Abstract: PURPOSE:To restrict a shadow mask from cooling rapidly so as to hold the initial tensile strength by performing a stabilization processing of the shadow mask structure prior to application of black lead and phosphor while putting the shadow mask surface in a close contact with a flat plate having a higher heat capacity than that of the mask. CONSTITUTION:Before being subjected to stabilization processing prior to application of black lead and phosphor a shadow mask 2 has its flat surface brought in close contact with a flat plate 5, to be fixed with a fixing jig 6. For this flat plate 5, a plate having higher heat capacity than that of the shadow mask 2 such as the one made of SUS 304 with 3mm in thickness should be used. Then, the shadow mask structure is set in the prescribed plate in a panel 4 by preparing a spring 3 fitted to a stud pin 7 mounted within the panel 4. Under this condition, the shadow mask structure and the panel 4 are heated in the atmosphere at 430 deg.C for 60min as stabilization processing, and later cooled gradually with practically no change imposed on tensile strength of the shadow mask 2. Then, after being removed from the panel 4 and then from the flat plate 5, the shadow mask structure has its surface applied with black lead and phosphor.

Title: Wafer flatness measuring equipment
Inventor: ISHIMORI HIDEO
IPC: H01L21/66
Filed: 1999-02-15
Abstract: PROBLEM TO BE SOLVED: To suppress the effect of mechanical oscillation noise by arranging a specified number of optical sensors in the subscanning direction orthogonal to the main scanning direction thereby obtaining a plurality of measurements of same point during single inspection. SOLUTION: The wafer flatness measuring equipment comprises an optical heterodyne interference measuring unit including a CCD line sensor 33 having n (n>2) pixels as a photosensor on the measuring light side. A wafer 1 mounted on an Rθ table 2 is then subjected to spiral scanning for duplicating scanning of the track of n-1 pixels being subscanned in the direction R at a pitch corresponding to 1 pixel. From the measurements of respective detection pixels of a line sensor 33 stored on a data table 12e, an average value is calculated for the identical detecting position of n pixels being obtained during n-th and subsequent circulations. Since the measuring period at an identical measuring point corresponds to several Hz corresponding to the r.p.m. of the wafer, for example, low frequency noise of mechanical vibration, and the like, can be removed.

Title: Heat treatment device of high molecular material
Inventor: ISHIHARA HIDEAKI
IPC: B29B13/02
Filed: 1984-02-27
Abstract: PURPOSE:To enable heating speed to be heightened without applying mechanical stress to high molecular material by a method in which the heating medium gasified by preheating is caused to be in contact with high molecular material and is condensed, and then it is heated by microwave induction heating. CONSTITUTION:A heating medium is heated by a heater 8 and becomes gaseous heating medium 7b, and then is blown to high molecular material 2 through a blowing nozzle 9 by way of a gas flowing device 11. Because the temperature of the high molecular material 2 adjacent to the inlet of a preheater 6 is low, when the gaseous heating medium 7b is in contact with the high molecular material 2, said medium 7b is condensed, and heightens the temperature of the high molecular material 2, giving its condensation heat to said material 2. The preheated high molecular material is moved to a microwave heater 12 at the state where the condensed heating medium 7c has adhered to its surface, and is heated to the temperature of heat treating operation. Simultaneously, the heating medium 7 adhering to its surface is removed by evaporation. Because the value (epsilonrtandelta) of the high molecular material 2 is sufficiently large by preheating, it is effectively heated in short time by microwave.

Title: Signal pick up device
Inventor: KOBAYASHI SHIGEMASA
IPC: G11B3/50
Filed: 1985-02-25
Abstract: PURPOSE:To absorb a distortion caused by a cartridge case and the like and a distortion due to an error in attaching a leaf spring support member by a coil spring and make a stable control operation possible by supporting an end of the leaf spring support member supporting a cantilever by a coil spring and applying constantly a fixed tension. CONSTITUTION:An end of a support member supporting a cantilever is fixed to an end of a coil spring. When a force T from an outside is applied to a cartridge case 6, a connecting section A of a support member and a coil spring is changed to a position of A'. Since a vertical stiffness Ks with respect to the cantilever 2 of the support member 5 is considerably largely set in comparison with the stiffness Kc of the coil spring, the stiffness Ks is substantially fixed and the external force T is absorbed by a change of the coil spring. In this manner, a distortion by an external force is absorbed by a coil spring, so that an influence applied to an axial control operation in a direction of the cantilever 3 is scarcely present.

Title: Reflector for focus of sunlight
Inventor: UEMOTO HIROSHI
IPC: F24S23/70
Filed: 1981-03-11
Abstract: PURPOSE:To obtain the hot water of a high temperature with a reduced loss of heat, by fixing a reflector having a curved surface that increases the density of the sunlight by several times plus a heat collector from the summer solstice through the winter solstice. CONSTITUTION:The curved surface of a reflector 8 starts at point P adjacent to a heat collector 7. For the inclination of the surface at the point P, if the utmost edge beam among the beams striking on the point P, i.e., the tangent line of the point P hits on the collector 7, all other beams hit on the collector 7. In this connection, the surface at the point P is set at right angles to the tangent line passing the point P. For instance, the beam that reflected at point K is made to  hit on the point P. Then the curved surfaces passing points A, B, C and so on  are formed in the same way. In such way, the density of the sunbeam can be increased by several times while the reflector 8 and the collector 7 are fixed as they are.

Title: Recording device for video signal
Inventor: YAMAZAKI MINORU
IPC: G11B5/592
Filed: 1985-02-25
Abstract: PURPOSE:To obtain sufficient reproduction pilot signals even in the case of small track deviation by equalizing a reproducing section to a recording section regardless of the length of track deviation. CONSTITUTION:When a pilot signal SP1 is recorded on the first track T1 by the first head H1, the pilot signal SP1 is reproduced on the adjoining second track T2, and when a pilot signal SP2 is recorded on the fourth track T4 by the second head H2, the pilot signal SP2 is reproduced on the adjoining fifth track T5. Accordingly, pilot signals SP1, SP2 recorded on the first and fourth tracks T1, T4 can be reproduced over the whole recording section WR'. Thus, a sufficient pilot signal reproducing section can be secured even when a track deviation TX is very short, and a driving voltage sufficient to drive an electrostrictive element can be formed irrespective of the length of track deviation TX.

Filed: 1986-02-20
Abstract: PURPOSE:To obtain a small-size, low-cost, highly reliable and thermally controllable by detecting the temperature of a ceramic member using a temperature- sensitive element and thereby controlling a heating element. CONSTITUTION:A compressed ink is supplied to an ink liquid chamber 5 in a head body 1 consisting of ceramic material, and an ink pressure is applied by the distortion of an electrostrictive oscillator 4 on an oscillation signal applied to the electrostrictive oscillator 4. This injects ink through a nozzle outlet. The large diameter section 1B of the head body 1 has a heating element printed in thick film on the ceramic surface, and the A section represents a printed pattern in conductive paste indicating an installation pattern of heater terminal and thermistor. In the meantime, the B section represents a heater pattern region, and the C section has a chip thermistor soldered which detects the temperature of a heated ceramic body. The thermistor is installed in such a way that a temperature difference of ink at a heater and a nozzle outlet may equal the temperature difference at the heater and the thermistor. Under this arrangement, it is possible to make ink temperature constant by controlling thermistor-detected temperature at constant level.
