Title: Pll circuit
Inventor: BABA MITSUO
IPC: H03L7/093
Filed: 1996-12-05
Abstract: PROBLEM TO BE SOLVED: To reduce jitter and a phase error of an output signal after leading-in due to a dead zone around a zero phase difference of two input signals existing in a phase comparator in a PLL circuit. SOLUTION: This PLL circuit consists of an edge comparison type phase comparator(PFC) 2, a charge pump circuit(CP) 3, a lowpass filter(LPF) 4, a voltage control oscillator(VCO) 5 and a divider (1/n) 6. In such cases, an output stationary jitter and a stationary phase error are reduced by providing a modulation circuit 1 which modulates an edge in 1/2 cycle of the signal in the direction of a time axis to a reference signal REF side which is inputted to the PFC 2.

Abstract: PURPOSE: To reduce sensitivity to a deviation due to impact and vibration by arranging a second part extending from a first part connected to a shadow mask body structure in a spring, and arranging an offset section to position the center of an opening hole fitted to a stud connected to this part on a central lengthwise shaft surface passing through the second part. CONSTITUTION: A spring 46 has a first part 52 parallel to a plate material 48, and a strip-shaped second part 54 extends from the first part 52, and forms an acute angle with the plate material 48. An offset section 56 is arranged from the second part 54 in the direction separating from the plate material 48. A third part 58 is arranged in a shape almost orthogonal to a lengthwise central axis A-A of a stud 44 from this offset section 56, and an opening hole 50 fitted to the stud 44 is arranged in the third part 58, and a lengthwise central surface B-B of the second part 54 crosses in the almost center of the opening hole 50 with the lengthwise central axis A-A of the stud 44. Therefore, even if any stress is applied in parallel to the second part 54, since the spring 46 does not curve, influence of impact and vibration is reduced.

Title: Method for storing flexible printed wiring board
Inventor: TAKAMURA ICHIRO
IPC: H05K1/02
Filed: 1998-11-17
Abstract: PROBLEM TO BE SOLVED: To prevent a wiring board from being brought into contact with or sliding over other components, etc., in the periphery by installing a balance weight on the inside of the folded wiring board. SOLUTION: A flexible printed wiring board 13 is stored in the main body 11 after being folded at a bent part F. On the inside of the bent part F and in the vicinity of it of the wiring board 13, a plurality of weights 17 are installed. Due to this structure, the wiring board 13 droops due to the weight of the weights 17, thereby bringing the wiring board 13 into noncontact with a cover 16 installed above the main body 11. Even when a printing head 12 is moving, the wiring board 13 never slides over the cover 16. The wiring board 13 is thus prevented from being brought into contact with or sliding over other components, etc. As a result, the wear or the damage of the wiring board 13 and consequential disconnection or short-circuit of wires can be prevented.

Title: Display provided with diffraction grating pattern
Inventor: KISHIMOTO YASUSHI
IPC: G02B5/18
Filed: 1997-11-27
Abstract: PROBLEM TO BE SOLVED: To easily provide a display with improved decorativeness and security without using a fine dot in a constitution unit and without the need of time and labor by adding a pattern composed of recessed and projected parts whose height and pitch are larger than a diffraction grating to a diffraction grating pattern surface. SOLUTION: A relief type diffraction grating is appropriately arranged on the surface of a substrate and a reflection layer is formed on the surface. To the diffraction grating pattern surface, the pattern composed of the recessed and projected parts whose height and pitch are larger than the diffraction grating is added by emboss formation. In the recessed and projected pattern, displaying brightness is converted to the size of the area of the recessed part (or projected part). For instance, a mask original plate is prepared by dotdecomposing the pattern, a mask is formed on a metallic plate from the mask original plate and a stamper with the recessed and projected pattern is prepared by etching. By adding the recessed and projected pattern to the surface where the diffraction grating pattern is formed, by the stamper, this display is attained.
