Title: Semiconductor-element isolating structure and manufacture thereof
Inventor: FUKUMA MASAO
IPC: H01L21/76
Filed: 1985-05-27
Abstract: PURPOSE:To make a leaking current along the side wall of a groove sufficiently small, by providing the groove, in which an insulating material is buried, in a semiconductor substrate, providing a layer comprising a high conducting material on the inner side wall of the groove so as to hold a thin insulating film having about the thickness of a gate insulating film, and using a groove isolating method. CONSTITUTION:A groove is formed in a semiconductor substrate 1 by sputter etching and the like. Then, a thin insulating film 2 is grown on the inner wall and the entire buttom surface of the groove. Then, high-melting point metal 3 is attached on the entire surface of the substrate 1 by a CVD method. The highly conducting material 3 is made to remain only on the inner wall of the groove by a sputter etching method. An insulating material such as SiO2 is buried in the groove by the CVD method. In this structure, the high melting point metal 3 is negatively biased with respect to the substrate potential when the substrate 1 is a P type and positively biased when the substrate 1 is an N type. Then an accumulating layer 5 of carriers is formed on the outer surface of the groove. Therefore, the surface potential even at a part close to the surface on the side of the groove can be kept at a sufficiently low value. A threshold voltage, which is higher than that of an MOS FET in an ordinary active region is obtained. The leaking current between a source and a drain along the side wall of the groove is completely eliminated.

IPC: H04Q3/545
Filed: 1990-04-27
Abstract: PURPOSE:To avoid the cutting-off of a call except cutting-off object by retransmitting by returning a call cutting of report and executing call cutting off processing when the call is the same call and returning a call cutting off completing report signal without executing the call cutting off processing when it is not the same call. CONSTITUTION:The above call cutting off system consist of channel control switch modules 4 and 9 to house subscriber terminals 5 and 10 through a channel 12 and call control modules 1 and 6 which consist of central processing units 2 and 7 and inter-module signal controllers 3 and 8 to control the transmitting/receiving of a call control signal on an inter-module signal line 11. Then, when a call cutting off requiring signal is received, it is discriminated whether it is the call cutting off requirement of the same call as the call in processing or not, when it is the same call, a call cutting off report is returned and call cutting off processing is executed and when it is not the same call, a call cutting off completing report signal is returned without executing the call cutting off processing. Accordingly, the call processing task of a call cutting off requiring source can receive the call cutting off completing report signal inevitably. Thus, the cutting-off of the different call which is not a cutting off object at the retransmitting of the call cutting off requirement when it is lost is prevented.

IPC: B24B1/04
Filed: 1987-05-11
Abstract: PURPOSE:To prevent a temperature rise due to frictional heating, improve the quality of discharging chips and enable efficient machining by applying a vibration of frequency (f) and amplitude (a) to a workpiece in a machining direction, and carrying out a machining work in the condition wherein the feed speed F of a tool is so selected as to satisfy a relationship of F<aXf. CONSTITUTION:An axis-fitted grindstone 9 is used and turned in an arrow A direction. And when the grinding direction of the grindstone 9 is in an arrow B direction, an actuator in an X or Y direction operates to oscillate a vibration bed 1 and a workpiece 8 in an arrow C direction. And if the feed velocity of the grindstone 9 is taken at F, the amplitude (a) and the frequency (f) of the vibration bed 1 and the workpiece 8 are so selected as to satisfy a relation- ship of F<aXf. Then, a fine space is generated by (f) times between the grindstone 9 and the workpiece 8, and a cutting oil can be easily fed to the space between the grindstone 9 and the workpiece 8. It becomes possible, therefore, to prevent a temperature rise due to frictional heat at a machining point and discharge chips efficiently, thereby enabling the machining of the workpiece 8 with good machining efficiency.

Title: Cutoff valve
Inventor: SASAKI TOSHIKATSU
IPC: F16K17/20
Filed: 1979-09-04
Abstract: PURPOSE: To place a cutoff valve in the state of opening only when the pressure in a flow route is kept within the range set beforehand by a cam and a follower engaged in linkage.  
     CONSTITUTION: When a follower 17 is positioned on the circular-arc cam surface  of a cam 22, a valve body 4 is dispaced to the right against the spring force of a  spring 6 and separated from a valve seat 3, and a valve 5 is found in the state of  opening. When the pressure of the valve 5 on the downstream side thereof is above  the upper-limit pressure or below the lower-limit pressure, either of which is set beforehand, the follower 17 is put in the concavity of a cam 21, the valve body 4 is  seated on the valve seat 3 by the force of the spring 6, and thus the valve is found  in the state of closing. The angular displacement of the cams 21 and 22 dependent  on the pressure on the downstream side of the valve 5 is not transmitted to a  plunger 35 and thus the valve is forced into the state of closing. When the pressure  of the valve 5 on the downstream side thereof is within between the upper-limit and  lower-limit pressures, the follower 17, which is placed in the state of being put in  the concavities of the cams 21 and 25, displaces an axis 23 through rotation and  thereby the valve body 4 is separated from the valve seat 3.

Title: Organic nonlinear optical compound
Inventor: TSUNEKAWA TETSUYA
IPC: G02F1/355
Filed: 1986-05-21
Abstract: PURPOSE:To obtain a compd. having large optical nonlinearity by introducing an acceptor type substituent to the 2nd position of a pyridine ring. CONSTITUTION:The resonance effect that a conjugation system in such 6pi system as the pyridine ring provides is large. The distortion generates the pielectron cloud of the excitation state arising not from the base state but from the acceptor level and generates a large deviation in the electric charge distribution when nitrogen atoms exist in the ortho position of the acceptor type substituent. The fluctuation of the pi electrons by the perturbation of the optical electric field possessed by laser light and the optical nonlinearity possessed by the compd. increase if the dipolemoment of the excitation state increases in the above-mentioned manner. The compd. having the acceptor in the 2nd position of the pyridine ring has eventually the excellent optical nonlinearity.
