Title: Structure of ribbon of coated optical fibers
Inventor: KOBAYASHI KAZUNAGA
IPC: G02B6/44
Filed: 1994-12-06
Abstract: PURPOSE: To reduce the transmission loss of the ribbon of coated optical fibers by arranging the center line of a coated optical fiber array at a position where it is not aligned with the lateral center line of the ribbon of coated optical fibers. CONSTITUTION: The ribbon 10 of coated optical fibers has the center line C of its optical fiber array displaced by a displacement quantity δ to above the center line L of the ribbon 10 of coated optical fibers. Consequently, the interval (s) from the outer peripheral reverse surface of the optical fibers 4 to the reverse surface (f) of the ribbon is the displacement quantity δ larger than usual (the center line of an optical fiber array is aligned with the lateral center line of a ribbon of coated optical fibers.) and the lower coating thickness is at least 50μm. Consequently, the local compressive stress in the thickness direction of the ribbon under surface (f) is sufficiently dispersed before reaching the under surface of the optical fiber 11 and no local large force reaches the under surface of the optical fiber.

Title: X-y recorder
Inventor: SASAKI NAOTAKA
IPC: G06F3/13
Filed: 1987-12-28
Abstract: PURPOSE:To obtain an X-Y recorder preventing the slippage of any recording paper even when it has no feeding hole and thus enabling the attainment of an exact quantity of movement, by a construction wherein a plurality of projections having sharp edges are provided on a drive roller so that they form grooves in the axial and circumferential directions on the outer surface of the roller, and a trapezoidal groove is provided at least in one of the axial and circumferential directions in the grooves. CONSTITUTION:On the occasion when minute projections 13 are formed on the outer surfaces of drive rollers 10 and 12, cutting is so made as to form trapezoidal grooves 14 and 16 so that the amount of intrusion of recording paper 1 be a prescribed value, and thereby the minute projections 13 having sharp edges respectively are formed. Since an effective diameter D set by the trapezoidal grooves 14 and 16 formed on the outer peripheral parts of the drive rollers 10 and 12 regulates the amount of intrusion of the recording paper, according to this constitution, the amount of movement at piD can be obtained exactly with one rotation of the drive rollers 10 and 12 even when the recording paper is altered. Besides, the respective edges of the minute projections 13 are formed with sharp angles, and thereby dislocation of the paper such as slippage is prevented.

Title: Control board box
Inventor: SATO SHOJI
IPC: A63F7/02
Filed: 1997-12-01
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of inconvenience by forming the control board box of a game machine of a transparent plastic. SOLUTION: In this control board box, a transparent conductive film 62 is stuck to the bottom 18a of a lower box part 18. Shieldability is secured since the conductive film 62 absorbs electromagnetic waves and also a fault is prevented from being generated in the operation of a control substrate by excessively stored static electricity since the static electricity is discharged by air discharge from the conductive film 62. Since the conductive film 62 is connected through an aluminum plate 46 and a corner electrode to the terminal for grounding of the control board, the conductive film 62 is grounding through the terminal for grounding and the storage prevention effect of the static electricity is improved further.

Title: Bit synchronization circuit
Inventor: IGAWA KEIICHI
IPC: H03L7/06
Filed: 1989-12-19
Abstract: PURPOSE:To lower the operating frequency of the circuit to make the circuit constitution easy and to reduce power consumption by providing plural oscillation circuits whose oscillating frequency differs, and selecting an oscillation circuit minimizing the frequency difference between input and output. CONSTITUTION:A phase difference between an NRZ signal inputted from an input terminal 11 and a recovered clock is compared by a phase comparator 13, which outputs the result of phase comparison. A U/D counter 14 integrates the result of phase comparison outputted from the phase comparator circuit 13 and outputs a control pulse to an oscillation circuit selector 15 and is reset when a prescribed value is integrated. Upon the receipt of a control pulse, the oscillation circuit selector 15 integrates the pulse. When frequencies between the input and output have a difference, since the control pulse is consecutive unidirectionally, the integration value is increased to a value and the oscillation circuit selector 15 selects one of oscillation circuits 16a-16n so as to decrease the difference of the frequencies. Thus, the operating frequency of the circuit is lowered, the circuit constitution is facilitated and power consumption is reduced.

Title: Flattened etching
Inventor: INAMOTO YOSHIMASA
IPC: H01L21/027
Filed: 1987-12-25
Abstract: PURPOSE:To prevent an alignment mark from being eliminated by etching, by a method wherein etching is performed, after the resist layer of a part corresponding with the alignment mark is previously eliminated by exposing and developing. CONSTITUTION:The resist layer 31 of a part corresponding with an alignment mark 11 is exposed and developed, and this resist layer 31 only is eliminated, thereby forming an aperture 32 in a resist layer 30. A step-difference 21 corresponding with the alignment mark 11 is exposed from the aperture 32. Etching is performed in the manner in which the etching rate of a nitride layer 20 and that of the resist layer 30 become equal. A step-difference formed on the surface of the nitride layer 20 is eliminated, and the surface of the nitride layer 20 is flattened. The nitride layer 20 stacked on the upper part of the aperture 32 is set thinner than the resist layer 30, but large difference is set between the etching rate of the resist layer 20 and that of a wafer 10. Therefore the alignment mark 11 formed on the wafer 10 is never eliminated by etching.
