Title: Interference detector of angular grinding machine
Inventor: MUNEKATA KENICHI
IPC: G05B19/4061
Filed: 1980-08-20
Abstract: PURPOSE:To prevent an interference between a grinding wheel and a head stock, and also to place a working surface at a position which is easy to work, by operating a distance between the working surface and the head stock, from a position of the grinding wheel working surface and a position of the work table. CONSTITUTION:A work table 10 moves in the parallel direction with a work axis Ow. A grinding wheel G moves along a travel 13 crossing at an acute angle with the work axis. Ow. When working is started, a reference and Sr of a work W is placed at an intersection point of the travel 13 and the work axis Ow. For instance, when a distance between a working surface Gb of the grinding wheel G and the work axis Ow is made ABSX, and a distance between the reference end Sr and the front 11a of the head stock is made La, a distance CA0 between the working surface Ga of the grinding wheel G and the front 11a of the head stock can be calculated. Accordingly, a distance CA between the head stock 10 and the working surface Ga is derived. In this way, the movement is limited so that the distance CA is kept above a tolerance value.

Title: Mis transistor and manufacture of the same
Inventor: SAKURAI JUNJI
IPC: H01L29/786
Filed: 1986-05-19
Abstract: PURPOSE:To enhance a punch-through withstand voltage without lowering switching characteristic and Gm by forming a punch-through preventive layer extended up to an element separation insulation region is separation from the bottom surface of source and drain regions. CONSTITUTION:The punch-through preventive layers 8a, 9a are P<+> type, almost perpendicular at the upper end portions and are in contact with a source or drain region 3 or 4 and a gate insulation film 6. Moreover the lower end parts thereof reach an element separation and insulation film 2 under the condition that these are separated from the bottom surface of the source and drain regions 3 and 4. Therefore, a depletion layer extended from the drain region 4 can not reach the source region 3 without breaking through the punch-through preventive layers 8a, 9a. Thereby, a punch-through withstand voltage become higher than that of a transistor having the same gate length L and moreover since impurity concentration of substrate 1 is not high and the punch-through preventive layers 8a and 9a are separated form the bottom surfaces of source and drain regions 3 and 4, therefore switching characteristic and Gm are not lowered.

IPC: B04B5/08
Filed: 1979-09-12
Abstract: PURPOSE: To permit the control of the flow rate of gas circulated for raising the efficiency of separation by providing a flow path through part of lost gas alone or parts of concentrated and lost gases, drawn out of scoop pipe, are again supplied to a supply pipe for gas to be separated.  
     CONSTITUTION: The supply pipe 50 for gas to be separated is provided with the flow path 53 through which part of lost component gas is resupplied to the lost side scoop pipe 52. Since, in the usual type centrifugal separator, the pressure near the central part of rotary cylinder is very low, the pressure of the gas supply pipe is low and the pressure of the lost side scoop pipe becomes high, so that gas of a flow rate determined by the fluid conductance of the flow path 53 and the pressure of both pipes automatically flows from the lost side scoop pipe 52 into the supply pipe 50. The installation of the flow path 53 enables the efficiency of separation to be raised at small radial position at the tip of the lost side scoop pipe.
