Title: Automatic fitting device for piston ring
Inventor: MORI KENZOU
IPC: B23P19/08
Filed: 1979-09-12
Abstract: PURPOSE:To enable automatic fitting of a piston ring to a positioned piston by a method wherein the piston ring fed to and engaged with the outer-peripheral surface of a cup member is made to conduct the downward displacement, while being expanded and transformed elastically by the downward motion of a pressing part. CONSTITUTION:The lowest-positioned piston ring 26'' out of those in a magazine 28 is pushed out from a feedingport part 34 by the operation of the 5th air cylinder 29 and is engaged with the outer-peripheral surface of a cup member 7. Next, a piston 9 is stopped on a carrying rack 20 under the cup member 7 by the 3rd air cylinder 19. After that, the piston 9 is positioned by the operation of the 4th air cylinder 23. Then, the cup member 7 is pushed down by the 1st air cylinder 4 and made to approach the top part of the piston 9 so as to cover the top. Under the condition, a pressing part 16 is moved downward by the 2nd air cylinder 13, thereby the piston ring 26 is made to do the displacement toward the bottom surface of the cup member and is expanded and transformed elastically, and thus the piston ring 26 is fitted in the ring groove 9'' of the piston 9.

Title: Disc recording/reproducing device
Inventor: HORINO TAKAYUKI
IPC: G11B7/085
Filed: 1995-05-16
Abstract: PURPOSE: To obtain a disc recording/reproducing device in which the time, required for reading a data from a disc recording medium can be shortened. CONSTITUTION: When a CPU 13 retrieves and reads out a data at an address on an MD 1 requested by a host computer, the reading operation is temporarily interrupted upon occurrence of a trouble, e.g. missing of SYNC from a reproduced signal, and a read start address is shifted forward before restarting the reading operation. Since the operating conditions of a CD-ROM encoder/decoder 11 can be brought into SYNC protective mode in the early stage, the data can be read out smoothly using a SYNC inserted into the CD-ROM encoder/ decoder 11 even if the SYNC is missed at the same address as the previous time and thereby the time required for retrieval can be shortened.

IPC: H04B7/005
Filed: 1985-05-30
Abstract: PURPOSE:To eliminate a channel selection error by selecting a channel not stored when the own station selects a channel for a call. CONSTITUTION:A control channel is supervised at the standby of a call from other station to store the designated channel by the other station into a memory device 36.

Title: Method and device for determining optical quality of plate glass or plate glass product
Inventor: BORUFUGANKU BONGARUTO
IPC: G01N21/89
Filed: 1989-05-12
Abstract: PURPOSE: To decide the absolute value of the refracting power corresponding to each point in a defective area by providing a step for deciding a silhouette, a step for generating a digital signal, a step for forming a difference signal, a step for forming a quotient, and a step for deciding the absolute value. CONSTITUTION: The light from a light emitting device 2 is cast on a glass ribbon 1 at a prescribed incident angle. A silhouette 7 generated by float distortion appears on a projection screen 3 in the form of bright- and dark-colored strips. A video camera 4 takes the picture of the silhouette 7 and supplies the picture to a picture processing system 8 and the system 8 digitally processes the picture. A computer in the system 8 supplies the digital measured values of the actual luminance L(x) at each image point to a subtracting element through symmetrical filters and the element forms the difference ΔL(x) between measured value and the reference luminance signal L0(x) of a specific image point. Then the computer supplies the difference ΔL(x) to a dividing means to form a quotient ΔL(x) /L0(x) .  Then, a changing means multiplies the quotient by a prescribed constant K. Thereafter, a refracting power file is obtained by calculating each refracting power from D(x) =K.ΔL(x) /L0(x) .

Title: Module fixing structure of digital electronic time piece
Inventor: WATANABE MASASHI
IPC: G04G17/02
Filed: 1983-06-29
Abstract: PURPOSE:To fix a module without an independent member which fixes the module to an armor case by providing an elastic projecting part on a cell supporting frame and bringing direcrly the projecting part into contact with the rear cover of the armor case to fix the module. CONSTITUTION:A circuit substrate 12 is positioned on the cell supporting frame by a pin 10, and the cell supporting frame 14 and the circuit substrate 12 are fixed in a part 13 by screws. The circuit substrate 10 in the part of the projecting parts 11 is made smaller so that the projecting part 11 are brought into contact with the rear cover of the armor case directly. The cell supporting frame 14 is higher than the circuit substrate 12 in a section a-a but the cell supporting frame 14 is under the circuit substrate 12 on the structure in sections b-b and c-c, and therefore, projecting parts 11 pass through the circuit substrate 12, but they have the same height. Since elasticity is given to projecting parts 11, the module is fixed accurately when the module is put into the armor case. In case that the circuit substrate is arranged in the most rear side (rear cover side) of the module, elastic projecting parts are formed on the cell supporting frame to fix the module in the armor case.

Abstract: PURPOSE:To changeover only a section, which corresponds to a fault, to a stand-by circuit by detecting an AIS (alarm indication signal) signal sent from a preceding station by only a low-priority station in the section when the fault occurs. CONSTITUTION:An AIS signal (a) composed of an all-''1'' bipolar signal discriminated from normal data is converted by a bipolar/unipolar converting circuit 1 into a unipolar signal (b).

The output of the converting circuit 2 is supplied to a pulse detecting circuit 3 as a 100% duty unipolar signal (c) and a ''0'' appears at the output terminal of the circuit 3 as a pulse break. A pulse detecting circuit 5, on the other hand, detects a clock signal (d) and a ''1'' appears at its output terminal. Both those signals ''0'' and ''1'' are applied to an EX.OR circuit 6 and at its output terminal (e), a signal having logic ''1'' indicating the presence of the AIS signal appears.

Abstract: PURPOSE:To prevent the generation of the leakage of an internally enclosed gas and the exfoliation, etc. of a welding section by forming an annular groove to the unbonded surface of a flange through press work while forming an annular projecting section to the unbonded surface with the formation of the annular groove. CONSTITUTION:With the cap 10, the high annular projecting section 10B is formed to the unbonded surface of the flange 10A for the cap while the annular groove 10C generated with the formation of the projecting section 10B is formed on the unbonded surface side of the flange 10A.
