Title: Bobbin thread-holding device in thread cutter for sewing-machine
Inventor: DOWAKI KYOZO
IPC: D05B65/06
Filed: 1989-11-28
Abstract: PURPOSE:To surely form a seam after threads are severed, without a skip stitch because of the dislocation of the bobbin thread, by a method wherein the bobbin thread contact part of a bobbin thread-holding member is located under a movable edge and the vicinity of this bobbin thread contact part is pressed from below by a projecting part of a pressure- exerting member for holding the bobbin thread. CONSTITUTION:After a needle thread 4 and a bobbin thread 6 are severed, only the bobbin thread 6a on the side of a bobbin is held between the under surface of a movable edge 11 and a bobbin thread contact part 13a of a bobbin thread-holding member 13, and is held for the formation of the next seam. The title device is formed so that a pressure whereby the holding member 13 holds the bobbin thread 6a, is controlled by the screwing adjustment of a holding pressure-adjusting screw 20. In this way, a pressure-exerting member 16 for holding the bobbin thread is further deformed because of the elasticity of its member, and pressure-exerting force against the bobbin thread-holding member 13 is increased. For the reason, the bobbin thread-holding pressure between the under surface of the movable edge 11 and the bobbin thread-holding member 13 is made strong. After its holding pressure is properly controlled, a setting screw 19 is tightened, and thus a position of a holding pressure- adjusting member 17 is fixed and the holding pressure for the bobbin thread-holding member 13 is kept constant.

Abstract: PURPOSE: To provide a damper whose durability is improved without increasing weight and manufacturing cost. CONSTITUTION: A damper 1 is composed of a disk-shaped hub 7, annular ring- shaped elastic bodies 10 and 11 and annular ring-shaped inertial bodies 12 and 13. A contact surface 15 with a clamp pulley 4 of the hub 7 is formed in the so-called disc spring shape inclined backward to the outer peripheral side from its central side. When the damper 1 is fastened by a bolt 6 in prescribed torque after it is interposed between the clamp pulley 4 and a fan coupling 5, the contact surface 15 of the hub 7 is elastically deformed in a plate shape by being strongly pressed to a front end surface of the clamp pulley 4. Therefore, in the hub 7, comparatively large pressing force is generated in the direction for pressing the outer peripheral side of the contact surface 15 against the front end surface of the clamp pulley 4, and surface pressure of an outer peripheral part is not reduced.

Title: Forming method of plywood
Inventor: KATO YOSHIAKI
IPC: E04C2/12
Filed: 1998-10-13
Abstract: PROBLEM TO BE SOLVED: To prevent a plywood after forming from twisting, warping or the like and shorten a forming time and consequently improve its productivity by a method wherein a compounded paste, which is prepared by adding a sodium bicarbonate and a propylene carbonate as a cure accelerator to an alkali phenol resin, is employed. SOLUTION: An alkali phenol resin is obtained by reacting phenols with aldehydes in the presence of alkali catalyst. A compounded paste is prepared by compounding a sodium bicarbonate and a propylene carbonate as a cure accelerator, a calcium carbonate, a wheat flour and the water as a filler in the predetermined compounding ratio. Since a plywood can be formed by the forming conditions, which are nearly same as those of the plywood produced by means of a melamine resin or a urea resin when the forming method of the plywood with the above compounded paste is employed, a remarkably small warpage and twisting develop in the plywood, resulting in developing a few non-conforming article. Further, since the plywood formed by this method can ensure the JAS special performances even when a thermal forming time is short. A forming cycle can be shortened.

Title: Manufacture of steam turbine diaphragm
Inventor: KOBAYASHI KAZU
IPC: F01D9/02
Filed: 1988-12-07
Abstract: PURPOSE:To manufacture a diaphragm having high accuracy and high quality by not giving hardening treatment to the inserting part of a diaphragm to a louver when a single nozzle blade is given surface hardening treatment. CONSTITUTION:When a protective coat 2 is applied to a single nozzle blade 1, the coat is not applied to the inserting part of the blade 1 to a diaphragm 3. With this contrivance, when the nozzle 1 is joined to the diaphragm 3 by means of electron-beam welding, the hardening treatment does not exert a bad influence on the welded part, and at the same time separation of the protective coat 2 due to thermal effects of the welding can be prevented. Thus, a diaphragm having high accuracy and high quality can be manufactured.

Title: Apparatus for measuring intensity of photosensor
Inventor: NISHIBE TAKASHI
IPC: G01J1/46
Filed: 1986-12-25
Abstract: PURPOSE:To perform measurement in a wide dynamic range, by quickening the integral time of a photocurrent when the intensity of receiving light is low and making the same long when said intensity is high. CONSTITUTION:At first, a control circuit 6 brings a rest transistor Tr4A to a continuity state by a signal R1 and sets the level of a signal V1 to the potential V0 of a constant voltage source 7. By this method, the integral operation of a condenser 2 starts from the initial value V0 and, when the value V0 is set to an input range wherein a comparator 3 sufficiently performs normal operation, Vref can be allowed to sufficiently approach V0. Therefore, even when the intensity L of receiving light is low, a time ts capable of sufficiently shortening the conversion time ts before input V1 reaches Vref is measured by a timing circuit 5 to be transmitted to the circuit 6. When the intensity L is high in a certain degree or more, a reset transistor Tr4B is brought to a continuity state by a signal R2 and the signal V1 is set to an earth level. When the signal V1 becomes 0, said signal V1 differs from Vref in a certain degree and, therefore, even when the intensity L is high, a conversion time can be measured with good accuracy.

IPC: G02B13/24
Filed: 1993-12-08
Abstract: PURPOSE:To obtain a lens for reading document having good performance without using a special lens such as aspherical face by constituting the lens of two elements in two groups consisting of positive lenses and forming at least one element of the lenses as distributed index lenses. CONSTITUTION:This lens is constituted by successively disposing a first group and second group from an object side toward an image side. Both of the first lens 1 which is the first group and the second lens 2 which is the second group are the positive lenses. At least one element of two elements of these positive lenses are the distributed index lenses. The shape of the distributed index lenses is formed as a meniscus shape and the Abbe number in the convex face position is set larger than the Abbe number of the concave face position in the case of forming the distributed index lenses to an axial type. The correction of various aberrations is facilitated by adjusting the distribution of the refractive indices in such a manner. The approximation of the power position to a symmetrical shape is made possible and the generation of higher order aberrations is suppressed by forming both of two elements of the lenses as the positive lenses in such a manner.
