Title: Thermal sheet
Inventor: MIYAUCHI SHINOBU
IPC: B05D7/04
Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To provide a thermal sheet with excellent dynamic and static thermal sensitivity and appropriate rigidity, pliability and strength and further, high handling efficiency, free from the formation of a color in the texture under pressure by making a support of a synthetic resin sheet with specific density. SOLUTION: This thermal sheet is composed of a thermally color forming layer formed on a support. The support is formed of a synthetic resin sheet with, for example, a density containing a cavity of 0.2-0.5g/cm<3> in the support itself. If the density is higher than 0.5g/cm<3> , the thermal sensitivity is lowered, and the tendency of color formation in the texture under pressure is increased. On the other hand, if the density is not higher than 0.2g/cm<3> , the strength of the support is low and it is difficult to form the thermally color forming layer by coating.  The synthetic resin sheet containing a cavity in the support is obtained by a method for mixing a synthetic resin with a foaming material generating a gas by heat and generating foam by extrusion, or mixing the synthetic resin with a non-compatible material against this resin and stretch the synthetic resin sheet obtained by fusion and extrusion into a lengthwise and a crosswise direction.

Title: Digital phase lock loop being made nesting
Inventor: POORU DEII MAAKO
IPC: H03L7/099
Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To maintain synchronization to suppress the occurrence of silence by making phases of generated restoring clocks A and B coincide with each other at the time of alteration of output data in narrow and wide band width DPLLs which perform center bit sampling of the restored data. SOLUTION: Narrow and wide band width DPLLs 402 and 404 use filters 4141 and 432 to generate restored clocks (CK) 410 and 428. At this time, filters output adjustment signals 416 and 434 by signals 412 and 430 which phase detectors 408 and 426 output based on phases of restored data 406 and CKs 410 and 428. Phase adjustment circuits 418 and 436 which use these adjustment signals make phases of CKs coincide with each other by an output signal 422 of a VCO 420, the CK 410, and the detection signal of a signal quality detector 444. After initialization/stabilization of a PLL 402, an FF 438 outputs data 440, which is obtained by sampling center data of data 406, by using the CK 410 or 428 selected by a multiplexer 424. Thus, synchronization is maintained to suppress the occurrence of silence.

Title: Operation control of water cooling machine
Inventor: YORITA MASAMI
IPC: F25D11/00
Filed: 1989-10-06
Abstract: PURPOSE:To permit accurate control of water temperature regardless of the fixing position of a temperature sensor by a method wherein a compressor is stopped when the changing rate of the water temperature is lower than a given value whereas the compressor is conducted again upon water temperature rise and these operations are repeated. CONSTITUTION:The output of a sensor circuit 18', which is outputted upon water temperature detection through a temperature sensor 18 in a tank 2, is converted into a digital signal by an A/D converter 19 while the signal is introduced into a control device 11. The control device 11 obtains the measuring result of water temperature in the tank 2 by the temperature sensor 18 every time when the changing rate of the temperature during this period reaches a given value programed previously, the conduction of a compressor 7 is put OFF through a driving circuit 23 assuming that the water in the tank 2 is cooled sufficiently. When water in the tank 2 is heated by the ambient atmospheric heat thereafter or when the water temperature rises by a specified value, the conduction of the compressor 7 is started. Thereafter, the ON-OFF operations of the compressor 7 may be repeated in such a manner.

Title: Demodulation circuit
Inventor: SHIMIZU SOTA
IPC: H04L27/22
Filed: 1997-09-22
Abstract: PROBLEM TO BE SOLVED: To attain establishment of synchronization and detection of output frequency error at the same time and to make size small by detecting an output frequency error included in a local signal oscillator, based on a median between a maximum value and a minimum value in a temporal waveform of a detector output signal and using detected frequency error information to apply correction control to the output frequency error. SOLUTION: When no error is in existence in an output of a local signal oscillator 2, a modulated signal is given to an orthogonal detection section 1, where an in-phase component and a quadrature component of the modulated signal with a frequency in response to a difference between a frequency of an input modulated signal and the output frequency of the local oscillator 2 are led out at the outputs of multipliers 4, 5. A delay detector 6 detects a relative phase difference between modulated signals corresponding to a symbol change from the signal, and symbol data of a weighted modulation signal at transmission are decoded. The decoded signal is given to code discrimination devices 8, 9, in which sign for the I and Q components is discriminated and the result is given to a parallel serial converter 10, where the components are converted into serial data and then demodulated.

