Title: Winding method for yarn
Inventor: YAMAMOTO SHIGERU
IPC: B65H54/32
Filed: 1981-07-22
Abstract: PURPOSE:To substantially uniform the tension exerted on a yarn at the time of winding  and make constant the wound tightness of the yarn, by a method wherein the pulsation in traverse speed is synchronized with the pulsation in traverse width, the time of  the maximum speed is made to coincide with the time of the minimum width, and the  time of the minimum speed is made to coincide with the time of the maximum width. CONSTITUTION:A traverse guide 28 is reciprocated by a rotated cylindrical cam 23, and  the yarn is wound around a bobbin 30 while traversing by the guide 28. In this case, a  driving motor 21 for the cam 23 and a motor 34 for changing the traverse width of the  guide 28 are drive-controlled by a controller 41 so that the pulsation in the traverse  speed of a guide 28 is synchronized with the pulsation in the traverse width of the  guide 28. The time of the maximum traverse speed is made to coincide with the time  of the minimum traverse width, while the time of the minimum traverse speed is made to coincide with the time of the maximum traverse width, and the rate of change in  the traverse width is increased as the traverse width changes from the maximum value  to the minimum value. Accordingly, the tension exerted on the yarn at the time of  winding is made to be substantially uniform, hence the wound tightness of the yarn is  made uniform.

Filed: 1981-07-21
Abstract: PURPOSE:To make the extension of copying paper due to moisture absorption at the center part different from that at end parts, and to prevent the copying paper from being crinkled, by forming the lengthwise sectional shape of at least one of a couple of rollers of the fixing device of an electrophotographic copying machine in hyperbolas approximate to a straight line. CONSTITUTION:At least one fixing roller R of a couple of fixing roller of an electrophotographic copying machine has larger diameters at end parts than at the center part C, and its lengthwise sectional shape has a slope like a straight line approximate to hypebolas. Namely, the slope is shown by a straight line l1 from the left-side end part E of the roller R to a conversion point P1, a straight line l2 from the P1 to the conversion part P2 of the roller center part C, a straight line l3 from the point P2 to a right conversion point P3, and a straight line l4 from the conversion point P3 to the right end. Thus, the end part of copying paper extends more than the center part at high humidity, so a feed speed is decreased gradually toward the end parts of the roller R to prevent the generation of crinkles due to irregular extension without reference to the size of copying paper width, thereby manufacturing the roller easily without any trouble in forming accurate hyperbolas.

Title: Manufacture of amorphous silicon photosensitive material
Inventor: KATOU KAZUHISA
IPC: G03G5/082
Filed: 1983-06-28
Abstract: PURPOSE:To retain a sufficient mirror state on the surface of a photosensitive material by polishing the surface of an amorphous silicon layer formed on a substrate to obtain a specified smooth surface. CONSTITUTION:The surface of an amorphous silicon material is polished by the buffing method or rotational or fixed roll method, etc. using an abrasive obtained by dispersing a fine powder, such as Al2O3, SiO2 or SiC, into a chemical composite to obtain a surface roughness of <=0.1, preferably, <=0.01mum. Selection of such surface roughness is important for image formation to control diffusion of light and to utilize the high sensitivity to light in the region from the visible wavelength to 830nm typical of the amorphous silicon photosensitive material. As a result, since the surface of the photosensitive material becomes substantially and apparently smooth, and resistant to abrasion due to a blade, the obtained amorphous electrophotographic sensitivematerial can form a superior image.

Abstract: PURPOSE:To reduce a through-current by inputting respectively an inverting signal of nearly the same phase to a base of a bipolar transistor (TR) and a gate of a field effect TR so as to transmit a signal in high speed and with low power consumption thereby selecting properly a resistance value. CONSTITUTION:When a signal phi enters the 1st input terminal 5, an inverting signal -phi being nearly the same phase as the phi enters the 2nd input terminal 6. For example, when the phi is at ''1'' level for example, the -phi is at ''0'' level and when the phi changes from ''1'' level to ''0'' level, the -phi changes from ''0'' level to ''1'' level. That is, when this circuit is connected to a CMOS load, an NPN TR202 acts like charging a load capacitance and an NMOS plays a role of extracting stored charge. When the load is assumed to be a conventional CMOS gate, the capacitance is 10pF-20pF with a wiring capacitance and the load is charged in high speed because the NPN TR202 having a high current amplification factor of 50-200 is employed.

IPC: B60R22/24
Filed: 1982-07-03
Abstract: PURPOSE:To enhace the supporting rigidity of a belt anchor, by forming a through-hole in the front edge of an outer pillar in a position corresponding to an engaging hole of a belt anchor catcher, and as well by projecting the front end part of a belt anchor catcher from the through-hole. CONSTITUTION:A through-hole 13 slightly larger than the front end part of the belt anchor catcher 9 is formed in he front edge of a outer piller in the vicinity of an engaging part 7C with respect to an inner pillar 7B, corresponding to a catcher engaging hole 4a formed in a belt anchor 4. Further, the front end part of the belt anchor catcher 9 is projected from the through-hole 13 and is received in the above-mentioned catcher engaging hole 4a. Accordingly, a pillar reinforcement 8 tends to deform in the direction of input when the belt anchor catcher 9 is applied with load. However, at this stage, the above-mentioned load is sufficiently borne since the front end part of the catcher 9 is engaged with the edge of the through-hole 13 to bear the load with the entire pillar 7 and as well the rigidity of the pillar may be ensured due to the small through-hole 13.

IPC: H04L12/28
Filed: 1992-05-08
Abstract: PURPOSE:To prevent interference to another communication through the transmission of a message whose reception is disable in the label multiplex communication of connection-less type. CONSTITUTION:Every time a message is received, whether or not a multiple speed of a message fed to the same destination as the former message exceeds a permissible reception speed of the destination is discriminated by a speed discrimination DA translation section 34. When the excess is discriminated by the discrimination processing, the translation processing of a destination address DA is inhibited. Thus, since no new header information is fed to a header conversion section 33, the received message is aborted. As a result, the message is interleaved from a multiplex signal and the multiple speed is limited within the allowable reception speed.
