Title: Moving handrail device for man conveyor
Inventor: KAWASAKI ATSUSHI
IPC: B66B23/24
Filed: 1997-05-19
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of a handrail release without increasing travel resistance during a normal operation by providing multiple projections having an acute angle cross section and facing the inner face of a moving handrail on the back face of a handrail guide. SOLUTION: Multiple projections 21a extended in the longitudinal direction and having an acute angle cross section are provided on the back face of a handrail guide 21 symmetrically on the right and left. During a normal operation, a moving handrail 5 is moved along the handrail guide 21 in contact with only the upper face of the handrail guide 21, and the travel resistance is not increased by the projections 21a provided on the back face of the handrail guide 21. When external force is applied to the moving handrail 5 to remove a foreign matter entering between a holding frame 2 and the moving handrail 5, the tip section (acute angle section) of the projection 21a bites into an inner face cotton fabric layer, and a handrail release is prevented.

Title: Production of single crystal
Inventor: HORIKAWA JIYUNICHI
IPC: C30B11/00
Filed: 1982-07-23
Abstract: PURPOSE:To obtain a large-sized single crystal having uniform compsn. by putting a raw material for a crystal into a crucible, and melting the entire part thereof then solidifying the same from the top to bottom end of the crucible. CONSTITUTION:A raw material 2 for a crystal is packed in a crucible 1 and is melted, whereafter a seed crystal 4 having an optional crystal orientation is put in the part 3 at the top end of the crucible. The crucible 1 is gradually heated in an electric furnace 5 which provides a suitable temp. gradient to allow a single crystal to grow from the seed crystal 4 at the top end of the crucible toward the bottom end. The bottom end 5 of the crucible 1 is made flat to permit easy supporting at the bottom. The molten raw material solidifies from the top end according to the above-mentioned method; therefore, the part at the top end plays the role of a cover, and the evaporation of the element is extremely minimized. The reduced time when the part at the top end of the crucible is exposed to high temp. contributes also to the prevention in the evaporation of the element. The single crystal having a uniform compsn. is thus produced.

Title: Driving controller for shutter blade
Inventor: KONO TAKANORI
IPC: G03B9/08
Filed: 1994-06-10
Abstract: PURPOSE:To stably keep the moving speed of a shutter blade in the case of moving in an opening direction. CONSTITUTION:Plural slits 28 are arrayed along the moving direction of the shutter blade 24 at a specified pitch on the blade 24. A timing pulse whose pulse interval corresponds to the moving speed of the shutter blade 24 is obtained from a photointerruptor 30. A pulse interval comparing circuit 38 measures the pulse interval of the timing pulse, and compares it with referential pulse interval stored in a referential pulse interval storing memory 42. A speed correcting signal DELTARN corresponding to the difference is converted to a driving correcting signal DELTAN by a driving current correcting circuit 39. The driving correcting signal DELTAVN is added to the driving signal V0 outputted from a driving current setting circuit 40, and inputted to a motor driver 36. The motor driver 36 supplies a driving current corresponding to 'V0+DELTAVN' to the motor 35. The signal DELTAVN corresponding to the moving speed of the shutter blade 24 is fed back to the motor driver 36 so as to stably keep the moving speed of the shutter blade 24.

Filed: 1992-05-22
Abstract: PURPOSE:To provide a constant current output circuit prevented from being influenced by voltage variation in a sink output terminal and a source output terminal or temperature variation by a comparatively simple circuit constitution. CONSTITUTION:A sink output current +I flows from a terminal 41 into the constant current output circuit, the input current is divided into collector currents I61, I62, I63, which are allowed to flow into respective transistors(TRs) 61 to 63 and then combined to allow a source output current -I (=+I) to flow out to a source output terminal 42. The current I63 flowing into the TR 63 is a value obtained by dividing voltage between the base and emitter of the TR 62 by the resistance value of a resistor 72. Thereby when the TRs show ideal characteristics, the currents +I, -I are not influenced by voltage variation of the terminals 41, 42. When the resistance values of the resistors 71, 72 and an emitter area ratio between the TRs 61, 62 are selected, the temperature characteristics of the currents +I, -I are offset and the influence of temperature variation can be removed.
