Title: Cylinder block structure for v-shaped engine
Inventor: YAMADA SATOSHI
IPC: F01M5/00
Filed: 1991-09-26
Abstract: PURPOSE:To save space by enabling the cooling of oil without installing a cooling device such as an oil cooler. CONSTITUTION:Stepped portions 9 are formed on a recessed portion 8 of a cylinder block 1, while a cover plate 11 is fastened by means of bolts 13 on the stepped portions 9. A resultant space 11 surrounded by the cover plate 11 is a cooling water passage 14. The cooling water passage 14 is connected to a water inlet on a radiator outlet side. A main oil passage 25 is formed in the cylinder block 1 in a longitudinal direction of the cooling water passage 14. Then, the cylinder block 1 itself serves as a cooling device for oil and a pipeline therefor. The oil flowing inside the main oil passage 25 is cooled by the cooling water flowing inside the cooling water passage 14 adjacent thereto. It is unnecessary to saparetely provide a cooling device for oil, and a pipeline for connecting the cooling device to the engine.

Abstract: PROBLEM TO BE SOLVED: To drive a wiper device by using solar cells capable of being unified with a road sign and having a comparatively small area, and to clean the surface of the traffic sign such as a delineator automatically at low cost. SOLUTION: In the delineator, a wiper blade 13 is rotated so as to wipe the surface of a reflecting plate 10 centering around a shaft 12 by rotating a DC motor 16 connected through a reduction gear mechanism 17. The DC motor 16 is joined with solar cells 18 through a feed control circuit 19 consisting of a capacitor 20, a switching transistor 21, a voltage sensor 22 and a diode 23 for preventing a reverse current. Electricity generated by the solar cells is stored in the capacitor, and the voltage sensor outputs a signal to turn the transistor on when voltage at both ends of the capacitor reaches a specified value or more. Accordingly, the transistor is opened and a current flows through the DC motor from the capacitor. When voltage at both ends of the capacitor falls below a specified value or less, the voltage sensor turns the transistor off.

IPC: G06F3/14
Filed: 1989-09-25
Abstract: PURPOSE:To reduce an influence upon the display of an active window regardless of the existence of many invisible windows by displaying an invisible window existence display area at the time of the existence of invisible windows. CONSTITUTION:An invisible window display box 400 is displayed when one or more windows in the completely invisible state (a window group indicated by broken lines) exist. When the invisible window display box 400 is clicked with a mouse, a pop up window 500 is displayed, and icons 600 of invisible windows are displayed in this window 500. When one icon is selected from these icons 600 and is clicked with the mouse, the corresponding invisible win dow is selected as the active window. Thus, the invisible window display box is not displayed at the time of the absence of invisible windows, and an influ ence upon the display on the active window is reduced because the invisible window display box is displayed independently of the number of invisible windows.

Title: Manufacture of dust core from amorphous alloy
Inventor: SATO TAKASHI
IPC: B22F3/00
Filed: 1986-10-22
Abstract: PURPOSE:To obtain a material for a dust core with high magneticpermeability by a method wherein, after amorphous magnetic alloy powders are surface- treated by using a complex coupling material and the powders are pressurized to shape a prescribed form, the formed powders are heat-treated in the atmosphere of an inert gas at a temperature of 100 deg.C-550 deg.C. CONSTITUTION:After an insulating film for amorphous alloy powders to be used as magnetic powders is formed by using a complex coupling material and the powders are pressurized to shape a prescribed form, the formed powders are heat-treated. The heat treatment is executed in order to remove the strain of the alloy powders and to relax the structure; this treatment is indispensable to eliminate the secular variation. The temperature for this heat treatment depends on the composition; it is better to execute the heat treatment for 30 min-4 hr at a temperature which is by 50$-120 deg.C lower than the crystallization temperature. Regarding the atmosphere for this heat treatment, the oxidizing atmosphere is not preferable because the amorphous powders are oxidized easily. The most suitable atmosphere is an inert gas such as argon, nitrogen, hydrogen or the like.
