Title: Lead storage battery
Inventor: SHINPOU MASANOBU
IPC: H01M4/82
Filed: 1983-11-01
Abstract: PURPOSE:To obtain a light lead storage battery of good performance by using an expanded grid made of a lead alloy containing small percentages of antimony and arsenic. CONSTITUTION:A grid is made by heating a lead alloy sheet containing 0.8- 2.0% of antimony and 0.01-0.2% of arsenic to 190-300 deg.C, then quenching the heated alloy before it is expanded. When the content of antimony is at least 0.8% of the alloy sheet, its strength and corrosion resistance are improved by performing the heating and quanching. When the content of antimony exceeds 2.0% of the alloy sheet, its corrosion resistance is deteriorated and self discharge develops in a higher possibility in a battery constituted using the grid of this invention. Although the strength of the grid is widely improved by adding at least 0.01% of arsenic in forming the alloy sheet, addition of more than 0.2% of antimony can not achieve any higher effect and will result in a deteriorated corrosion resistance. In addition, the alloy sheet is required to be heated to a higher temperature as the content of antimony is lower.

Title: Magnetic structure and preparation thereof
Inventor: MASUTAFUA PINABASHI
IPC: H01L43/12
Filed: 1994-08-31
Abstract: PURPOSE: To reduce fluctuation in asymmetry in the output voltage of a magneto-resistive head by avoiding the partial fluctuation of chemical and physical characteristics in the magneto-resistive layer. CONSTITUTION: In a magneto-restive read converter, a material inactive on a soft magnetic thin film magnetic bias layer is formed on the surface of a substrate before a soft magnetic thin film is adhered. The substrate surface layer 42 of metal such as Cr to Ta is used. Such metal has high resistance by partial oxidation at the time of adhesion on the substrate 40 and reduces the shunt of sensing current passing through the magnetic resistant layer. Furthermore, it operates as a barrier for protecting the soft magnetic thin film from the contamination of a substrate interface. The surface layer sets a soft magnetic thin film magnetization direction to a direction which is clearly formed and therefore magnetic instability is reduced.

Title: Stirling heat engine
Inventor: SAKAI MASAHIRO
IPC: F25B9/14
Filed: 1987-08-20
Abstract: PURPOSE:To make a cold side heat exchanger and a jacket cooler both miniaturizeable and simultaneously cooling medium circulating pump driving force abatable by using a refrigerant which produces a two-phase change as a cooling heat transfer medium available in the cold side heat exchanger. CONSTITUTION:As a medium to be cooled by a cold side heat exchanger 22, such that produces a two-phase change, for example, flon 11 or the like is used. Such heat transfer medium is circulated by a refrigerant pump 15, whereby evaporation can be done at the cold side heat exchanger 22 and condensation at a cooling heat recovering heat exchanger 12, respectively. Forced evaporation and condensation heat transmissibility at this time is of very high value, and each heat transfer area of these heat exchangers can be made smaller. In addition, since it utilizes latent heat, circulation value is also reducible. From these reasons, each of these heat exchangers 12 and 22 can be miniaturized and simultaneously driving force of the refrigerant pump 15 is abatable.

Filed: 1989-08-10
Abstract: PURPOSE:To feed electricity at need by providing an electronic flash light device, deciding an input signal, and operating a boosting circuit forcibly when the input signal is on and controlling a light emission preparation state on a camera side. CONSTITUTION:The signal which turns on or off the electronic flash light device forcibly is inputted from the output means of a camera main body to a terminal ST1. The signal width of the input signal is detected by a detecting circuit TM and outputted to a microcomputer (muC3). The microcomputer muC3 decides whether the input signal is a forcible on or off signal according to the signal width. When the input signal is the forcible on signal, a light emission control means LEC controls light emission to operate a boosting circuit D/D, which boosts the voltage of a battery into a high voltage. When the input signal is the forcible off signal, on the other hand, the D/D is not operated. Consequently, the circuit D/D controls the operation with the control signal from a camera main body to emit flash light, so the necessary electric feeding is performed.
