Abstract: PURPOSE:To smoothly supply raw materials with an approximately uniform distribution by respectively and specifically disposing openings in the lower parts of an outer cylinder which is supported inclinedly by a vibrating device and an inner cylinder which is rotatably supported therein and receives the raw materials. CONSTITUTION:This supplying device 20 has double cylindrical structures consisting of the outer cylinder 21 and inner cylinder 22 having the downward slit-shaped opening 23B and longitudinal opening 24B respectively in the lower parts ans is supported with inclination from horizontal at an angle theta. The entire part of the device 20 is vibrated by the vibrating device 28 at the time of accepting the pellets 12 supplied from a hopper 10 via the opening 23A, 24A of the outer cylinder 21 and the inner cylinder 22. As a result, the pellets 12 from the opening 24A are rolled and the lower positions in the inner cylinder 22 are successively filled with these pellets and, therefore, the pellets are distributed approximately uniformly in the longitudinal direction. Next, the opening 24B aligns to the opening 23B when the inner cylinder 22 is rotated about 90 deg. and, therefore, the pellets 12 around the opening 24B fall to a lower basket by passing the opening 23B. At this time, the distribution of the pellets 12 around the opening 24B is uniform and, therefore, the falling distribution into the basket is made approximately uniform as well.

Title: Support structure of rotating shaft
Inventor: KOIZUMI YUUSUKE
IPC: B65H27/00
Filed: 1998-09-16
Abstract: PROBLEM TO BE SOLVED: To provide a support structure of a rotating shaft allowing an easy exchange of a support member for supporting a rotating shaft and capable of reducing wear of the rotating shaft. SOLUTION: A support block 42 is formed with a recessed arc surface 42C for slidably supporting a periphery of a rotating shaft 14. The arc surface 42C of the support block 42 supports the rotating shaft 14 so as to prevent flexure of the rotating shaft 14. Because the support block 42 only receives the rotating shaft 14, the rotating shaft 14 can be taken off the arc surface 42C of the support block 42 by only lifting operation of the rotating shaft 14. In that state, the support block 42 can be dismounted from a receiving stand 38 so that the support block 42 can be easily exchanged. Because the support block 42 is made of 'Duracon(R)' containing less glass fiber than 'Delrin(R)', wear of the rotating shaft 14 caused by friction between the rotating shaft 14 and the support block 42 can be reduced.

Title: Bias circuit
Inventor: YAGI SHIZUO
IPC: H03F3/45
Filed: 1987-10-19
Abstract: PURPOSE:To keep the unit gain frequency constant by impressing the reference signal of a definite frequency to the input of an operational amplifier, and comparing the signal levels of this signal and the output signal of the operational amplifier, and controlling the bias voltage of the operational amplifier so that those levels coincide with each other. CONSTITUTION:The reference signal is assumed to be of the same frequency as the desired unit gain frequency, and is inputted to the operational amplifier A1' and a detection circuit K1. The detection circuit K1 outputs the effective value of the reference signal (full line), and impresses it to the positive phase input terminal of a voltage comparator H1. On the other hand, the operational amplifier A1' amplifies the reference signal, and inputs the amplified signal to the detection circuit K2. The detection circuit K2 operates in the same way as the detection circuit k1, and outputs the effective value of the output signal of agamma operational amplifier A1', and impresses it to the opposite phase input terminal of the voltage comparator H1. The voltage comparator H1 compares both, and outputs potential difference information, and controls biases of the operational amplifiers A1' and A1 by the signal that this output is smoothed, so as to make the unit gain frequencies of the operational amplifiers A1', A1 coincide with the frequency of the reference signal.

Filed: 1987-10-19
Abstract: PURPOSE:To prevent the crystallization of an amorphous film due to a temperature rise in heating, by determining a crystallization temperature of a film resistor to be a predetermined temperature in a thermal head. CONSTITUTION:A heating resistor film 11 is formed on an insulating substrate 11, thereon a first electrode 12 and a second electrode 13 are formed, and a heating part 15 is formed by etching.

Moreover, an ununiformity of a temperature and an expansion amount in heating due to a phase separation is eliminated, and the heating resistor 11 has a long life. The thermal head heating resistor is considered to heat up to the order of 300 deg.C in an actual printing state in printing characters, images, etc. Therefore, a crystallization temperature required to keep the amorphous phase stable without crystallization in a repeatedly heat state is considered to be the order of 500 deg.C.

Title: Manufacture of laminated body of piezoelectric element
Inventor: KATSUMATA TAKAO
IPC: H01L41/39
Filed: 1992-09-30
Abstract: PURPOSE:To prevent the destruction of a laminated piezoelectric element at the time of heating the element by heating the element to a temperature higher than the softening starting temperature of the element. CONSTITUTION:When a piezoelectric element 1 is heated to a temperature higher the softening starting temperature of the element 1, not only the external surface but also the inside of the element are sufficiently softened and the element becomes deformable. Since the softened element 1 is pressurized by means of a pressurizing piston 4, the element 1 is deformed and the surface of each constituent layer of the element 1 comes into close contact with another. When the element 1 is sintered, the particles on the surfaces of the materials to be stuck to each other move and, as a result, the materials are stuck to each other, because the gap between both materials is reduced. Therefore, a firmly laminated body of a piezoelectric element can be formed.

Title: Edge detection for light transmitting material
Inventor: KAWAHARA MASAAKI
IPC: G03F1/68
Filed: 1990-09-28
Abstract: PURPOSE:To improve the detecting accuracy of an edge by casting light on the surface of a light transmitting material at an acute angle, comparing the light with light which is cast at a vertical angle and detecting the edge of the light transmitting material based on the attenuation of the amount of the received light in a photodetector due to the increase in the light path. CONSTITUTION:The incident light 7 from a light source 6 is incident on the surface of quartz glass 5 at the incident angle of 45 degrees. The light passes through the glass 5 and reaches a photodetector 11. The light path is deviated by 0.7 mm by the refractive index of the glass 5, and the light is emitted from the glass 5. At this time, 2% of the incident light 7 is reflected from the surface of the glass 5, and the reflected light 8 is formed. In the glass 5, 6% is absorbed, and 92% of the incident light 7 becomes the transmitted light 9. Therefore, the amount of the transmitted light 9 is decreased by the amount corresponding to the increased length of the light path passing the glass 5 by about 40% in comparison with the case of the vertical incident light. The transmitted light 9 is refracted in the glass 5 and deviated downward by 0.7 mm. Therefore, an aperture 10 which restricts the light receiving plane to the minute area of 0.5 phi is provided on the entier surface of the photodetector 11. Then, the transmitted light through the glass 5 does not reach the photodetector 11 at all, and the output of a detecting device becomes zero. Thus the edge can be detected accurately.
