHIMA SHINICHI
IPC: H01M10/05
Filed: 1992-01-20
Abstract: PURPOSE:To provide a cylindrical battery with spiral electrodes which has no irregular winding of the electrodes but has the function of cutting off a current when an overcurrent flows and abnormal temperature rise occurs and of realizing a reusable condition when temperature drops. CONSTITUTION:A positive electrode 2 and a negative electrode 4 are formed with electrode sheets, between which a separator 3 is placed, and then made into spiral shapes which are filled in a bottomed cylindrical battery can 8 to form a cylindrical battery. A hollow cylindrical or columnar spindle 1 is put into the center of the positive electrode 2 to avoid the winding shift of the electrode sheets. The spindle 1 is formed of an element which is increased or decreased in electric resistance with the temperature rise or drop of the battery so that the true temperature of the spiral electrode can be accurately and promptly detected in a range of the whole electrode to ensure cut-off of a current with electric resistance increased when temperature rise occurs in the battery and to keep the battery stable. When the temperature of the battery drops down enough to provide normal battery performance, a current can flow with decreased electric resistance to realize a reusable condition.

Title: Spread spectrum communication equipment
Inventor: HARADA HIROSHI
IPC: H04B1/69
Filed: 1992-01-20
Abstract: PURPOSE:To miniaturize a connector and to reduce cost by providing a second- order modulation part and a second-order demodulation part to turn a signal inputted into the connector to spread spectrum and inversely spread spectrum. CONSTITUTION:A slave unit 12 executes the spread spectrum modulation of voice signals and the radio transmission. After a connector 16 receives radio waves from the slave unit 12 by a connector antenna 17, the radio waves are converted to a prescribed frequency band lower than a radio frequency band. Further, to that signal, spread spectrum modulation is executed by a second diffusion code, for which coding velocity is higher than that of a spread spectrum code and spread is executed over a wider band, at the slave unit 12 by using an SS second-order modulation part 19, and the signal is outputted through a wide band transmission line 22 to a controller 21. Since the transmission line 22 is connected to plural units 16 in common and signals are surely demodulated at the connector and the controller while preventing radio interference any different peculiar code is allocated to the second diffusion code used at the unit 16.

Inventor: TANAKA YOSHIYUKI
IPC: F02D41/06
Filed: 1983-01-20
Abstract: PURPOSE:To eliminate the instability of idling and the occurrence of engine stall, by carrying out the increment of fuel when the temperature of engine cooling water is high upon starting of the engine. CONSTITUTION:Whether the temperature of engine cooling water reaches a predetermined temperature (for example, 110 deg.

Title: Novel heat-sensitive recording material
Inventor: KIMURA SHIROU
IPC: B41M5/323
Filed: 1979-01-26
Abstract: PURPOSE:To obtain a clear color developed picture by a method wherein a p-halide- N-methylaniline derivative is used as the coloring matter forming matter of heat- sensitive recording. CONSTITUTION:A heat-sensitive recording material is gained in such a manner that an applying liquid is prepared which is manufactured by pulverizing a specified p-halide-N-methylaniline derivative, a catalyst, such as, a lewis acid, a solid acid, etc., a filler, an additive, such as, a lubricant, etc. and by dispersing them into a binding agent, and applied or impregnated to a proper sheet and dried. Here, the p-halide-N-methylaniline derivative is colorless crystals in an ordinary state, but forms triphenyl-methane dyes by heating and melting the derivative. It is because dyes are formed by the change into a radical or an rearrangement reaction of the said compounds. Since heating temperature is not constant by the kinds of the said compounds but is generally not less than 40 deg.C, the time of color development can be shortened while the titled material has sufficient light resisting properties and stability.

Title: Rotary thpe heat pipe
Inventor: FUJII MASAO
IPC: F28D15/02
Filed: 1985-01-17
Abstract: PURPOSE:To improve a thermal conductivity of cooling part and to make a shortened axial length of compact size by a method wherein working fluid is filled in a clearance between the inner wall surface of an outer cylinder of the heated double-wall cylinder and an outer wall surface of the inner cylin der to be cooled. CONSTITUTION:A clearance formed between the inner wall surface of the outer cylinder 3 and the outer wall surface of the inner cylinder 4 forms a hollow sealed container and then the working fluid is filled in the container. With this arrangement, the outer wall surface of the outer cylinder 3 becomes a heating part A and the inner wall surface of the inner cylinder 4 becomes a cooling part B. Steam generated by heating the heater part A and heated from the liquid film 2 is condensed and liquified at the outer wall surface of the inner cylinder 4 acting as the cooling part B. However, the steam is splashed by a centrifugla force and circulated back to the liquid film 2 of the heating part A. Therefore, since the cooling part B has no liquid film 2, the thermal conductivity at the cooling part B is substantially improved. Since the cooling part B is in parallel with the heating part A, the axial length of the unit is shortened to make a compact sized-unit.

Title: Developing method
Inventor: OKAWA SHIGEKI
IPC: G03G13/08
Filed: 1989-01-17
Abstract: PURPOSE:To obtain a good image having desirable image density in a stable state for a long term by using initial developer for throwing in at an initial stage and replenishing developer for replenishment and mutually changing each magnetic characteristic of magnetic toner in both developer. CONSTITUTION:The transfer of the magnetic toner(the consumption of the toner)in a developing area depends on a developing electrolytic power and a magnetic attraction force. The developing electrolytic power is decided based on the potential difference between a developing bias potential impressed on a developing sleeve 4 and an electrostatic latent image potential, and the charge of the magnetic toner. In order to make the density of an image dense, it is good that the power for making the magnetic toner in the developing area transfer becomes stronger. It is good that the transfer power of the magnetic toner is changed between at the time when the image density at the initial stage of printing is not enough to be satisfied and at the time except that. That means, the transfer power of the toner for the initial developer is made stronger and the transfer power of the toner for a replenishment is made smaller. Thus, the high image density can be obtained in a stable state from the initial time of forming the image for a long term.
