Abstract: PURPOSE: To prevent the cracking of a jewel dial plate, by installing the dial plate frame made of the elastic material to the double-sheet dial plate in which the jewel dial plate is adhered on the lower plate of the dial plate.  
     CONSTITUTION: The outer form of the jewel dial plate (d) is made smaller than that of the lower plate (e) of the dial plate. The elastic component (f) such as the plastics, synthetic rubber and the like is put between the outer circumference upper surface of the plate (e) and the bezel (g) to secure a contact between them. Thus the impact given to the wristwatch can be buffed by the component (f). For the concrete structure of the dial plate, the jewel dial plate (d) is adhered to the plate (e) which functions as a reinforcement plate, and several notches (h) are provided to the outer circumference of the plate (e). And the projection (i) is provided to the dial plate frame (f) at the position corresponding to the notch (h). Both the notch (h) and projection (i) are fitted together and then set into the bezel (g). Thus a gap is produced between the plate (d) and the bezel (g) to prevent the cracking of the jewel.

Title: Optical recording and reproducing device
Inventor: ROKUTAN TAKAO
IPC: G11B7/09
Filed: 1990-06-19
Abstract: PURPOSE:To surely protect an actuator by checking a driving current to the actuator at prescribed intervals and cutting off the driving current to the actuator when the number of times that is out of a set range exceeds a prescribed number of times. CONSTITUTION:A difference signal of outputs of photodetectors 13 and 14 is extracted by a subtractor 18 to become a track error signal St, which is then amplified in current by a driving amplifier 19, and the track actuator Ta 21 is driven by this output current via a current detecting resistor 32 through a relay 20. Consequently, when this relay 20 is closed, the device is under the state of a track servo control. Each electric potential of both ends of the resistor 32 is inputted to a subtractor 33 to become a current detecting signal Sc in proportion to the driving current, and this is impressed upon comparators 24a and 24b to compare with comparison levels VHR and VRL, and when it is out of the range limited by these levels, a limit signal H is outputted. The signal H is checked by a CPU 25 for a checking period of time of 1 sec in a period of an interval of 0.01 sec, and when the number of times exceeds a prescribed times of 30 times, it is considered abnormal, and hence the relay 20 is cut off. By this method, burning, etc., of the Ta 21 can be prevented.

Title: Detector for infrared ray
Inventor: DOI SHIYOUJI
IPC: G01J5/28
Filed: 1978-12-28
Abstract: PURPOSE:To remarkably increase the performance of infrared ray detector, by constituting the shape of aperture of cold aperture so that the visual angle viewed from each detection element is equal. CONSTITUTION:When the shape of the aperture of the cold aperture 2 regulating the incident light of the infrared ray detection element array 3 is made narrower at the center and broader at the both ends, then the visual angle to the aperture 2 of each detection element is equal. Thus, the difference of the output signal of each detection element due to the difference of visual angle is avoided and the detection elements of the same sensitivity are located from the center to the both ends. The visual angle from each element can be obtained by using the vertical distance up to the aperture 2 and horizontal distance, and width of the aperture 2 through operation. With this constitution, uniform output signal can be obtained to each detection element and the performance can remarkably be increased.

Title: Halftone phase shift mask, its mask blank, production and defect correction method of halftone phase shift mask
Inventor: TANABE YASUYOSHI
IPC: G03F1/80
Filed: 1997-06-19
Abstract: PROBLEM TO BE SOLVED: To correct defects in a light-shielding film without decreasing the resist pattern transfer characteristics of a halftone phase shift mask by forming an intermediate thin film between a semitransparent phase shift film and a light-shielding film in such a manner that the intermediate thin film has etching selectivity for both of the layers. SOLUTION: An intermediate thin film 3 is formed between a semitransparent phase shift film 2 and a light-shielding film 4. The intermediate thin film 3 has etching selectivity for both of the halftone phase shift film 2 and the light- shielding film 4. When defects 10 are produced in the light-shielding film 4, the defects 10 are removed by using a focused ion beam 11 of Ga ion. By using the focused ion beam 11, damages 13 are produced in the intermediate thin film 3 as the lower layer. However, these damages can be removed at one time when the intermediate thin film 3 is removed by wet etching by a sodium hydroxide liquid. Thereby, the defects 10 in the light-shielding film can be corrected without leaving damages in the mask after correction.

     CONSTITUTION: The standard plate 3 (or subject to be measured) is provided between the radiant ray source 1 and the detector 2. For the output of the detector 2, the voltage proportional to  the thickness (t) of the plate 3 is supplied to the subtractor 8 via the preamplifier 4 and the logarithm amplifier 5. Now the thickness (t) is set to the plate thickness setting unit 6a for the pure- iron standard plate, and the compensation setting unit 6b is set to zero. Thus the voltage T to the  thickness (t) is delivered to the subtractor circuit 7 and the divider circuit 10 from the plate thickness setting unit 7. The value of compensation is obtained through the circuit 10 as N=[(TG-T)/ T]×100 via the subtractor circuit 8 for the output TG of the amplifiers 4 and 5 to the plate 3 having the same material as the subject to be measured and with the known thickness. This value is  then delivered to the indicator 11. In such way, an easy compensation is possible for the material.

Then the word processor performs the KANA/KANJI conversion for the KANA characters and the conversion into the Japanese language for the foreign language characters respectively. Thus it is possible to convert the character strings with a single operation in the same way as a KANA/KANJI conversion system of the word processor.

Title: Automatic air flow direction changeover device
Inventor: NAGATA KOUJI
IPC: F24F1/00
Filed: 1983-09-05
Abstract: PURPOSE:To obtain an automatic air flow direction changeover device excellent in response speed by making up the guide rod of a coil spring of a shape memory alloy from a flat and heat conductive pipe having a number of holes around its circumference. CONSTITUTION:When a room cooling and heating appratus is operated in a heating mode and hot air of a predetermined temperature is blown off, a coil spring 17 made up of a shape memory alloy is heated above the transformation temperature, the coil spring 17 elongates. The guide rod 12 is formed into a flat shape and a number of holes 12' around its circumference, and hence has a small heat capacity. Furthermore, the long side of the guide rod 12 is arranged so that it becomes parallel to the wind direction. Hence, the device is well ventilated, and the coil pring 17 is heated rapidly and uniformly, and elongates in a short time. As a result, a variable vane 9 inclines downwardly in a short time and hot air is blown off downwardly. When the heating operation is stopped or when the cooling operation is carried out, the coil spring 17 is cooled below the transformation temperature and assumes a compressed state, and the variable vane 9 inclines front-upwardly and cool air is blown off toward that direction.
