Title: Arranged in counter weight
Inventor: HARI HAKARA
IPC: B66B11/00
Filed: 1994-06-17
Abstract: PURPOSE: To provide new constitution dissolving the defects of an elevator motor constituted by well-known technology by disposing a rotating motor in a counterweight of an elevator. CONSTITUTION: A rotating elevator motor provided with a traction sheave 18 is disposed in a counterweight 26 of an elevator suspended by ropes 2. A sector-shaped stator of the motor 6 has a diameter larger than the diameter of the traction sheave 18, and the elevator ropes 2 are passed through the opening of the stator. This structure allows the use of traction sheaves 18 of different diameters with rotors of the same diameter. The length of the motor remains short, and the motor/counterweight can be accommodated in the space normally reserved for a counterweight in a hoistway. A motor shaft is disposed in the counterweight 26 substantially midway between guide rails 8, and the same number of ropes 2 are arranged on both sides of the rotor.

Title: Ink jet head
Inventor: HIROSE TAKESADA
IPC: B41J2/055
Filed: 1994-07-11
Abstract: PURPOSE:To print image of high quality which is high in density and stable. CONSTITUTION:A pressure plate 5 comprises a thickest layer part 6 to be connected to a piezoelectric element 12b, a thin layer part 8 provided at the outside of the thickest layer part 6, and a thick layer part 7 provided at the outside of the thin layer part 8. When the piezoelectric element is driven, the thickest layer part 6 drives the thin layer part 8 so as to change a volume of a liquid chamber 4. As the outside of the thin layer part 8 is being the thick layer part, even when the piezoelectric element, for example, the piezoelectric element 12b is driven, a free end of the upper face of the piezoelectric element 12b does not come into contact with the thick layer part 7, so that a pitch L between the piezoelectric elements can be highly dense to be contracted up to a position where the piezoelectric element 12b and the thick layer part 7 overlap.

Title: Elastic clutch
Inventor: BUORUFUGANGU HANKE
IPC: F16F15/30
Filed: 1989-06-22
Abstract: PURPOSE: To adjust buffering more delicately than a conventional method in response to relative rotation by constituting a cross section usable for radial discharge so as to take different value every change of a rotating angle. CONSTITUTION: A partition wall 17 is circumferentially extended with such a width that a radial action face 13 is still positioned outside of a range of the partition wall 17 in a no-torque state or in a small torque state. In a range of a rotating angle (c) meaning large torque, a displacement chamber 16 is barely limited at the side by the partition wall 17. In the case of small torque, a buffer medium is expelled also radially inward outside of the partition wall 17 to obtain a reduced buffering effect, while in the case of large torque, the displacement chamber 16 is almost closed in the range of the rotating angle (c). At this time, the buffer medium only moves to the other side via a specified throttle clearance 15, so that a desired large buffer force is obtained in the large torque range.

Title: Sheet conveying device
Inventor: TAKAHASHI YOSHIHIKO
IPC: B65H9/16
Filed: 1987-06-24
Abstract: PURPOSE: To make it possible to precisely correct an oblique movement by operating a plurality of load applying means arranged in a direction orthogonal to the sheet conveying direction on the upstream side of a sheet conveying means, in accordance with an oblique movement of a sheet detected by a sheet detecting means.  
     CONSTITUTION: A sheet 10 from a cassette is fed into a conveying means 1 through a conveying path by load rollers 5, 6 which are driven by a motor 19 and which are in such a condition that electromagnetic clutches 7, 8 are engaged. Further, the leading end of the sheet 10 is detected by sheet detecting means 13, 15 each composed of a CCD, and at this time, if an oblique movement detecting circuit 21 determines an oblique movement of the sheet 10, a control means 20 stops the motor 19 and disengages the electromagnetic clutch 7 or 8 on the side on which the leading end of the sheet delays. With this arrangement, the preceding side of the sheet 10 slips between a conveying roller 2 and a pinch roller, greater than that of the posterior side thereof so that the delaying side of the sheet is alone advanced to correct the oblique movement. Thus, it is possible to precisely correct an oblique movement.

IPC: C30B15/00
Filed: 1986-07-08
Abstract: PURPOSE:In producing semiconductor single crystal by liquid capsule pulling method, to contrive to improve yield of single crystal, by reducing temperature of melt once before crystal pulling, partially coagulating the surface of the melt, then raising temperature again and carrying out pulling. CONSTITUTION:In producing semiconductor single crystal by liquid capsule pulling method, temperature of melt is reduced in a state where seed crystal is immersed in the surface of the melt and kept for a fixed time. Then the temperature is raised again until the temperature reaches a given pulling starting temperature and the seed crystal is pulled up. In cooling the melt, cooling is carried out mildly (preferably <=10 deg.C/min) and crystal membrane having larger diameter than the diameter of crystal to be formed and smaller than that of a crucible is crystallized from the tip of the seed crystal. In this state, the temperature of the melt is kept constant and the seed crystal is kept for a fixed time in a state where the seed crystal is rotated at a relative speed based on the crucible. Consequently, foams and impurities existing on the surface of the melt are removed and transferred to the outer side of the crucible.

Title: Glassy carbon-coated product
Inventor: OBATA MASAAKI
IPC: C04B41/87
Filed: 1990-06-20
Abstract: PURPOSE:To obtain a glassy carbon-coated product having great dusting preventive effects by coating an inorganic substrate with glassy carbon and then specifying the regular reflectance thereof. CONSTITUTION:The aforementioned product is obtained by coating an inorganic substrate with glassy carbon. The regular reflectance thereof is 2-19%. In the aforementioned coated product, if the regular reflectance is <2%, preventive effects on dusting are small. On the other hand, the reflectance exceeds 19%, peeling of the glassy carbon coating layer readily occurs. The reason why the regular reflectance on the surface of the glassy carbon-coated product is closely related with the dusting amount is considered as follows. The regular reflectance is a measure indicating the smoothness of surface conditions. The dusting properties, i.e., eliminating properties of constituent particles and adhesion and the eliminating properties of adhered particles are strongly affected by the smoothness of the surface conditions.

Title: Construction method of floor
Inventor: KOSHO TAKAYUKI
IPC: E04F15/024
Filed: 1995-06-27
Abstract: PURPOSE: To realize a floor having sufficient strength and extremely excellent sound insulating performance without using an end joist. CONSTITUTION: A particle board 3 which is a subfloor material is supported in the reverse surface by a plurality of height-adjustable support tools 2, and horizontally arranged in a prescribed height position from a floor surface 1. The edge 3a of the particle board 3 near a wall makes contact with a wall surface 7 with a space 11, and is perfectly isolated from the wall surface 7. A reinforcing member 8 is fixed to the reverse surface of the edge 3a of the particle board near the wall by screwing from the upper side. Thus, the strength of this part can be sufficiently increased without arranging an end joist in this part, and since the part in contact with the wall surface as the end joist is not present, a floor extremely excellent in sound insulating property can be realized.  Further, since a sound insulating rubber plate 24 is mounted on the lower end of the support tool 2, the propagation of vibration or noise with the floor surface 1 side can be suppressed, and the sound insulating performance of the floor can be also improved thereby.
