Title: Motion vector detection method
Inventor: SABURI KAZUMITSU
IPC: H04N19/51
Filed: 1995-02-27
Abstract: PURPOSE: To efficiently detect a motion vector with extremely high detection accuracy by performing block matching by a minimum detection accuracy unit in the range of peripheral ±a picture elements based on a first motion vector. CONSTITUTION: Candidate blocks 62 are set within a detection range 60 on reference pictures with the interval of α picture elements respectively in horizontal and vertical directions and the block matching of an encoding unit block 64 and all the set candidate blocks 62 is performed.

However, for the candidate block for which the matching is performed at the time of detecting the first motion vector 66, the need of performing the matching again is eliminated since judgement is already ended.

Title: Feeding device of raw material
Inventor: KOBAYASHI MASAHIKO
IPC: F27B21/10
Filed: 1983-03-10
Abstract: PURPOSE:To prevent a raw material from falling down from a grate and yet the grate from being clogged by a method wherein a lower layer is formed with granular lumps having comparatively larger diameter and an upper layer is formed with particles having comparatively smaller diameter by means of a sieving device. CONSTITUTION:Crushed lump-like raw material 5 in a feeding device 2 is cut-out by small portions by means of a cutting-out device such as roll feeder, gate or the like and falls along an inclined plane 10 in order to be supplied to a processing device 9 of crushed lump-like raw material. A grating-like sieving member 11 is mounted on the inclined plane 10. Out of the crushed lump-like raw material, particles 12 with small diameter pass through the sieving member 11 and fall down, while raw material 4 with large diameter slides on the inclined plane 10 without passing through the sieving member 11 and falls on a vacant grate 3. Because the grate 3 moves in the direction indicated with the arrow, the particles 12 with small diameter past through the sieving member 11 fall on the crushed lump-like raw material 4 with large diameter, which have fallen and been heaped up on the grate 3. Consequently, the clogging of the grate can be prevented and the reduction of cost can also be contrived.

Title: Method for deciding surface and rear side of developed film
Inventor: SETO YASUHIRO
IPC: G01N21/89
Filed: 1983-03-09
Abstract: PURPOSE:To decide the surface and the rear side of a developed film basing on a difference of a reflected light quantity of a specified wavelength by utilizing a difference of a spectral reflection factor of the surface and the rear side, and irradiating a light to at least one face of the surface or the rear side. CONSTITUTION:A light is irradiated at some inclined angle to the surface (or the rear side) of a film 1 from a light source through an optical fiber 2. Its reflected light is transmitted to a photodetector 5 through an optical fiber 4, and a light from this photodetector 5 is inputted to a comparator 7. Also, a prescribed reference value RV is inputted in advance to the comparator 7, and it is compared with a signal from a driver 6 as to its magnitude, by which a surface and rear side deciding signal SB corresponding to the surface and the rear side of a developed film is outputted. For instance, when the signal from the driver 6 becomes larger than the reference value RV, the comparator 7 outputs the surface and rear side deciding signal SB as a logic of ''1''. In this way, basing on an output of ''1'' and ''0'' of the surface and rear side deciding signal SB, whether the irradiated face of a developing film 1 is the surface or the rear side is decided automatically.

Title: Internal-combustion engine having wall face of combustion chamber applied with heat insulating material
Inventor: KISHISHITA TAKAHARU
IPC: F02F3/26
Filed: 1984-03-02
Abstract: PURPOSE:To produce an internal-combustion engine having excellent volume efficiency while maintaining the insulating effect by covering the wall face of combustion chamber with such insulating member as produced by sintering fine hollow balls with heat-resistant metal. CONSTITUTION:A galvanized layer 5 of heat-resistant metal such as nickel is provided around a hollow ball 2 which is placed in a mold of specific shape upto specific thickness and heated under high temperature. Consequently, said layer 5 will dissolve to sinter the hollow balls 2 each other to produce a sintered metal layer 3. Then a tight coating layer 4 is provided on the surface of said insulating member 1, which is jointed through a jointing material layer 7 onto the top face of a piston 6. Consequently, the insulating member 1 is provided with excellent insulation performance because of the hollow balls 2 and low heating storage capacity because of thin sintered metal layer 3. Since the heat transmission from the insulating member 1 to the intake air is low, the cycle efficiency and the volume efficiency can be improved.

Title: B-class amplifying circuit
Inventor: SAKAI KAZUMASA
IPC: H03F3/30
Filed: 1979-03-30
Abstract: PURPOSE:To improve the switching distortion by avoiding the cut-off state for the output transistor. CONSTITUTION:In case the input signal voltage with the potential increasing at point A is applied, the base current of driving transistor 3 increases. And the increased amount of the base current of output transistor 1 is branched off to resistances 9 and 31 from the emitter of transistor 3. Here the voltage drop of resistance  9 increases, and the potential difference decreases between points B and C. However, no cut-off state is caused since the base current of driving transistor 4 is  determined by resistances 32 and 9. Also output transistor 2 has no cut-off state. In  the same way, no cut-off state is given to transistors 3 and 1 even though the input signal voltage may change and the input signal may be applied in the direction  where the potential lowers at point B.

Abstract: PURPOSE:To prevent a noise from being detected and to read out a mark by high precision by providing a differentiation circuit, a comparison circuit, a zero point detection circuit, a window circuit and an AND circuit, and detecting a regenerated signal provided that its differentiated signal is larger than a prescribed value. CONSTITUTION:A photoelectronic element 1 outputs a regenerated analog signal SA, which is differentiated by a differentiation circuit 2, and becomes the differentiated signal SB. The signal SB is inputted to the zero point detection circuit 3, and is compared with a zero level signal V0, and besides, the signal SB is inputted to the comparison circuit 4, and is compared with a reference signal Vth. When both the levels of the signal SB and the signal V0 coincide with each other, a pulse P1 is outputted as being synchronized, and is inputted to the AND circuit 5. On the other hand, when both the levels of the signal SB and the signal Vth coincide with each other, the circuit 4 outputs the pulse P2, and inputs it to the window circuit 6. The circuit 6 generates the pulse P3 as synchronizing with the rise-up of the pulse P2, and inputs it to the circuit 5. When both the pulses P1 and P3 are inputted, the circuit 5 outputs the pulse P4. The pulse the circuit 5 outputs detects always the position of the center of the mask, and detection precision can be improved.
