Title: Picture binarizing circuit
Inventor: IMAMURA KAZUO
IPC: G06K9/40
Filed: 1984-07-03
Abstract: PURPOSE:To minimize influences of the variance of the luminance level of the whole of a picture and eliminate influences of a background noise, a false light source, etc. by designating the range of significant signal as the range of the luminance order in one field of an input picture. CONSTITUTION:A video luminance signal is inputted to a RAM10 through a sampling circuit 2, an B-bit quantizing circuit 3, and a data selector 9, and a luminance histogram for one field is generated on the RAM10. An adding circuit 15 outputs the address output and the addition output to a significance discriminating circuit 18, and this significance discriminating circuit 18 compares the range of the luminance order of the significant signal with the output of the adding circuit and outputs the address output of the adding circuit 15 to a miximum value and minimum value detecting circuit 21 as the luminance of the significant signal. A binarizing circuit 24 uses the output of this maximum value and minimum value detecting circuit 21 to binarize the digital video luminance signal.

Title: Optical information recording and reproducing device
Inventor: SUZUKI YASUO
IPC: G11B7/12
Filed: 1984-07-03
Abstract: PURPOSE:To attain tracking at a high response speed with simple constitution without using any mechanically mobile part, by using an acoustic/optical deflector for tracking. CONSTITUTION:An acoustic/optical deflector 24 is used in place of a normal tracking mirror. This deflector 24 is produced by attaching a transducer 34 such as a comb-shaped electrode, etc. to the side face of an acoustic/optical medium 37 containing an LiNbO3 piezoelectric crystal, etc. When a high frequency signal 35 is applied to the transducer 34, the incident light 30 is diffracted by ultrasonic traveling wave 36 and delivered in the form of a diffracted beam 32. This beam 32 is varied by the length of the wave 36 with an extremely high response speed, i.e., several musec. Thus it is possible to deflect quickly the light 30 in an optional direction within a prescribed range by changing the frequency of the signal that is supplied to the transducer 34.

Title: Method and apparatus for improving ground
Inventor: OZAWA HIDEO
IPC: E02D3/12
Filed: 1984-07-05
Abstract: PURPOSE:To prevent the lowering of the strength of the ground by a method in which the ground is excavated by an excavator being turned at low speed, and a soil stabilizer is injected into the excavated soil and mixed with the excavated soil by a stirrer being turned at high speed. CONSTITUTION:A driver is operated to turn the excavating shaft 10 at low speeds, and the ground is excavated by the blade 14 of an excavator 16. As the excavator 16 is lowered, the stirring blade 24 being turned at high speeds is also lowered, and a soil stabilizer is injected from a nozzle 26 into the excavated soil and mixed with the excavated soil with stirring. The driver can thus be used with small output since it is turned at low speed, and the miniaturization and weight reduction of the device can be attained. Since the stirring blade 24 is turned at high speed, the leak of soil stabilizer to the outside and the lowering of the strength of the ground after being improved can be prevented.

Abstract: PURPOSE: To improve productivity by separating a formed mold injecting molding sand from a de clamping mechanism, firing at a first firing position and setting the other forming mold at a second firing position into a die clamping mechanism to execute the injection into the other forming mold during firing. CONSTITUTION: When the de clamping of an A die completes, an injecting tank 32x is shifted to the A die direction with a traversing cylinder 34y and a nozzle 32n is connected with an opening hole of the A die to inject the molding sand and the nozzle is returned back to the original position. The A die is shifted to a firing part 40 direction by working the drawing-in mechanism 50 and fired at the first firing position C with a first roller conveyor 46a. A B die positioned at the second firing position D is shifted to a lower die supporting mechanism 22 with a second roller conveyor 46a and the drawing-in mechanism and the opening between an upper die and the lower die, is executed to take out a sand mold as the molding for product by pushing up with an ejecting pin. The B die is clamped as the same way as the A die to execute the injection of the molding sand.  Since the injection of the molding sand into the B die is executed during firing the A die in such a way, the productivity can be improved.

Title: Enclosing and molding method for semiconductor element
Inventor: SOKABE MASATERU
IPC: B29C45/26
Filed: 1982-08-11
Abstract: PURPOSE:To reduce materials discarded as a curl and a runner, to shorten curing time and to promote the automation of molding by combining the runner section of a die for molding and a pot section, charging the material heated and melted, and pressing and filling the material to a cavity by using a plunger taking the shape of a runner. CONSTITUTION:Since the runners 4 are used directly as pots, the material passes directly through a gate without passing through the runners 4 and is filled to the cavities 5, and a time when the runners 4 pass is shortened. Excellent filling capability is obtained even in a material of a short flow and a material of quick curability because there is no reaction on passage through the runners, a molding cycle is shortened largely while the thickness of the runners 4 can be thinned by using a proper quantity of the material, and the material can be reduced largely because there is no curl, also. That is, the material preheated and weighted by an in-line screw can be filled to the pot sections in the same manner as injection molding, unlike an independent multi-pot. The increase of the material discarded can be prevented by thinning the thickness of the material by a transfer by the plunger 2 at that time even when an area of projection is taken largely in order to facilitate injection in the runners.
