Abstract: PROBLEM TO BE SOLVED: To safely and cleanly perform the grinding work without generating environmented pollution by collecting the dust of coating film, which is peeled from a surface to be ground by the injection of the grinding material, for recovery with the remote control operation. SOLUTION: A control device 10 is operated so that the grinding material 1 is injected from a grinding device 2 to a surface S to be ground. This grinding material 1 collides with the surface S to be ground, and the coating film is peeled by the impact thereof. Dust of the peeled coating film and the grinding material 1 after the grinding is sucked by the rotation of a separating rotary blade 59 through a suction pipe 13, and supplied to a grinding material separating and recovering device 5. At this stage, the only grinding material 1 is separated from the compressed air so as to be recovered in a housing box 57, and the air, which includes the residual dust, is supplied to a dust recovering and selecting device 7.

Abstract: PURPOSE:To obtain the titled MOSFET having small fluctuations in mutual conductance and a small parasitic capacitance by a method wherein the oxide film in the vicinity of a drain region is densely formed, the electric field in the neighborhood of the oxide film is made weak, and the reduction in the hot carrier to be injected into the oxide film is achieved. CONSTITUTION:An oxide film (SiO2 film) 2 is laminated on a p-type silicon substrate 1, and a gate electrode 3 consisting of polysilicon is formed by performing an etching. As-ions are implanted on source and drain regions 4 and 5 using the resist film, whereon an aperture is perforated, as a mask. Then, an Si3N4 film of 1000Angstrom  in thickness is grown in a vapor phase on the whole surface. Subsequently, an etching is performed on the Si3N4 film using an RIE method. As the RIE method is anisotropic, the nitride film 6 remains on a plane part. Then, the film thickness of an oxide film is grown as far as to the region located in the vicinity of a p-n junction part by performing a thermal oxidization. Lastly, the nitride film is removed by etching, an insulating film is formed on the whole surface, a contact hole is perforated, and a wiring layer is formed.

Title: Electric water heater
Inventor: YAMASHITA YOSHIHIRO
IPC: A47J27/00
Filed: 1995-07-27
Abstract: PROBLEM TO BE SOLVED: To improve the baking detecting performance during the boiling keeping operation in a simple constitution. SOLUTION: When a boiling control means 6 is shifted to the boiling extension operation, a baking detecting means 7 adopts a designated gradient determination value among plural gradient determination values regardless of the heating start temperature and detects that the temperature rise gradient based on a temperature signal input from a temperature detecting means 5 is more sharp than the designated gradient determination value to control a current application control means 3 to intercept the application of a current to a heating means 2.  Thus, a small quantity of low-temperature liquid can be boiled without baking detection in error in a simple constitution, and even if a liquid is entirely discharged to the outside of a container 1 during the boiling keeping operation, baking is quickly detected to interrupt the heating means 2 so that the damage of the bottom of the container 1 can be prevented.

Title: Semiconductor memory
Inventor: KURIHARA RYOICHI
IPC: G06F12/00
Filed: 1996-07-22
Abstract: PURPOSE: To make a high speed setting possible by setting a simultaneous reading range of successive plural bits in the direction of row by a start/end pointer without adding a new constitution. CONSTITUTION: At a pointer-set-cycle 1, when RAS falls, CAS and WE detect a high level and BW detects a low level before an address Ayi is fetched and decodes by a column decoder 1. And the bit selected at the column address Ayi of a pointer register 3 is set to 1. Namely, a pointer is set to the bit selected at the address Ayi of the register 3. Similarly, at the pointer-set-cycle 2, the column address Ayi is fetched and set to the register 3. Thus, when the start/end pointer is set to the register 3, the setting can be done by using a conventional column address line, the column decoder 1, and requires no new constitution. Also, since the setting is performed by two cycles, cycle 1 and 2, a high speed setting is possible.
