Title: Portable apparatus
Inventor: MIYAJI TOMOHIRO
IPC: H04B1/38
Filed: 1997-01-16
Abstract: PROBLEM TO BE SOLVED: To eliminate processing such as removal of burr, assure sufficient strength and eliminate restriction on the fitting position by forming the hand strap fitting part with resin to be inserted and formed to a housing. SOLUTION: A hand strap fitting part 11 is previously formed by flowing plastic resin into a metal die, and this formed hand strap fitting part 11 is inserted to a rear case 10b. Therefore, the process such as removal of burr which is required for the hand strap fitting part formed of a metal material is no longer required and cost reduction can be realized. Moreover, strength of local area of the hand strap fitting part can be improved by using a synthetic resin material which is different from the synthetic resin material of the case for the hand strap fitting part.

Title: Multicore storage tank
Inventor: SHIBAMURA KENTAROU
IPC: F17C3/00
Filed: 1980-01-23
Abstract: PURPOSE:To lower production cost of storage tank by providing a number of division plates between the shell plates of a tank, thus constituting pressure control chambers and by communicating the pressure control chambers to a pressure medium source through a pressure control valve. CONSTITUTION:Pressure control chambers 2 are produced by installing division plates 1 between the shell plates 5 and 8 of a multicore storage tank. The pressure control chambers 2 are communicated to a pressure medium header 19 through a pressure control valve 4. This construction allows the pressure control valve 4 to control the pressure in the pressure control chambers 2 responding to the differential pressure produced therein so that the differential pressure may be minimized. As a result the construction makes it possible to reduce the thickness of shell plates and to fabricate division plates 1 with smaller rigidity and to minimize weld penetration, thereby reducing production cost of storage tank sharply.

Title: Liquid crystal display device
Inventor: SHIMADA KAZUTOSHI
IPC: G02F1/1335
Filed: 1985-01-18
Abstract: PURPOSE:To express display images stereoscopically by laminating polarizing plates, where positions of polarizers are shifted from one another on a plane, in the front of a liquid crystal display element and varying distances from the surface of the liquid crystal display element to individual polarizers. CONSTITUTION:When a voltage is impressed to a liquid crystal layer, corresponding picture elements look black on the surface. Concretely, an image is displayed in the deepest position of a display surface by the polarizer of a polarizing plate 1 out of laminated polarizing plates, and the image is displayed in the front part by polarizers of polarizing plates N.M. Since upper and lower picture elements are different in height in this manner, each picture element has depth information when the image is seen on the plane. Since the density of the coloring matter of a polarizing plate 9 is made highest and the density is reduced successively toward the deepest part, picture elements look deeper gradually and the contrast of the image is reduced gradually toward the depest part when ima- ges are formed continuously from the polarizing plate 9 to the polarizing plate 1; and thus, the displayed image looks more stereoscopic feeling.

Abstract: PURPOSE:To reduce the scale of the circuit of a camera with both remote control and eye-start functions and cost by detecting the outputs of the first light receiving means and a second light receiving means with single detecting means and controlling a camera action based on the output of the detecting means. CONSTITUTION:Remote control signal light emitted from a transmission means 1 is received by the first light receiving means 2.

Filed: 1990-01-17
Abstract: PURPOSE:To prevent the formation of sludge by providing a timer means, a supply passage supplying fresh water and a drain passage discharging fresh water and a residual chemical solution. CONSTITUTION:When the daily working schedule for surface adjustment performed in a treatment tank 53 is completed, a circulation pump 24 for a chemical solution is stopped and, at the same time, a timer 30 is turned ON. When the timer 30 counts a predetermined time and it is estimated that the chemical solution in the treatment tank 53 is almost discharged, the changeover valve 25 on the side of the circulation pump 24 is closed and, next, the changeover valve 36 on the side of a chemical solution tank 22 is closed. At the same time, the changeover valve 38 on the side of a washing pump 46 is opened and the changeover valve 40 on the side of a drain passage 34 is opened. The fresh water sent out of the washing pump washes off a rotary roll 14 and the inner surface of the treatment tank 53 and flows in a discharge port 20 along with the residual chemical solution to flow out to a drain passage 34. By the constitution, the accumulation of sludge can be prevented.

Title: Optical fiber delay equalizer
Inventor: MIZUOCHI TAKASHI
IPC: H04B10/2525
Filed: 1990-01-17
Abstract: PURPOSE:To negate the dispersion characteristics of an optical fiber for transmission with the dispersion characteristic of a dispersion shift fiber and eliminate the influence of the insertion loss and propagation loss possessed by the optical fiber delay equalizer by constituting the equalizer of an erbium-doped optical fiber, an optical coupler and a band-pass optical filter. CONSTITUTION:The optical fiber delay equalizer is constituted of the erbium- doped optical fiber 3, the optical coupler 4 which couples exciting light to the erbium-doped optical fiber 3 and the band-pass optical fiber 5 which shuts off the exciting light and allows the passage of only the signal light. The erbium- doped optical fiber 3 has the characteristics to eliminate waveform distortions by compensating the dispersion characteristics of the optical fiber for transmission and to amplify the signal light by an induction release effect and, therefore, the fiber negates the dispersion of the optical fiber for transmission. The insertion loss and transmission loss of the optical fiber delay equalizer are decreased to a negligible level in this way.

Abstract: PURPOSE:To improve the matching accuracy for processing timing and the error detecting accuracy of the digital sound signals, by detecting and correcting the errors of the digital sound signals recorded with multiplication of frequencies in a reproduction process based on the horizontal and vertical synchronizing signals, a drop-out detecting signal, etc. CONSTITUTION:The errors of the digital data are detected by an error detecting circuit 7 for the digital sound signals subjected to the FM demodulation through an FM demodulation circuit 6. Then the digital data errors are corrected by an error correcting circuit 8 and these corrected data are outputted through a voice terminal 12. If a DT (drop-out) signal is detected by an HD (horizontal synchronization)/VD (vertical synchronization)/DT detecting circuit 9, the detection of an error is decided in preference. Thus this error data is sent to the circuit 7. In such a way, the error detecting accuracy even though the misdetection of errors is caused by the DT signal. In addition, the HD and VD signals inputted to the circuit 8 can be used as the signals showing the position of the digital data on a disk since both signals are synchronous with the revolution of the disk.

Title: Measuring method of surface temperature of glass base material for optical fiber
Inventor: FUCHIGAMI WATARU
IPC: C03B37/018
Filed: 1985-01-21
Abstract: PURPOSE:To measure the surface temperature of a porous glass base material at a specific temperature measurement point at any time by displacing a contactless thermometer according to the growth of a porous glass base material. CONSTITUTION:When glass particulates composed of raw material glass by flame hydrolysis are blown to a rotating seed rod from a burner 1 to grow the porous glass base material 3 for the optical fiber, the contactless thermometer 15 like a radiation thermometer is set so that the center of the flame from the burner 1 is on the surface of the base material 3. Then, the temperature 5 is displaced according to the growth of the base material 3, i.e. increase in its external diameter so as to face a flame contact point where the flame 4 from the burner 1 hits the surface of the base material 3. In this case, the thermometer 5 is moved away from the base material 3 in parallel to the burner 1 as the base material 3 grows. The increase in the external diameter of the base material 3 may be calculated previously from, for example, past data or detected by utilizing the output of a contactless external diameter measuring instrument.
