Patent JP-S6457237-A (JP)
Title: Optical scanner
Inventor: KAWAGISHI HIDEYUKI
IPC: B41J2/445
Filed: 1987-08-28
Abstract: PURPOSE:To eliminate the need of an expensive driver, and to execute driving with an inexpensive driver, by moving a light opening part and a light closing part of two liquid crystal optical shutters at an equal speed in the same direction, and allowing a light beam to scan at a high speed by length of a desired picture element portion. CONSTITUTION:In light beams radiated from a linear light source 5, a part of the light beams is obstructed by a light closing part of the first liquid crystal optical shutter 1a, and the other light beam reaches the second liquid crystal optical shutter 1b. By the second liquid crystal optical shutter 1b, the light beam in the advance direction is also obstructed, and the light beam transmits through an optical scanning part 6 by length (l) of a desired picture element portion. The light opening part and the light closing part of each liquid crystal optical shutter can be controlled by increasing the brightness and darkness of a liquid crystal molecule or the inversion area, along the longitudinal direction. Accordingly, boundaries 2a, 2b can be scanned in a state that the length (l) of the desired picture element portion remains held, by increasing the light closing part as for the first liquid crystal optical shutter 1a, and increasing the light opening part as for the second liquid crystal optical shutter 1b by following up said increase. In such a way, an expensive driver becomes unnecessary.

Title: Piezoelectric vibrator having etching monitor
Inventor: CHIBA AKIO
IPC: H01L21/302
Filed: 1984-10-11
Abstract: PURPOSE:To monitor the etching state of a piezoelectric diaphragm by providing split electrodes in pairs to one side of the piezoelectric diaphragm and applying an AC current to the split electrodes to as to attain horizontal electric field excitation. CONSTITUTION:When a crystal resonator is used for the piezoelectric vibrator, since the resonance frequency is inversely proportional to the thickness of a crystal flat plate 2 in general, a resonance frequency (f) inversely proportional to the thickness (t) including the thin split electrode 3 provided on one side is expressed as f=K/t (where K is a thickness frequency constant). When the face opposite to the face having the split electrodes 3 is subject to, e.g., dry etching or reactive ion etching under vacuum, the increment DELTAf of the frequency corresponding to the decrement DELTAt of the thickness thereby is expressed as DELTAf=-K'f<2>DELTAt, and the etching amount DELTAf is can be known by monitoring the DELTAf. A loop oscillating circuit network known as the transmission method having a phase adjusting amplifier 8 is used for the purpose.

Title: Tracking method for optical pickup
Inventor: ENDO KIYONOBU
IPC: G11B7/09
Filed: 1985-09-25
Abstract: PURPOSE:To attain a detection with high sensitivity by detecting a change in the light intensity distribution of split far field patterns photoelectrically and obtaining a tracking error signal from the phase difference of a detection signal. CONSTITUTION:When the center axis of an information track and the center of a light spot are not coincident, the symmetry of the far field pattern is unbalanced and in detecting a light photoelectrically at the light-receiving sections 13, 14 of a photodetector, a phase difference is caused in the detection signal. A tracking error signal is obtained from the phase difference signal. Thus, high density detection is attained.

Title: Composite diaphragm
Inventor: FUSE YUUZOU
IPC: H04R7/10
Filed: 1981-12-28
Abstract: PURPOSE:To obtain a composite diaphragm which is suited to a speaker, by using a core member in which the projected and depressed parts of trapezoidal and trigonal pyramid forms are regularly arranged in a prescribed relation with each other. CONSTITUTION:For a core member 11, a number of projected parts 12 formed into trapezoidal regular triangles with the same size are regularly arranged and in a prescribed formation. A surface member 14 is adhered to the upper surface side of an edge face part 12s of a regular triangle with use of an adhesive. At the same time, a surface member 15 is adhered to the lower surface side of an edge face part 13s of a regular triangle at each depressed part 13 with an adhesive. Therefore an equal adhered area is obtained between the members 14 and 15 to ensure a good balance of strength between both surface members. The member 11 as a whole has extremely large rigidity as the projected parts contiguous with each other are supported to each other. Furthermore its dyanamic characteristic becomes isotropic and the directivity of the bending strength is eliminated.

Title: Serial printer
Inventor: YOSHIKAWA SHIGERU
IPC: B41J35/14
Filed: 1985-09-26
Abstract: PURPOSE:To provide a serial printer suitable for fast printing through the reduction of carrier weight by installing a cam floor on the bottom of an ink ribbon cartridge, an inclined cam formed integrally with a ratchet wheel on a carrier and a link ratchet on a frame. CONSTITUTION:In a serial printer with a multicolor ink ribbon-stored ink ribbon cartridge mounted, a carrier 4 moves in the arrow B direction beyond a normal printing range, if a color ribbon switching control sequence generates. Then if a ratchet wheel reaches an arrow C position, this ratchet wheel 9 is engaged with a ratchet 15a of a link ratchets 15 to rotate an inclined cam 9a by a required value in accordance with the movement amount of the carrier 4. In this case, the carrier 4 shuttles back and forth over the range between arrows C and D according to the rotation amount. Thus the inclined cam 9a pushes up a cam roller 2a held to the bottom of an ink ribbon cartridge 2 to rock said cartridge 2 to set a multicolor ink ribbon 1 to a predetermined position.

Title: Frequency shift keying equipment
Inventor: KAWAI KAZUO
IPC: H04L27/12
Filed: 1990-08-10
Abstract: PURPOSE:To prevent malfunction even in the presence of a DC component by using a switch circuit to disconnect a phase detector and a loop filter in a PLL for a period when the DC component in a modulation digital signal is detected. CONSTITUTION:When a PLL detects consecutive 1s or 0s, it is desired that the loop control is tentatively stopped and the state just before the stop is stored till a succeeding conversion point comes. An output 18 of a DC component detection circuit 8 represents correct detection of consecutive 1s or 0s of an input 16 more than that by an input waveform 16. Thus, the output 18 is delayed by a delay circuit 9 the same as a delay by a roll-off filter 2 and the result is fed to an analog switch 10, then the loop control is tentatively stopped for a period only when consecutive 1s or 0s is in existence. An output frequency of a VCO 4 during the tentative stop depends on the sum of a stored charge voltage in a capacitor in a loop filter 6 and a voltage produced for the consecutive 1s or 0s fed from the roll-off filter 2.

Title: X-ray stress measuring method
Inventor: OTANI KIYOBEI
IPC: G01L1/00
Filed: 1997-08-08
Abstract: PROBLEM TO BE SOLVED: To enhance resolution of stress distribution in the depth direction of an object by detecting crystal strain of the object at a plurality of diffraction angles and estimating the stress of the object corresponding to the crystal strain. SOLUTION: An X-ray detector 12 detects X-rays 16 diffracted by an object 3. An X-ray tube 11 is interlocked with the X-ray detector 12 and they are moved reversely in order to vary the diffraction angle θ sequentially thus detecting strain of crystal lattice at different positions in the depth direction of the object 3. When the strain of crystal lattice is multiplied by Young's modulus, corresponding stress can be estimated. Effective intrusion depth of X-rays 15 diffracted on the crystal lattice face from the surface of the object 3 varies in specific relation to the diffraction angle θ. Consequently, the stress far required effective intrusion depth can be measured sequentially while varying the diffraction angle θ. According to the method, resolution of stress distribution in the depth direction from the surface of the object 3 can be enhanced significantly.
