IPC: H01L27/12
Filed: 1984-07-16
Abstract: PURPOSE:To obtain the titled substrate easy of forming a semiconductor device the bottom of which is covered with insulator, by forming an ingot by alternate lamination of a single crystal layer to form the element and an insulator layer. CONSTITUTION:After an Si single crystal 21 is formed to a required thickness, an SiO2 22 is formed to a required thickness, and next an amorphous Si 23 is formed to a required thickness; then, the amorphous layer 23 is single-crystallized with laser beams B. Using this as a seed, a single crystal layer 21' is grown, and an ingot is produced by repeating the formation of SiO2 or the like as conventional. Using a substrate 31 with an SiO2 layer 22 thus inserted between the single crystal layers 21 and 21', elements are isolated 13 by providing grooves in required regions and filling them with SiO2; then, a PchMOSFET is provided in an N-well 2, and an NchMOSFET in the other well, thus obtaining a C-MOS device. Use of this substrate enables the elements to be completely covered with an insulation film without the decrease in characteristic, yielding a high industrial value.

Abstract: PURPOSE: To prevent hunting phenomenon of spool by forming the damping chamber between the spool end part and the bag-shaped bush and connecting the chamber by a small port with the pocket between the outer end surface of the bush and the pressing plate.  
     CONSTITUTION: When the main switching valve 15 is switched to the X position, pressurized oil flows into the damping chamber 7 through the port 20 of the counterbalanching valve 1, the passage 21, the left chamber 12, and the check valve 13 to shift the spool 2 in the A direction resisting the spring 6'. Pressurized oil also flows to the port 25 through the chamber 23 and the check valve 24 to act upon the oil hydraulic pressure motor 16, and when the chambers 22', 23' are connected by the shifting mentioned above, the discharging side of the oil hydraulic pressure motor 16 is connected to the tank 19 and the motor 16 is turned in the direction R. In this case, if strong damping force is generated, the bush 4' is lifted from the pressing plate 3' to release pressurized oil in the chamber 7' through the small port 9' and the pocket 8' to avoid generation of hunting.

Title: Gear cutting method for warm wheel
Inventor: HIGUCHI MEGUMI
IPC: B23F11/00
Filed: 1985-07-09
Abstract: PURPOSE:To avoid reduction of diameter of warm due to increase of gear ratio for same wheel base by increasing the diameter of cutter by the amount corresponding with separation from the wheel base of warm gear set and cutting the gear while inclining more than the crossing angle of both parts. CONSTITUTION:A hob 7 is positioned while separating by eg-e1 (eg, e1 are the pitch radius of cutter and warm) more than the wheel base (e) between a warm 1 and warm wheel 2 while the radius of hob 7 is increased correspondingly to cut the gear of warm wheel 2 while inclining the hob 7 against the warm 1 by the hob inclination angle (d). Consequently, the warm wheel 2 can be cut into such profile as gearable with the warm 1. Since the diameter of hob 7 can be made larger by eg-e1 than the warm 1, the diameter of hob 7 is never reduced so much as to disable manufacture, or to degrade the productionability of warm wheel 2 considerably or not to withstand against the cutting load even under such specifications of warm gear as to require reduction of diameter of warm 1.

Title: Prevention of freezing of tank ballast water in icy sea
Inventor: OGAWA KAZUO
IPC: E02B17/00
Filed: 1985-07-09
Abstract: PURPOSE:To greatly reduce the cost of fuel necessary for preventing freezing of tank ballast water by a method in which the temperature of water in the ballast tank is monitored by a temperature sensor, and when the water temperature is lowered to near the freezing point of sea water, sea water is introduced into the lower inlet of the ballast tank. CONSTITUTION:In ballast tanks 2a-2n, the temperature of water in the internal upper part of the tanks 2a-2n is monitored by temperature sensors 4a-4n. When the water temperature in the ballast tank 2a is lowered to near the freezing point of sea water, a valve 6a is opened and a comparatively high temperature of sea water is introduced into the tank 2a. When the sea water temperature in the tank 2a reaches a comparatively high one, the valve 6a is closed to prevent the freezing of the ballast water. A boiler for preventing the freezing of ballast water in the tank inside a marine structure in the icy sea area can thus be used only for preventing the freezing of oil and working water.
