Title: Lead-acid battery
Inventor: SUZUI YASUHIKO
IPC: H01M10/12
Filed: 1987-10-02
Abstract: PURPOSE:To increase the life of a battery at high temperature by using a Pb-Sb base alloy in a positive grid and a Pb-Ca alloy in a negative grid, and using paste mainly comprising lead powder containing red lead oxide, water, and sulfuric acid as a positive active material. CONSTITUTION:In a lead-acid battery using a Pb-Sb base alloy in a positive grid and a Pb-Ca base alloy in a negative grid, paste mainly comprising lead powder containing red lead oxide, water, and sulfuric acid is used as a positive active material. As a result, the porosity of the active material is increased and the roughness factor is also increased to increase the charge acceptability of a positive electrode. If the content of red lead oxide is increased, the charge acceptability is increased, but if the centent is increased more than 50wt.%, the life at normal temperature is decreased. The optimum content of the red lead oxide is 10-50wt.%. The life at high temperature is increased without the sacrifice of the life at normal temperature.

Title: Heel fastener of ski boot having ski brake therein
Inventor: TAKAHASHI TORU
IPC: A63C9/084
Filed: 1987-10-03
Abstract: PURPOSE: To cancel a problem such as difficulty in ski boot wearing operation caused by the excess backward move of bindings or a change in the height position of a ski brake caused by a front pressure change by letting the ski brake take a braking or stopping attitude while being interlocked with only the vertical turning operation of a pedal pivotally supported on a heel receiver. CONSTITUTION: When there is no ski boot 3 within the binding, no pressure is exerted upon a pedal 4 so that the pedal 4 can be moved up by the pressure of a spring 9 and a cam 7 can be turned to the left and as a result, a ski brake 13 turns down to a ski and takes the braking attitude. When there is the ski boot 3 within the binding, on the other hand, the pedal 4 is pushed down and turned so that the cam 7 is also turned to right against the pressure of the spring 9 and therefore, a brake joint 10 prepared integrally with the cam 7 essentially and the ski brake 13 turn up to the ski and take the standstill attitude.

Title: System for recording servo data of magnetic recorder
Inventor: SUZUKI KOUJI
IPC: G11B21/10
Filed: 1987-10-06
Abstract: PURPOSE:To make quantity that a head is applied to servo data large and to obtain a detection signal whose S/N is good by recording the servo data more widely than a track pitch. CONSTITUTION:The servo data to executed a track servo to a medium to be used for a floppy disk drive device (FDD) and normal data are formatted by the head whose core width is wider than the track pitch. In this case, when a normal data part is formatted, it is recorded by dislocating the position of the head from the central position of a track and one part is overwritten and recorded when it is formatted to the next track. Consequently, by the head wider than the track pitch suitable for recording a servo data part, the recording of a format without dislocating the position of the data part from a target position even when the normal data part is formatted can be executed. Thus, a signal voltage from the servo data becomes large, the S/N of the signal voltage becomes high and track servo accuracy is improved further.

Title: Shipping system
Inventor: MIYAZAKI YUUTA
IPC: B60P3/22
Filed: 1997-09-16
Abstract: PROBLEM TO BE SOLVED: To prevent errors in discerning yes or no in execution of gas purging when loading is made at an oil tank station that is different from an oil tank station whereat previous loading is made. SOLUTION: A shipping system at an oil tank station is constructed of a shipment control device 4 for a shipping apparatus 1 set up at a shipping site, a hatch setting device 2 installed in an office separated from the shipping site and a host computer 3 serving as a shipment control computer. The hatch setting device 2 judges, based on trip information registered in reserved data, whether or not the previous loading to a tank truck 5 is made at another oil tank station. In the case where judgement is made that the previous loading to the tank truck 5 is made at another oil tank station, necessity of gas purging is assigned to each of hatches.  Therefore, when the previous loading is made at another oil tank station, necessity of gas purging is set to the tank truck 5 regardless of the kind of oil on the previous loading, and thereby loading at a different oil tank station can be executed safely.

Filed: 1988-10-05
Abstract: PURPOSE: To allow a spring to relatively slightly move by fixing or holding the spring to a connecting element of pivotal prongs, and supporting a free end portion of the spring to a base plate. CONSTITUTION: A connecting element 3 for fixing pivotal prongs 4 for forming a U-shaped holding arm of sheets defining holes with fixed prongs 2 is rotatably held on a base plate 1. The element 3 has a reinforcing rib 10, and the prongs 4 are inserted into a web portion. The element 3 holds the closure mechanism against a spring 14 provided between the plate 1 and the element 3.

Title: SiC SINTERED COMPACT
Inventor: KINUGASA HISASHI
IPC: C04B35/565
Filed: 1999-09-06
Abstract: PROBLEM TO BE SOLVED: To prevent lowering of strength caused by fine scratches and micro- cracks formed by polishing, or the like, by subjecting an SiC sintered compact to heat treatment at a specified temperature under a vacuum atmosphere so that the crystal grain boundary is formed, after subjecting a prescribed part of the SiC sintered compact to surface finishing by polishing. SOLUTION: An SiC sintered compact obtained by sintering is subjected to surface finishing by using a powder such as a diamond powder so as to secure prescribed dimensional precision and surface accuracy sufficient to be used as a sliding member, or the like. Thereafter, the SiC sintered compact is heat treated at a temperature of >=1,000 deg.C, preferably >=1,300 deg.C under a vacuum atmosphere. Thereby, thermal decomposition and evaporation and rebinding of SiC bonding chains being cut are allowed to occur, and further, the crystal grain boundary is formed at an unstable layer of the upper layer of the finished face containing fine scratches and micro-cracks formed by polishing.  The fine scratches and micro-cracks are eliminated by the change of the structure at the surface layer, and the lowering of being strength of SiC sintered compact having small fracture toughness can be prevented.
