Title: Solid-state image sensing device
Inventor: KADOWAKI MASAHIKO
IPC: H04N5/335
Filed: 1986-09-03
Abstract: PURPOSE:To reduce the manufacturing costs, by omitting an Au metallized part at a part of a mounting part, on which a chip is not mounted, thereby reducing the amount of Au by that quantity. CONSTITUTION:Au metallization 2 is applied only on the central part of a chip mounting part 1 of a package. The size of the metallized part 2 is made smaller than the size of a color solid-state image sensing element, which is mounted on the part 2, by 0.7 mm. Even if a pellet is attached by using this pattern, no problem occurs not only in wettability of Ag paste but also in the characteristics of the element. Thus, the area of the Au metallized part of the mounting part becomes about 50% the conventional area. The unit price of the package can be reduced to a large extent.

Abstract: PURPOSE:To enable the image of an inspection of a track structure be accurately picked up, independent of the speed of a vehicle carrying an inspection device, by processing the measurement signal of a track structure according to the vehicle speed, and detecting a specific structure necessary for picking up the image of the inspection object on the basis of the aforesaid signal processing. CONSTITUTION:A track structure-related signal outputted from a track structure measurement means 1 is shaped with a measurement signal processing means 2, and the signal so shaped is made to pass through a track structure detection means 5, thereby detecting the specific structure of a track. Also, the image of an inspection object on the track is picked up with an image pickup means 6 on the basis of the aforesaid detected signal. In this case, signal wave shaping with the means 2 needs to be performed, depending upon the travel speed of a vehicle. The travel speed, therefore, is measured with a vehicle speed measurement means 3 and a signal processing control means 4 is made to function on the basis of the measured vehicle speed. The image of all inspection objects, then, can be properly picked up, even if many objects are existing on the track at random and a vehicle carrying a track inspection device is travelling at a high speed.

Title: Nickel alloy for heating element of preheating plug
Inventor: SHIRAISHI YASUHISA
IPC: C22C19/03
Filed: 1981-12-23
Abstract: PURPOSE:To provide a nickel alloy which is effective as preheating plugs that can start diesel engines in a short time, is inexpensive and is free from degradation in ductility by contg. a limited compsn. content of boron in nickel. CONSTITUTION:A titled alloy is a nickel alloy which consists of 0.01-20wt% boron and the balance substantially nickel, has excellent specific resistance characteristics at high temp. and is suited as a heating element for preheating plugs that can start Diesel engines in a short time. With said alloy, the inclusion of boron as oxide into nickel in the casting stage of the alloy is obviated; therefore, initial ductility is retained, and the reduction in the cost of the heating elements is made possible by the use of inexpensive boron. The reason for limiting the amt. of the boron to be added to the above-mentioned limits lies in that at <=0.01% there is no effect in preventing the growth of crystal grains and in excess of 20% the workability is degraded. The preferable contents are 0.1- 1%. Part of nickel may be substd. with <=1% yttrium to improve oxidation resistance.

Title: Seal for hydraulic machinery
Inventor: TANABE SEIICHI
IPC: F03B11/00
Filed: 1986-09-05
Abstract: PURPOSE:To prevent tensile force from occurring, by forming a seal part in an orthogonal direction with a runner turning center shaft, and installing a projection at the outer circumferential side of the seal of a runner part. CONSTITUTION:Seal parts 2-5 consist of abrasive resisting parts 10-17 and made up of a nonmetal material of more than 1,000 in Vichers' hardness. These seal parts 2-5 are formed in an orthogonal direction with a turning center shaft 6 of a runner, and a projection part 20 out of the runner is installed in an outer circumferential part of an antifriction material. Therefore, centrifugal force to be produced in this antifriction material during rotation of the runner is supported by the projection part 20, whereby any tensile force will not happen in the antifriction material. And, a nonmetal material high in hardness is usable for a sealant, thus abrasion is reducible.
