Patent JP-H0232308-A (JP)
Title: Coated optical fiber
Inventor: HOSOYA TOSHIFUMI
IPC: G02B6/44
Filed: 1988-07-21
Abstract: PURPOSE:To maintain the adhesive property between an optical fiber and a coating layer over a long period of time even if the optical fiber is used in the state of being immersed in a waterproof intimate mixture by incorporating an oil component used for the waterproof intimate mixture into the protective layer. CONSTITUTION:The protective layer 3 contains the coil components used for the waterproof intimate mixture. An effect arises from a very small ratio of the oil component to be incorporated into the protective layer 3 and the ratio at which a marked effect is admitted is >=0.1%. Although the oil component exhibits the effect if said component is incorporated in the state of being dissolved in the protective layer 3, said component is not always required to be dissolved and may be equally satisfactorily incorporated into the protective layer in a uniformly dispersed state. In general, however, <=3% is adequate. The transfer of the oil component in the waterproof intimate mixing agent into the protective layer 3 does not take place even if the component is used in the state of immersing the optical fiber in the waterproof intimate mixing agent and, therefore, the adhesive strength between the optical fiber 1 and the coating is maintained over a long period of time.

Title: Microscope
Inventor: HASEGAWA HISASHI
IPC: G02B21/26
Filed: 1996-07-10
Abstract: PROBLEM TO BE SOLVED: To make a user feel fatigued little and possible to keep material posture even in the case of long-time observation, by arranging a focusing handle and a stage handle at right and left symmetric positions with respect to a mirror body. SOLUTION: When a fine adjustment handle is turned, a coupling shaft 12 is rotated. The rotation of the shaft 12 makes a stage 39 move up and down by a very small amount. When a coarse adjustment handle is turned, the stage 39 is coarsely adjusted. The focusing handles 31A and 31B operated with both hands and the stage handle 22 are arranged at the same height and symmetrically with respect to the mirror body 32. Thus, an abserver can observe in the more natural posture without turning his body than in the case of the conventional microscope. Then, the fatigue in the case of the long-time observation is made little. Furthermore, in the case of focusing operation by the fine adjustment, it is posible to operate the fine adjustment handle on the stage handle 33 side.

Abstract: PURPOSE:To facilitate realizing excellent characteristics and a high speed operation by forming a gate electrode with material containing mixture of GaMo3 and Mo5As4 at least on the side of a semiconductor substrate or a semiconductor layer. CONSTITUTION:A film made of, for instance, Mo is formed on a semiconductor layer 4 so as to form a Schottky barrier 6 between the semiconductor layer 4 and itself and subjected to reactive ion etching to form a heat-resistant metal film 5.

Abstract: PURPOSE:To increase the ratio of area of an emitter to occupy in a unit pattern, and to isolate effectively respective emitter regions by a method wherein the island type emitter regions of the plural number are so constructed as to be connected mutually at the part of the prescribed depth from the surface of a base region. CONSTITUTION:Although the P-N junction 17 of an emitter region 16 and a base region 13 positions at the place connecting the equal impurity concentration points of both the regions 13, 16, because the equal concentration face 19 of the emitter region 16 forms a circular arc type at the outside of the edge part of an opening 11 in contrast to the equal concentration face 18 of the base region 13 forming flatness at the part other than the circumferential part of the base region 13, the emitter region 16 is expanded much more in proportion to depth of the low concentration region of the profound part, and the P-N junction 17 has the shape having the broader expanded bottom than the surface part. Because the interval between the two openings 11 is selected narrowly, the two emitter regions 16, 16' are connected at the profound part to be integrated in one body in the shape. Nevertheless because the connecting part 20 of both is the low concentration region, and acts as the resistance component, it effects interposition of resistance RB between the two emitter regions 16, 16', and is enabled to act as isolation resistance to isolate between the emitter regions 16, 16'.

CONSTITUTION:A laser beam which has been emitted by an optical part 11 is irradiated to a bar-code which has been recorded in a label 2, and a reflected light of that time is inputted to an A/D converting part 12. The A/D converting part 12 reads this reflected light, converts it to a digital signal and sends it out to a demodulating part 13 and a logging processing part 3. A control part 31 of the inside of the logging processing part 3 records this signal in a floppy disk (FLP) 6, and also demodulates this signal. On the other hand, the demodulating part 13 also demodulates an input signal and transfers it to the control part 31. The demodulated data are compared with the data which has been demodulated by the control part 31 itself, and by its result, the function operation of the demodulating part 13 is confirmed.

Abstract: PURPOSE:To provide a control method of a sub path solenoid valve having a function of delivering hot water immediately by improving hot water delivery characteristic at the start of delivering hot water or at the redelivery of hot water under various conditions. CONSTITUTION:In a water heater, an allowable maximum flow rate Qmax of the amount Q of water intake is calculated based on a set temperature tS, the temperature TC of the water intake and the maximum heating capacity of a heating means to control a water quantity control valve so that the amount Q of the water intake does not exceed the allowable maximum flow rate Qmax. At the start of supplying hot water, the amount Q of the water intake is set at an initial amount Q1 of passing water smaller than the allowable maximum flow rate and the amount Q of the water intake is increased to the allowable maximum flow rate after the passage of a standby time T set variably in proportion to a deviation between the set temperature tS and the temperature tC of the water intake. Moreover, in the start of redelivering hot water during a post purge, the standby time during the post purge is calculated based on T. Thus, the redelivery of hot water is started at a small flow rate and the flow rate is increased at a proper standby time thereby enabling stable delivery of hot water without being affected by changes in conditions of delivering the hot water containing length or shortness of the time of stopping the delivery of the hot water.
