Title: Continuous sheet transfer method of printer
Inventor: TERANISHI SHUNPEI
IPC: B41J11/42
Filed: 1991-02-20
Abstract: PURPOSE:To shorten intervals between sheet feeds at the time of continuous transfer of sheets by continuously performing a process wherein a sheet is fed to a printing position or fed thereto in advance and a process for control of the sheet from the change of lines to the delivery of the sheet. CONSTITUTION:A motor 10 is reversely driven to feed a sheet from a hopper 3 through a sheet feed roller 5 and a separation roller 6, then to an inserter roller 7. When the sheet 14 reaches the roller 7, a manual insertion detecting sensor 12 detects the leading end of the sheet to turn the motor 10 in a normal direction, thereby starting an advance feed control. When a position where the printing of the sheet starts has come just under a printing head 2, the advance control is finished, while line feed of the sheet 14 by the roller 7 is performed until the leading end of the sheet leaves the roller 7. As soon as the tailing end of the sheet 14 passes just under the head 2, a delivery action by a delivery roller 9 is started and then finished when the trailing end of the sheet 14 has left the roller 9 and a motor 11 is caused to rotate in a normal direction.

Title: Electric wire coiling device
Inventor: MAKINO TSUTOMU
IPC: B65H54/04
Filed: 1982-02-23
Abstract: PURPOSE:To obtain a uniform winding in layers by installing, in such a manner as capable of rising and sinking freely a core for insertion of the wind up drum at a framing, mounted on the base with possibility of vertical motion as well as rotation, and by allowing the wind up drum to rotate and rise/sink so that the tension of the wire is held always with a certain constant value. CONSTITUTION:For wind up of a wire 9, first wind up drum 2 is placed on a roll 18 and then a core 22 is set in this wind up drum 2 by lifting a cylinder 3, whereafter the end of the wire 9 is fastened to the wind up drum 2. Then a motor 11 is started to rotate a rotor 8 through a powder clutch 10, and the wire 9 is wound by rotating the wind up drum 2 through a rotary drum 5. When the tension of the wire 9 attains a certain specified value, a tension controller 31 shall put the powder clutch 10 in action so as to transmit power to the rotary drum 5 in a specified amount. When winding-up is completed, a vertical motion controller 30 shall invert the rotational direction of the motor 14 to let the cylinder 3 fall with the aid of a jack 13. Then the wind up drum 2 is sent forward to the next process.

Title: Shield boring machine and method using the shield boring machine
Inventor: INO TOSHIMI
IPC: E21D11/00
Filed: 1999-02-04
Abstract: PROBLEM TO BE SOLVED: To impart no adverse effect to a natural ground even in a shield tunneling in a shallow overburden by providing a slidable plate which is relatively transferable against the shield machine body at the outer peripheral face of the body and is equipped with a drive means. SOLUTION: A plurality of slidable roof plates 15 are put on almost all over the whole face of the upper surface of a skin plate 13. A connecting tool 25 connecting the slidable roof plate 15 and the cylinder rod 27a of a hydraulic cylinder 27 is fitted to a thick part 15a formed at the front end. The slide roof plate 15 becomes transferable back and forth within a range of stroke by extending or contracting the cylinder rod 27a of the hydraulic cylinder 27 fixed to the machine inside. When the cylinder rod 27a is extended to make the hydraulic cylinder 27 free to start boring, the slide roof plate 15 is subjected to a friction force reverse to the excavation direction from the natural ground, but as it is larger than a friction force in the boring direction exserted by the skin plate 13, the slide roof plate is relatively transferred backward against the boring machine 1.  Therefore, any force in the boring direction does not act on the natural ground during the boring work. Hence, no adverse effect arises on the natural ground.

Filed: 1981-02-25
Abstract: PURPOSE: To increase the linear range of mutual conductance by connecting the corresponding-side collectors of transistors (TR) in a differential couple to a common load resistance, and applying different bias voltages to the other-side bases of the TRs.  
     CONSTITUTION: Transistors TRs T 1  and T 2 , and T 3  and T 4  form differential couples. The TRs T 2  and T 4  use a resistance Ra as a common collector load, and the TRs T 1  and T 3  use a resistance Rb as a common collector load. The base of the TRs T 2  and T 4  are connected in common and biased by a voltage Vb 2 . The bases of the TRs T 1  and T 3  are independent of each other, and biased by a voltage Vb 1  and a voltage Vb 1 +ΔVb. Consequently, the range of mutual conductance which is considered to be linear is made about three times as wide as that of a single differential couple.

IPC: E04B1/41
Filed: 1996-02-15
Abstract: PROBLEM TO BE SOLVED: To arrange various members and increase the fitting strength, by embedding an insert element in a base material and coaxially arranging an insertion hole for a fixing tool against a fixing hole, from the surface of the base material to the fixing hole of the insert element. SOLUTION: An insert element 1 fitted to the front end of a guide rod is inserted in a hole of a mold and a solidifying filler is charged in the hole and cured therein to form the element 1 in a base material 5. These are removed from the mold and the guide rod is removed to form a corrosion-proof insert tool body 6 and fix it in an existing concrete structure with an adhesive. In this case, when the element body is made of a ceramic, the pulling strength and the shearing force of the fixing hole 1a are increased. And when the element 1 is fixed to the base material 5 with an adhesive and an epoxy resin having a larger strength than concrete is used for the solidifying filler, an inexpensive, light-weight, and larger fitting strength element body can be obtained and if a collar is set on the guide rod, the element can be positioned when the guide rod is inserted in the hole.

IPC: B29C65/04
Filed: 1980-03-05
Abstract: PURPOSE:To mould easily a cover pad for sheet on which monolithich undulated patters are formed, by stacking the outer skin on the pads with the adhesives applied with a desired pattern, pressing with the flat plate mold, applying highfrequency heating and fixing partially by the adhesives. CONSTITUTION:As shown in the illustration (a), backlining material 10 and pads 4 and outer skin 3 are stacked successively between an upper mold 7 and a lower mold 9 with a silicone mold 8 thereon. The pad 4 is preliminerily impregnated with the heat-sensitive adhesives 11 with a desired pattern. Then the outer skin 3, pad 4 and backlining material 10 are pressed with high-frequency heating applied. With such an arrangement, because the shaping of undulated patterns are done not by molding but by the adhesives 11, no locally concentrated forces are applied to the atacked body at the time of pressing, resulting in a high quality cover pad for sheet with sufficient undulations thereon as desired.

Title: Developing device
Inventor: KOBU MAKOTO
IPC: G03G15/08
Filed: 1990-02-07
Abstract: PURPOSE:To sufficiently electrostatically charge, to visualize an electrostatic latent image and to improve the quality of the image by setting a space between an electrode plate and a latent image carrier so as to expand its width at the upstream side in the moving direction of a latent image carrier. CONSTITUTION:The space between the electrode plate 8 and the photosensitive body 1 is set so as to expand its width at the upstream side in the moving direction of the photosensitive body 1. Following the movement of the sensitized body 1, an air current is generated and the toner is carried thereon to be introduced into the space between the electrode plate 8 and the sensitized body 1. In such a case, assuming that an electric field is formed in a direction that charged particles Q are attracted to an electrode plate B, these charged particles Q receive centrifugal force Fc in the normal direction of the line of electric force. Furthermore, the charged particles Q receive force Fg attracting them to this electrode plate B in the tangent direction of the line of this electric force. Hence, the charged particles Q are moved toward a wider opening between both electrode plates by the combined force. Thus, such images where surface staining is eliminated and fine lines and edge parts are excellently shown can be obtained.
