Abstract: PURPOSE:To improve assembling workability and to enhance safety, by connecting a drum main body and the main shaft in the side of a tire molding machine in such a state that said drum main body is always coincided with the axial core of said main shaft. CONSTITUTION:In attaching a drum main body 1 to a main shaft, the drum main body 1 is hung up in a diameter reduced state. At this time, the end surface of a rod 3 in the side of the main shaft and the end surface thereof in the side opposite to the main shaft are present at the position shown by an imaginary line. Similarly, a flange 7 is also present at the position shown by an imaginary line and retracted to the right side so as not to obstruct the inner shaft 24 of a tire molding machine 20. Further, the main body sleeve 2 of the drum main body 1 is clamped into a flange 28 through a bolt 30 while a socket part 31 is aligned and, subsequently, the inner shaft 24 is extruded to the left side and contacted with the rod 3. In this state, a rod 54 with a thread is pushed into the main body sleeve 2 from the left side free end thereof and pierced through the piercing bore 41 of the rod 41 to be threaded into the female thread 53 of the inner shaft 24. By this method, attachment work is completed.

Title: Electric safety mechanism
Inventor: BOKU AMIN
IPC: H01R13/443
Filed: 1996-09-12
Abstract: PROBLEM TO BE SOLVED: To eliminate possibility of erroneous touch with the interior of an apparatus in a state of current conduction and prevent an electric shock accident by making an outer cover unable to be opened in a state of an electric power plug being inserted into a socket and making the electric power plug unable to be inserted into a socket in a state of the outer cover being opened. SOLUTION: A hole 8 larger than an electric power plug 5 is formed in an outer cover 7 and the electric power plug 5 is inserted into an electric power socket 2 through the hole 8. The electric power plug 5 can not be pulled out since the outer cover 7 is overlapped on the electric power plug 5 in a state of the plug being inserted into the socket. A shutter 11 to shut an aperture part 6 formed in a chassis 1 is opened or closed interlockingly with the attachment or detachment of the outer cover 7 and in the state that the outer cover 7 is dismantled, the shutter 11 shuts the aperture part 6 and since the shutter 11 can not be turned back by the outside force, the electric power plug 5 can not be inserted.  As a result, in a state of current conduction to an electric apparatus, touching with the electric parts and electric circuits in the interior of the electric apparatus is prevented.

Title: Noise blanker
Inventor: ONISHI MASAKI
IPC: H04B1/10
Filed: 1990-09-14
Abstract: PURPOSE:To eliminate pulse noise over a wide dynamic range without deteriorating intermodulation distortion characteristic due to adjacent and adjacent-to- adjacent channel disturbance wave by rectifying and smoothing part of an output of an amplifier via a BPF, giving the result to an automatic gain control circuit and controlling the gain of the amplifier with its output. CONSTITUTION:When a disturbing wave in the vicinity of a carrier such as adjacent and adjacent-to-adjacent channel disturbance wave is inputted, a mixer 1 converts the disturbing wave into an IF frequency by a mixer 1. Then the converted signal is amplified by an amplifier 5 and its output passes through a band pass filter BPF 8 and rectified and smoothed by a rectifier smoothing circuit 9 to decrease the gain of the amplifier 5 via an AGC circuit 10. Thus, intermodulation distortion generated in the amplifier 5 is reduced, thus, pulse noise is eliminated over a wide dynamic range without deteriorating the intermodulation distortion characteristic due to the adjacent and adjacent-to- adjacent channel disturbance wave.

Title: Rolling bearing
Inventor: UEDA KIYOTOSHI
IPC: F16C33/82
Filed: 1987-09-29
Abstract: PURPOSE:To prevent a magnetic fluid used as a lubricant from splashing outside by providing gaps which have magnetic fields between a pair of seal members, and a first raceway track member and setting at least one of the gaps to be an air gap. CONSTITUTION:A magnetic fluid is used as a lubricant, while gaps g2, g2 having magnetic fields generated by circular magnets 28, 28 are formed between a pair of seal members C1, C1 and a first raceway track member 21, at least one of gaps is an air gap. Therefore, even if the magnetic fluid as the lubricant splashes by a relative rotation between the first and a second raceway track members 21, 22, and the fine splash thereof is going to pass the air gap g2 and scatters outside, it is captured by means of the magnetic field and adheres to the seal members C1 or the first raceway track member 21. In addition, since the inner and outer spaces of a bearing are communicated to each other through at least one of gaps g2, the fluid never breaks through the other gap g2 and splashes therearound due to its temperature rise even if it is interposed in the gap g2.

Abstract: PURPOSE:To provide a ball end mill in which tip strength of an end cutting edge is secured and of which manufacturing is easy. CONSTITUTION:A first cutting part 16 is formed on an axis of a tip of a tool body and a second cutting part 18 is discontinuously formed from the first cutting part 16 toward an outer peripheral part. In the first cutting part 16, a first face 20 and a second face 22 are formed at an equal angle to the axial direction, and rake faces 20a, 22b are formed on the rotation direction sides (refer to an arrow mark) of respective faces 20, 22, while flanks 20b, 22a are formed on the opposite sides thereof. Since rake angles of the rake faces 20a, 22b are set negative, even when clearance angles are set large, strength of edge tips are sufficiently secured. Accordingly, influence due to thrust from the flanks in cutting is decreased to the utmost and cutting with high feeding speed can be realized. Since the rake faces 20a, 22b can be formed on the same plane as the flanks 20b, 22a, manufacturing can be facilitated.

IPC: G02B6/13
Filed: 1988-09-27
Abstract: PURPOSE:To obtain an optical circuit board which hardly produces crosstalk and is low in propagation loss by forming a resin layer containing a light absorbing agent and/or light scattering blocking agent on the outside of the clad of a core through which light is transmitted. CONSTITUTION:This optical circuit board 1 is constituted of four layers of a core 11, the clad layer 12 of the core 11, resin layer 13 containing a light absorbing agent and/or light scattering blocking agent, and substrate 14 holding the layers. The resin layer 13 is formed on the outside of the clad layer 12. Because of the resin layer 13, the light leaking out from the core 11 hardly goes out from the clad layer 12 and outside light hardly get into the core 11 through the clad layer 12. In addition, the light (stray light) getting out from the core 11 of a certain optical waveguide can be reduced by the resin layer 13 which absorbs the stray light and blocks the scattering of the stray light. Therefore, crosstalk can be prevented and the propagation loss of the optical circuit board can be reduced.

IPC: H04R3/04
Filed: 1991-08-30
Abstract: PURPOSE:To enable stable operations not affected by the jitter of an input signal or the change of a sampling frequency by converting the input digital signal to the digital signal of an asynchronous reference clock different from the sampling frequency. CONSTITUTION:The reference clock of 128fsi, for example, locked to input digital data in respect to a sampling frequency fsi is generated from a PLL circuit part 3 and supplied to a sampling frequency conversion part 5. The digital signal of the sampling frequency fsi is converted to the digital signal of a reference clock fso from a clock generator 8 by the sampling frequency conversion part 5 and transmitted to a digital signal processing part (DSP) 6 together with calculated interpolation data. The DSP 6 executes a prescribed digital signal processing based on the reference clock fso from the clock generator 8. Thus, the degradation of sound quality caused by the jitter, etc., of the input digital signal in the case of D/A conversion can be eliminated.