Title: Decoding circuit with chip select input
Inventor: FUTADO KIYOTAKA
IPC: H03M7/00
Filed: 1987-10-30
Abstract: PURPOSE:To reduce power consumption by providing a circuit bringing forcibly a 2-bit logical value in input signals of 4-bit of a decoder into 1 to apply chip select, thereby reducing the circuit scale of chip select remarkably. CONSTITUTION:A BCD input signal corresponding to an input terminal A3 of the most significant bit of a BCD decimal decoder 2 and a 2nd bit input terminal A2 is fed to an OR circuit 1 together with a chip select input signal 3 and the output of the OR circuit 1 is supplied to the input terminals A3, A2. When the logic value of the chip select input signal 3 is logical 1, the level of the input terminals A3, A4 is forcibly to logical '1' by the OR circuit 1 independently of the BCD input 3. In such a case, since the decoder 2 is at the outside of the code conversion range in the logical value, outputs at output terminals Y0-Y9 are not active. When the chip select input signal 3 is logical '0', the signal is not effected by the OR circuit 1 and the input terminals A3, A4 receive the logical value of the BCD input signal 4 as it is. Thus, the decoder 2 is operated normally.

Title: Lens barrel for camera
Inventor: NAKAEDA TAKEHIRO
IPC: G02B7/02
Filed: 1992-09-18
Abstract: PURPOSE:To reduce stray light which reaches an image pickup element after being reflected on a lens barrel internal surface regardless of whether the incidence angle is large or small by using a light shield plate in a specific saw-tooth wave shape and setting a proper reflecting surface corresponding to the incidence angle of light incident on the lens barrel. CONSTITUTION:The light shield plate 19 is fitted to the internal surface bottom part of a main lens barrel 5 with an adhesive by engaging a claw piece 20 with a through hole 21, and plural reflecting surfaces 22 which are sectioned in a saw-tooth shape are formed on its top surface. On a subject side X, theta1<theta2 holds, where theta1 and theta2 are the base angles of a triangle forming a saw tooth. Consequently, a reflecting surface for the incident light is a 1st surface 23 and on the subject side X where much light A having a small angle of incidence is made incident, the light is reflected to the opposite lens barrel internal surface side. On the opposite side X' from the subject side, on the other hand, theta1>theta2 holds. Namely, when the same saw teeth with the subject side X are formed at this position, light B which has a large angle of incidence is reflected by the 1st surface 23 and travels toward the opposite side X' from the subject side and is further reflected by the 1st surface 23 after being reflected by a 2nd surface 24.

Title: Valve
Inventor: MATSUMOTO SHIGEO
IPC: F16K7/07
Filed: 1990-10-15
Abstract: PURPOSE:To prevent lowering of the operation speed of a valve body even when rubber elasticity of a valve body is deteriorated by positively discharging air in a closed space by means of a negative pressure generator when a flow rate of fluid passing through the valve body is increased. CONSTITUTION:A negative pressure generator 23 is connected to a closed space 22, and when a flow rate of fluid passing through a valve body 21 is increased, high pressure air in a closed space 22 is positively discharged by means of the negative pressure generator 23, a valve body 21 is sucked from the outside and deformed in a direction in which a pipe size is increased. Thus, when a flow rate of fluid is increased, deforming operation of the valve body 21 can be effected rapidly. Besides, deformation in a direction in which a pipe size is increased is practicable without depending upon rubber elasticity of the valve body 21. This constitution prevents lowering of the speed of pipe size increasing operation even when rubber elasticity of the valve body is deteriorated with a lapse of time.
