Inventor: TSUJI TAKESHI
IPC: B29K105/08
Filed: 1998-05-12
Abstract: PROBLEM TO BE SOLVED: To increase the drive capability and prevent a pitch noise from being generated by winding a rib rubber layer, a core and a spine rubber layer around a mold with spiral grooves cut in parallel side by side and spirally cutting a batch of a few spiral grooves set in parallel, in a belt sleeve obtained through vulcanizing following the winding process. SOLUTION: An unvulcanized rib rubber layer 4 and an adhesive rubber layer 5 are wound around a mold 2 with a desired number of spiral grooves cut in parallel for example, three pieces of the spiral groove, and further a batch of two core wires 6 are wound around the spiral. After that, the adhesive rubber layer 5 is once again wound around the core wires 6 are a rubber-coated fabric 7 is wound to vulcanize the rubber material to obtain an integrated belt sleeve which is in turn, released from the mold 2. In addition, a cutter is moved at a specified velocity in the width direction of the belt sleeve to cut the sleeve spirally and thereby an open-end belt is obtained. Thus it is possible to easily manufacture the open end V-ribbed bent having a desired number of ribs.

IPC: B23H1/02
Filed: 1986-06-03
Abstract: PURPOSE:To prevent accidents due to damage of an electrode, by detecting the degree of insulation of an insulative machining fluid existing in the gap between the electrode and a workpiece and by comparing thus detected value with a reference value to control the height of pulse voltage applied across the interpole gap. CONSTITUTION:A control instruction signal generating device 17 superposes high frequency alternate voltage from an electrical sources 18 during a deionizing period or the quiescent time of pulse voltage applied between a wire electrode 2 and a workpiece 1 from a machining power source 15, and a current detector 6 detects interpole leakage current running due to the lowering of insulation of the machining fluid 3 which is caused by machined chips, so that thus detected current is compared with a preset reference value to discriminate the interpole condition. With the result of the discrimination a control instruction signal is fed to a control device 14 and a machining power source 15, and if there would be any risk that the degree of insulation of insulative machining fluid 3 is lowered so that abnormal electric discharge occurs, the height of pulses applied across the interpole gap from the machining power source 15 is controlled. Thus, it is possible to prevent breakage of the wire electrode without the machining rate being lowered.

Title: Decorative coating
Inventor: KATOU SHINJI
IPC: B05D5/06
Filed: 1978-10-19
Abstract: PURPOSE: To perform a decorative work in a simple method, short period, and low cost way, by using ultraviolet curable coating material to form a depression with the same pattern as an object to be embedded and is followed by embedding the object.  
     CONSTITUTION: After an undercoat layer 2 has been formed on the substrate 1, an intermediate coat layer 3 is applied by using an ultraviolet curing coating material consisting of lacquer and ultraviolet curable resin to form a layer of 50W200μm in thickness. The intermediate layer 3, after being placed with an object 4 to be embedded such as a metal foil, is irradiated by ultraviolet ray from a high pressure mercury lamp or the like. The location of the object 4 which is uncured, after cooled, is dissolved by solvent and removed. This results in a depression 5 with the same shape as the object 4, into which the object is embedded using adhesive. Such simple process provides decorative products in a short period and inexpensive way without needing tranining or skill in the process.

Title: Speed controller of motor
Inventor: IKENOUE YOSHIKAZU
IPC: H02P1/16
Filed: 1983-07-14
Abstract: PURPOSE:To improve the transient response by using as a speed control signal the sum of the correction amount in response to the error between a detection speed and a reference speed and the correction amount for reducing stepwisely in response to the conversion to the reference speed of the detection speed. CONSTITUTION:An encoder 2 outputs a pulse signal of the frequency proportional to the rotating speed of a DC motor 1, and a microcomputer 6 outputs as a speed control signal the sum of the speed error between the interval of the pulse signal and the time interval corresponding to the set rotating speed and the correction amount K. The amount K is the maximum positive value Ks at the starting time. If the speed error is larger than the minumum allowable value and positive within the allowable range, the amount K is formed to 1/2 so that the sign is negative. Then, the amount K is set to 1/2 whenever the sign of the speed error alters, and the sign is altered. When the amount K becomes minimum KMIN, only the sign is varied.

Abstract: PURPOSE:To prevent a contact from abnormal wear and fusion deposition by forming two contact pieces from a clad plate made of a good electroconductive material and a magnetic material, and laying at least a part in parallel with one another in areas other than the contact installed part. CONSTITUTION:This contact mechanism consists of No.1 contact piece 53 and No.2 contact piece 54 made of a clad plate of good electroconductive material 51 and magnetic material 52. The No.1 contact piece 53 is equipped with a contact 55 at the tip while the No.2 contact piece 54 with a contact 56 at a point a little backmore from the tip, wherein the magnetic material 52 at the tip 54a of No.2 contact piece 54 is parallel to that portion of No.1 contact piece 53 mating therewith. In this contact mechanism current i produces a line of magnetic force phi, which passes the magnetic material 52 of the portion 53a of No.1 contact piece 53 and the magnetic material 52 at the tip 54a of No.2 contact piece 54 where no current flows, and electromagnetic attraction force is generated between the magnetic materials 52, 52 of the two parts 53a, 54a. This suppresses electromagnetic repulsion and separation of the contacts when excessive current is passing. Thus the contacts are prevented from abnormal exhaust and fusion deposition.

Title: Shear press
Inventor: INAMURA YOSHIAKI
IPC: B21D22/02
Filed: 1981-08-20
Abstract: PURPOSE:To prevent taking-out of two pieces at one time by providing one die with a rotary member equipped with a punch to be fitted in a hole, bored in the other die, by allowing it to rotate in synchronization with the relative movement, and by forming an emboss at different positions of a material. CONSTITUTION:When the upper die 5 sinks, a cam driver 29 comes down to slide a rod 25 with the aid of a cam slide 28, that will rotate a rotary body 19 through a ratchet and a pawl to change the position of the punch 21. Because thereafter a pad 6 is pressed against a block part 17, with a material W to be processed interposed, following the shearing motion with the upper and lower edges 4, 2, the punch 21 is fitted in a hole 16 with the material W interposed to form an enboss E. This action is repeated with every elevation and sinking of the upper die 5, and the punch 21 changes its position every time to form embosses at different locations. Accordingly, taking-out of two pieces at one time can be prevented even though two or more materials W are piled up one over another because of existence of a gap corresponding to the depth of the emboss E.

Filed: 1983-07-18
Abstract: PURPOSE:To confirm the transmission of a transmission data frame without generating a timewise delay by detecting collision between a post-amble transmitted in succession to the transmission data frame and a response frame on a communication medium. CONSTITUTION:A microprocessor MPU1 in a transmitter of bus type random access communication control system transmits a transmission data to a transmission buffer 2 and transmits a transmission request to a transmission control circuit 3 respectively at data frame transmission. When the circuit 3 detects an idle communication medium 11 via a carrier detecting circuit 8, the circuit 3 transmits a preamble from a preamble generating circuit 4 to the medium 11 via a network transceiver 6. When a collision detecting circuit 7 detects that transmitted preambles are not collided with each other on the medium 11, the buffer 2 transmits a transmission data and a post-amble is transmitted from a post-amble generating circuit 5. When the collision detecting circuit 7 detects a collision on the medium 11 during the transmission of the post-amble, it is decided that an opposite reception station receives correctly the transmission frame and the response frame is returned.
