IPC: G01S13/46
Filed: 1983-09-20
Abstract: PURPOSE:To make it possible to detect and active target with high accuracy by enlarging the detectable range of the active target, by detecting that the target is present on a curve having two stations as focal points. CONSTITUTION:By the radio wave emitting time from a radar main station 1 and the receiving time of the radio wave reflected from a target 2, it is detected that the target is present on an oval curve having stations 1, 1a as focal points. Therefore, the detectable range of the active target of the main station 1 can be enlarged by together using the passive receiving station 1a and, when one or two of an auxiliary receiving station is used in the receiving station 1a corresponding to the presence and absence of arrival direction detecting function, target detection can be performed with high accuracy. Furthermore, the detection of an underwater target can be similarily performed by using a sonic wave.

An insulating film 150 is removed, and next a pattern 130 is removed. Heat treatment of the insulating film 150 remaining only on the opening parts is performed to flatten the surface of the insulating film 150. The semiconductor film 120 is used as an etching stopper to etch the insulating film 150, so that the insulating film 150 is made to remain inside the opening parts more shallowly than the surface of the substrate 100. Next the semiconductor film 120 is removed. Trench separation structure can be thus obtained with good reproducibility.

Title: Freezing drier
Inventor: HAINRIHI SHIYUTAINKANPU
IPC: F26B5/06
Filed: 1988-07-14
Abstract: PURPOSE: To take over a pumping work by an additional condensation surface, maintain the vacuum of a freezing drying chamber irrespective of an operating medium and prevent the loss of a batch of products by providing the additional condensation surface in an apparatus and connecting the condensation surface to a storage container having a low boiling point refrigerant through a valve. CONSTITUTION: Products are housed and frozen in a chamber 1. For a main drying operation, valves 15 and 17 are opened and a temperature adjusting medium flowing in a temperature adjusting circuit 3 is heated. The chamber 1 is exhausted to have pressure of about 10<-1> mbar. A condensation surface 18 is coolded by a compression freezing machine 5. A small quantity of remaining permanent gas passes through a condenser 12 and is removed by a gas ballast pump 13. If a failure occurs, the cooling of the condensation surface 18 is cancelled. Upon this kind of failure, the pumping power of the water pump of the condenser 12 causes a valve 25 to be opened irrespective of the operating medium, so that a low boiling point refrigerant 27 enters a coil shaped pipe forming a condensation surface 23 from a lower part and evaporates therein and accordingly the condensation surface 23 is very rapidly cooled to a relatively low temperature. Thus, the generated failure can be removed.

Abstract: PURPOSE:To prevent occurrence of air-voids in the surface of a product, by setting a slit section on a sheet mainly comprising an expandable resin in order to evacuate the air inside and melt and mold the sheet in a mold. CONSTITUTION:A large-sized sheet 10 blended with an expandable material where a slit section 11, 11... retaining gaps l3 of a required size or less is formed, is charged into a recessed section 9 on a bottom force 2, and a top force 5 is joined to it. A high-frequency current is impressed for a required time on both electrode boards 6 and 7. Then, the sheet 10 is expanded and the expanded air is evacuated from the slit section 11, 11... upwards and through the clearance of the top and the bottom force. The sheet 10 is melted and a skin layer is formed on the surface abutting to the bottom force 2, so that a cooled and cured decorative molding is completed. After evacuating the air, the slit section 11 disappears as a synthetic resin melts. Consequently no void caused by an expanded air remains on the surface of the obtained decorative molding and the surface is kept clean.

Title: Light emitting diode
Inventor: SHIMADA MASARU
IPC: H01L33/30
Filed: 1987-07-13
Abstract: PURPOSE:To obtain a light emitting diode which has an improved light emitting efficiency in a high current region and an improved reliability by limiting a light emitting region without using an SiO2 film. CONSTITUTION:When a current is made to flow from a p-type electrode 16 to an n-type electrode 17, as the conductivity type of a current limiting layer 18 is an n-type, the current flows only in a p-type Zn diffused region 21 formed by diffusing Zn. The diameter of the Zn diffused region is about 30mum but the diameter of a light emitting region 22 becomes about 35mum due to the spread of the current and the like. Therefore, the current can be limited and the light emitting region 22 can be limited within a small region without forming an SiO2 film. With this constitution, the degradation of a light emitting efficiency at the time of high current injection can be reduced and a reliability as a device can be improved.

Abstract: PROBLEM TO BE SOLVED: To make it easy to insert and draw out a printed wiring board. SOLUTION: Each pair of contacts 1 is curved so that their upper ends approach each other, and a main gap for inserting a printed wiring board 8 and an auxiliary gap are formed in such a way as to be vertically aligned. An insulative rectangular rod-shaped working tool 2 is provided across the opposite lines of contacts 1 in such a way as to be capable of back-andforth parallel movement along the longitudinal direction of the contacts 1. This back- and-forth parallel movement allows the tool 2 to be fitted between the auxiliary gaps in the pairs of contacts 1 or released to widen or narrow the main gaps, Control levers 3 that rotate about shafts 4 are placed to correspond to the right and left ends of the working tool 2 and are turned by the short sides of an L shape to cause the ends of the long sides of the L shape to abut to the lower surface of the end of the working tool 2.  Prior to insertion and during extraction, the working tool 2 is put into upward parallel movement via the control levers 3 and fitted into the auxiliary gaps in the contacts 1 to widen the main gaps so that resisting forces during insertion and extraction are set to zero.
