Title: Immersion cooling method of cast slab
Inventor: TAKAHASHI YUTAKA
IPC: B22D11/124
Filed: 1979-05-02
Abstract: PURPOSE: To evenly cool the continuously cast slab of high temperatures without producing any vibration and noise and make the cambers of the slab obsolete by immersing said slab into a cooling liquid and quenching by force-sputing a compressed gas from the underside of the cast slab.   
     CONSTITUTION: Industrial water 3 is filled in a water tank 1 which comprises coating reinforced concrete to provide water resistance. Compressed air 5 is spouted through the holes opened in multiplicity in the pipes 4 provided in the lower part within the water tank 1, and the continuously cast slab 2 having been heated to red hot to high temperatures is placed on bases 6. The cooling water 3 is supplied at all times and is kept overflowed from the water discharge port of the water tank 1. The compressed air 5 is spouted over the entire surface on the underside of the cast slab 2 and agitates and moves the cooling water 3, hence the steam generated from the cooling liquid below the slab 2 no longer produces any explosive sound and noise. In addition, the cooling water 3 is agitated and therefore the slab 2 is evenly cooled and the occurrence of cambers is obviated.

Title: Compound semiconductor film and manufacture thereof
Inventor: SHIBATA NORIYOSHI
IPC: C30B25/02
Filed: 1987-03-09
Abstract: PURPOSE:To control the load of an impurity into a semiconductor film by adding nitrogen as an impurity. CONSTITUTION:A compound containing a IIb group, a compound containing a VIb group and the compound of hydrocarbon containing a nitrogen element as an impurity introduced to a compound semiconductor such as amine as raw material gasses for a compound semiconductor film are induced into a reaction vessel in the vapor phase by a carrier gas (such as hydrogen gas), and a IIb-VIb compound semiconductor film is grown through a chemical vapor phase reaction. Regarding manufacture, amine is preferable as hydrocarbon including the nitrogen element as the introduced impurity, and it is desirable that an alkyl group constituting amine consists of either of a methyl, ethyl propyl, butyl or benzene group. Amine as a ring-structured molecule containing the nitrogen element can also be used besides amine having the alkyl group. Accordingly, the formation of a deep impurity level can be inhibited.

Title: Reflecting telescope
Inventor: OE ATSUSHI
IPC: G02B7/00
Filed: 1998-03-05
Abstract: PROBLEM TO BE SOLVED: To make a telescope compact and light in weight, to attain the high rigidity and low thermal expansion and to prevent the mirror shape of the primary mirror thereof from being deformed by coupling a first and a second reflection means by a supporting member so as to be opposed and arranging the supporting member at the reflection center of the first reflection means. SOLUTION: A secondary mirror 23 is fitted so as to be opposed to the primary mirror 21. Then, the central part of the mirror 21 is provided with a receiving part 24 and the supporting member 25 is fixed by being engaged with the receiving part 24. That means, the receiving part 24 is formed so as to dent by prescribed depth from a reflection surface 22, for example, in a circular recessed state whose plane shape is provided with a prescribed diameter. Besides, a prescribed-diameter through-hole 26 is formed at the bottom surface of the receiving part 24 so that light reflected on the mirror 23 is passed through the hole 26 and the image thereof is formed at a prescribed position. Thus, the occupying space of the reflecting telescope 20 is made small and the weight thereof is reduced. Besides, since the supporting member 25 is coupled to the vicinity of the center of the gravity of the reflection means, the rigidity is enhanced as a whole.

Filed: 1995-02-20
Abstract: PURPOSE: To provide an attenuator function for varying an attenuation factor at the time of strong electric field reception by providing a reception signal attenuation means for preventing the input level of a reception circuit from becoming excessive in an antenna switch. CONSTITUTION: When a reception timing comes, a microcomputer 5 turns a control switch 3 to neutral and turns OFF a PIN diode D1. Then, from the output of a level detection circuit 9, the level of reception signals leaked through the PIN diode D2 which is completely turned OFF and inputted to the reception circuit 7 is detected. Then, the reception signal level is compared with a reference value, the resistance value of a voltage controlled type variable resistor (VCR) 4 is varied corresponding to the reception signal level and the control switch 3 is switched to reception. By the constitution, the PIN diode D2 functions as an attenuation factor variable type attenuator as well, and when the reception signal level is high, by appropriately enlarging the ON impedance of the PIN diode D2, the reception signals are attenuated.

Filed: 1981-04-10
Abstract: PURPOSE:To perform welding work easily and stably without fresh setting of welding conditions in a short circuit transfer arc welding machine by regulating the current of the arc period automatically according to the feed rate of a wire thereby controlling weld heat input. CONSTITUTION:A wire electrode 7a of a wire 7 in a welding torch 9 is short- circuited to welding base metals 10, and short circuit current is flowed from a DC powr circuit 1. The leading end of the electrode 7a is burned off and an arc is generated; at the same time, the reference pulse current waveform corresponding to the feed speed of the wire is generated from a reference pulse waveform generator 23. This reference pulse current waveform and the current value signal detected with a current detector 11 are inputted to a comparator 24 which applies on and off signals to a switching element 2 when the value of the difference between these is positive and negative. The current waveform, that is, electric charge quantity, during the arc period is controlled by the feedback controlling of the current during this arc period, whereby the quantity of heat input is controlled and the welding work is accomplished stably without fresh setting of welding conditions each time.
