Patent JP-H1130311-A (JP)
Title: Gear assembly
Inventor: SHOOK PATRICK J
IPC: F16H57/022
Filed: 1998-05-07
Abstract: PROBLEM TO BE SOLVED: To reduce the noise of a gear train and bear a high load by establishing a first meshing between a first gear and a second gear which is a seizer gear form and that the installation position of a third gear formes a second meshing with the second gear. SOLUTION: By that the thickness of the circumferential direction of a tooth 66 is smaller in comparison with a tooth 76, it is prevented that the load of the gear 66 exceeds the load given by a compression spring. The tooth 76 bears a load exceeding the spring load in comparison with this. A reverse direction bending load based on the random size difference of respective members of tooth pairs having the same circumferential direction thickness is usually reduced by that the load of the tooth 66 is limited to a spring bias force. The tooth surface of the wider side of each tooth 76 is selected so as to bear a high drive load exceeding the spring bias force.  The increase of an entire width in the gear 50 is usually smaller than the increase amount of a width required to bear the reverse direction bending load by the seizer gear having the same nominal circumferential direction thickness in every teeth.

Title: Toner replenishing device
Inventor: TAKAHARA KENJI
IPC: G03G15/08
Filed: 1979-09-27
Abstract: PURPOSE:To make replenishing of the toner easy by providing a cartridge which is closed at both ends, has an opening on the side face and contains the toner therein, and a cartridge containing part which can contain this turnably and has an opening corresponding to the opening of the cartridge in a predetermined position. CONSTITUTION:A toner cartridge 1 is closed at both ends, and has an opening 2 at the side face, which opening 2 is held sealed by a filmlike sealing material 4 in the state that the toner is held packed in said cartridge. The coupling pins 11a, 11b of a turning member 9 are inserted into the coupling holes 5a, 5b of the cartridge, and by holding the cartridge with hand in such a manner that the opening 2 faces upward, the sealing material 4 is stripped and the cartridge 1 is inserted into the cylindrical member 6a of a cartridge containing part 6. In this case, if the pin 10 of the turning member 9 is led into a guide groove 8 and the member is rotated in the arrow direction until the pin 10 abuts on the end 8a of the guide groove 8, the toner falls downward by passing through the openings 2 and 7. Hence, the toner is easily replenished without scattering.

Title: Planar shape measuring apparatus
Inventor: WAGAI MITSUO
IPC: G01B11/24
Filed: 1984-06-18
Abstract: PURPOSE:To permit high-speed scanning and enable highly accurate measurement of a planar shape, by disposing parabolic mirrors on the optical axis between a polygon mirror and an object of measurement, the parabolic mirrors being set so that the incident light thereto has angular changes in X- and Y-directions, and parallel reflected rays are obtained at all times. CONSTITUTION:The light radiated from a light source 1 is passed through a half-nirror 8 and successively reflected by an X-direction polygon mirror 2, a Y-direction polygon mirror 3, an X-direction parabolic mirror 4, a plane mirror 6 and a Y-direction parabolic mirror 5 to irradiate an object 10 of measurement. The light reflected by the object 10 travels backward along the above-described path and is reflected by the mirror 8 to reach a photodetector 7 where measurement is effected. The axes of rotation of the mirrors 2, 3 extend parallel to their respective orthotomic surfaces, and the mirror 3 rotates at lower speed than the mirror 2. Accordingly, the incident light to the mirror 4 has angular changes in the X- and Y-directions in response to the rotation of the mirrors 2, 3. Therefore, the respective positions of the mirrors 4, 5 and their parabolic configurations are set so that the incident light thereto enters from the focal point at all times, and the object 10 is irradiated with parallel rays, whereby it is possible to obtain an image without any distortion, and highly accurate measurement of a planar shape can be effected.

Title: Semiconductor memory device
Inventor: SASAKI ISAO
IPC: G11C11/412
Filed: 1979-09-28
Abstract: PURPOSE:To reduce the current consumption and occupied area, by using a transfer gate MOSFET of different conduction type as driving MOSFET, for a given area at the same time. CONSTITUTION:Ion injection is being made so that the threshold voltage value specified is given to transfer gate P type MOSFETQ1, Q2 and driving N type MOSFETQ3, Q4. Thus, when a voltage between the gate and the source is zero, the current between the drain and the source is greater for FETQ1, Q2 than FETQ3, Q4, and the increment of the gate voltage required to change one digit of the current between the drain and the source at the gate voltage less than the threshold value is greater for FETQ1, Q2 than FETQ3, Q4. Further, FETQ1, Q2 are operated at the gate current region at threshold value or less for load at the same time. Accordingly, the current consumption is lowered for the memory unit in comparison with use of a high resistance and the occupied area is decreased.

Title: Rinsing liquid for chemical amplification type resist
Inventor: SAITO MASAO
IPC: G03F7/32
Filed: 1989-05-18
Abstract: PURPOSE:To suppress the generation of the corrosion (after-corrosion) of aluminum wirings disposed on a substrate by incorporating a lanthanide porphyrin complex having polar groups into the above liquid. CONSTITUTION:The lanthanide porphyrin complex contg. the polar groups is incorporated into the rinsing liquid used for a chemical amplification type resist contg. an acid generating agent which generates halogen acid when irradi ated with light. The halogen ions of the halogen acid generated from the acid generating agent of the chemical amplification type resist by an exposing processing are, therefore, captured by the lanthanide porphyrin complex, by which the excess halogen ions are removed from, for example, the aluminum wirings, etc. The corrosion of the aluminum wirings, etc., are prevented in this way.

Abstract: PURPOSE:To speed operation and to save power consumption by providing a half- mirror in an optical path from a projection lens to a photoreceptor, a light source branched by the half-mirror, and a mask which is arranged behind the half-mirror and compensates light-quantity loss distribution. CONSTITUTION:Light from a fixed light source 10 is reflected by a reflector 11, etc., and transmitted through a half-mirror 9 to be projected inversely in a slit shape on an original surface 2 by a projection lens 5 through the 2nd scanning mirror 4 and 1st scanning mirror 3. In this case, the light from the light source 10 has the loss of the quantity of light raised to the cos 4th power rule but a mask 13 having a shape transmitting the light more at the center part in the lengthwise direction than at the circumferential part is set between the half-mirror 9 and light source 10. Consequently, the light from the light source is imaged at the iris position of a reverse projection or projection lens on an original surface to compensate the distribution of the said loss, thereby obtaining a lighting device suitable for high-speed copying operation.
