Title: Differential phase-difference thermometer using optical anisotropic crystal
Inventor: AMAYA KAZUO
IPC: G01K11/12
Filed: 1986-10-21
Abstract: PURPOSE:To measure a fine temperature difference by arranging two crystals which have optical anisotropy in the directions of orthogonal (a) and (b) axes and are equal in length in the (c)-axial direction perpendicular to said axes. CONSTITUTION:Light from a light source 1 is polarized by a polarizer 2 into linear polarized light, which is incident along the (c) axis at 45 deg. to the orthogonal optically anisotropic axes (a) and (b) of a crystal element 3 to become elliptic polarized light. Then when it is incident on a crystal element 4, a phase difference is generated between its crystals. This elliptic polarized light passes through a phase modulating element 5 to become phase-modulated elliptic polarized light, which enters a 1/4 wavelength plate 6; and an analyzer 7 imposes intensity modulation and a photodetector 8 generates an AC signal of modulation frequency, so that its component and phase difference vary with the phase difference of the optical path. This signal is inputted to a phase detector and amplifier 9 and then its output is zero when the phase difference of the optical path is pi, thereby obtaining a positive or negative voltage signal according to whether the phase difference is large or small. This is returned to the element 5 to measure the level of the signal, and consequently the phase difference of the optical path which is smaller than pi is accurately obtained to know the temperature difference between the two crystals from the phase difference, so that when the temperature of one crystal is made constant, the temperature of the other crystal can be measured.

Title: Image recorder
Inventor: NAGUMO AKIHIKO
IPC: G03D13/00
Filed: 1989-09-25
Abstract: PURPOSE:To carry image recording materials while they adhere to each other and while they are held between the endless press-welded belt and the heating drum and to form a picture free of irregularity by applying the rotating/driving force of a driving source to one of plural winding rollers, rotating the endless press-welded belt, transmitting its rotation to the drum by means of the frictional force of the belt against the drum, and thereby causing the drum to follow the rotation. CONSTITUTION:When the winding roller 140 rotates by means of a motor 194, the endless press-welded belt 118 wound around the winding roller 140 rotates; as the endless press-welded belt 118 rotates, its rotation is transmitted to the heating drum 116 by the friction of the endless press-welded belt 118 against the heating drum 116, and consequently the heating drum 116 follows the rotation. That is, the endless press-welded belt 118 is rotated by the winding roller to which the rotating/driving force of the driving source is applied, this rotation is transmitted by the friction of the belt against the drum, and the drum 116 is caused to follow the rotation. Since shearing force is prevented from being caused between the photosensitive material and the image receiving material, both of which are carried while they are held between the endless press-welded belt and the heating drum, slip does not occur between both the materials. Thus, a satisfactory picture free of the occurrence of picture irregularity can be obtained.

IPC: H01L29/84
Filed: 1984-11-27
Abstract: PURPOSE:To constitute the title transducer to an extremely thin type by unnecessitating the height of a pressure introducing pipe and height for preventing the breaking of a tube. CONSTITUTION:Since a pressure introducing pipe 15a is mounted in the direction approximately parallel with pressure-receiving surfaces 11a, 11b in a pressure sensor chip 11, height h4 from a substrate 12 of a tube 22 can be made the same as or smaller than height h1 from the substrate 12 of a cap 15 even when the tube 22 for feeding pressure is inserted to the pressure introducing pipe 15a. Accordingly, the total thickness H of a pressure electric transducer 10 is equalized to height h1 from the substrate 12 of the cap 15 mechanically protecting a mounting section for the pressure chip sensor 11, thus unnecessitating the height h2 of pressure introducing pipes 3a, 7 and height h3 for preventing the breaking of the tube 22.

Title: Diagonal flow impeller
Inventor: MIURA HARUO
IPC: F04D29/28
Filed: 1990-09-21
Abstract: PURPOSE:To reduce the occurrence of a trouble owing to contact of the blade of an impeller with other member, such as a casing, during assembly and disassembly in a state to mount an impeller to a rotor by increasing the outside diameter of the core plate of the impeller to a value higher than the maximum outside diameter of the tip part on the outlet side of the impeller. CONSTITUTION:An outside diameter Da of a core plate 1a of an impeller 1 is increased to a value higher than a maximum outside diameter Db of the end part on the outlet side of a blade 1b. As a result, even in the case of a diagonal flow impeller wherein the impellers 1 are mounted in a multistage on a single rotor 2, a gap (g) is ensured between the blade 1b having low rigidity and other member 8, such as a casing, during assembly and disassembly, and contact is decreased.

Title: Range and tracking radar
Inventor: SUZUKI KEIZO
IPC: G01S13/70
Filed: 1985-11-08
Abstract: PURPOSE:To enchance the secrecy of a radio wave and the electric countermeasure capacity against the jamming of the radio wave, by emitting a wide-band pulse wave subjected to phase modulation based on a zero phase and a pi-phase toward a target and demodulating the wide-band signal from the target to receive the same at narrow-band intermediate frequency. CONSTITUTION:The output of a transmission source 59 is subjected to phase modulation by a third phase modulator 71 using the output signal of a signal generator 75 to obtain a signal which is, in turn, emitted toward a target by a transmission antenna 50 while the reflected wave from the target is received by a receiving antenna 51 and the output of the antenna 51 is applied to a first mixer 62 and a second mixer 63. A signal delayed by the time corresponding to the propagation time from the transmission to the target to the reception from then target by a delay device 74 as compared with the output signal of the signal generator 75 and a signal wherein a value is held as it is in the first half and the value of the first half is reversed in the latter half at every bit of said signal are used to apply phase modulation to the output of a local oscillator 56 by a second phase modulator 82 to obtain a signal which is, in turn, used as a switching signal. By this method, the mixers 62, 63 respectively converts the receiving signal to two intermediate frequencies which are, in turn, amplified by the first and the second intermediate frequency amplifiers and subsequently synchronously detected by a second synchronous detector 67 to obtain a signal. Using this signal, the position of the target is detected.

Title: Eeprom initializing method
Inventor: KAWAMICHI MAKOTO
IPC: G11C7/00
Filed: 1996-09-20
Abstract: PROBLEM TO BE SOLVED: To shorten the initialization time of a mass-storage EEPROM. SOLUTION: A write area of each page of the EEPROM is provided with a management area A. At the initialization, a 1st page is initialized first and its page management area A-1 is set to 'initialization completion'. When a write event of the EEPROM is generated thereafter, information is written to a data area B-1 first. When the page becomes full, the management area A-1 is set to 'writing completion', a next page is initialized, and its management area A-2 is set to 'initialization completion'. Thus, whenever write information is generated, it is written to a data area which is already initialized and a next page is initialized in advance. The initialization time is very short as compared with an information write time, so the initialization time of the EEPROM is only the initialization time of the starting page eventually and greatly shortened.
