Title: Circle cutting device for paved road surface and cutting edge used therefor
Inventor: KATSUMOTO ISAMU
IPC: E01C23/09
Filed: 1992-11-19
Abstract: PURPOSE:To make the cutting of circles having different diameters possible without transmitting vibration occurring during working process to other parts by vertically providing a driving main shaft from an upper side, and protruding a cutting edge arm whose length is variable. CONSTITUTION:A rear cover 116 is opened to open the rear part of the load carrying platform of a vehicle. Next a cutting device 10 is fixed to a supporting face composed of the rear cover 116 and the rear end of the load carrying platform. The length of an arm 13 and a cutting edge 14 are properly selected. A handle 18a is rotatingly operated to move a supporting base 15 so as to position a plumb 38 at the center of a circle to be cut. A handle 27 is rotated to lower a diamond tip 42 at the lower end of the cutting edge 14 to a position where the tip 42 comes into contact with a road face. The arm 13 is rotated centering around the center P of the circle to move the cutting edge 14 along its circumference for circularly push-cutting the road face by the diamond tip 42. Thus since a support is not erected on the road face, vibration occurring during a work process is not transmitted to other parts, and the road face can be cut into an optional diametral shape by regulating the arm.

Title: Semiconductor element having fine wire structure and manufacture thereof
Inventor: NAKAGAWA KIYOKAZU
IPC: H01L29/812
Filed: 1993-12-10
Abstract: PURPOSE:To form an Si1-XGeX layer having the low density of a defect degree without reducing a mixed crystal ratio to obtain a high-efficiency light-emitting element and to make small the mean effective mass of electrons to obtain a high-speed field-effect transistor. CONSTITUTION:A fine wire structure consisting of an Si1-XGeX mixed crystal of a width of 10mum or narrower is formed on an Si substrate in parallel to the orientation <100> and a field-effect transistor using the fine wire structure as its channel or a light-emitting element using the fine wire structure as its luminous region is formed. Accordingly, a Ge concentration (x) can be made high by the fine wire structure without introducing a dislocation and the band discontinuous value of the heterointerface between the substrate and the fine wire structure is made two times larger or thereabouts than a conventional one. By this effect, an electron-hole confinement is effectively made to recombine. By forming the Si1-XGeX fine wire structure in parallel to the orientation <100>, the element is controlled utilizing a lattice mismatching to apply an unaxial compressive stress parallel to the orientation <100'> to the fine wire structure, the mean effective mass of electrons is made small and this field-effect transistor can obtain a high-speed performance by three times compared to a field-effect transistor using a conventional heterointerface.

Abstract: PURPOSE:To enable a hot water to be fed to a set water level and at a set temperature to be performed within a short period of time and automatically and to improve the convenience in use of the device by a method wherein a water amount adjusting valve is arranged at an automatic hot water feeding pipe and additional hot water supply and an additional heating are applied even in case that a water in a bath tub is reduced and a hot water temperature is decreased. CONSTITUTION:When a remained hot water of the previous day is utilized to boil up a bath tub water or when a volume of hot water is decreased during taking a bath or its temperature is decreased, a turning on of a switch for a controller causes a water volume adjusting valve 15 to be opened with a signal from a controller device 13 and then the hot water is added to the bath tub 4. A degree of opening of the water volume adjusting valve 15 is varied in such a way as the temperature at this time becomes high and then the amount of water is adjusted and hot water is flowed. That is, a temperature sensor 14 detects a temperature of hot water fed to the bath tub 4 and a signal is sent to the water volume adjusting valve 15 from the control device 15 in such a way as it becomes a set temperature so as to adjust the flow rate. If the bath tub water is accumulated from a connection port between the bath tub 4 and the additional heating pipe 9, the additional heating pump 6 is operated to circulate the bath tub water and then the water is heated by the additional heating heat exchanger 3. With this arrangement, it is possible to set a proper amount of bath tub water within a short period of time, resulting in that its convenience in use is improved.
