IPC: G02B6/02
Filed: 1998-10-12
Abstract: PROBLEM TO BE SOLVED: To easily manufacture a product which has a desired reflection attenuation factor at low cost without using a special member or special machining technology by inserting a coreless fiber which has nearly the same refractive index with that of the core of an optical fiber into a ferrule main body and machining an end surface of the ferrule main body into a convex spherical surface. SOLUTION: The coreless fiber 10 is made of quartz glass, etc., and has nearly the same refractive index with that of the core part of the optical fiber on the whole. The coreless fiber 10 is inserted into the center hole of the standard ferrule main body 11 made of zirconia and fixed with an adhesive. Further, the tip part 12 of the ferrule 1 constituted by inserting the coreless fiber 10 into the ferrule main body 11 is formed into a convex spherical surface. This manufacturing technology is equivalent to the technology that an ordinary optical fiber is inserted into a ferrule and polished and neither a special tool nor special machining technology is needed to lower the manufacture cost. Further, polishing for removing a hard layer is performed in end surface machining to secure a >=40 dB reflection attenuation factor quantity.

Title: Self-excited inverter
Inventor: SHIMOKAWA KAZUTO
IPC: H05B44/00
Filed: 1996-10-31
Abstract: PROBLEM TO BE SOLVED: To eliminate the distortion of a dynamic wave which is caused by a capacitive load and improve the conversion efficiency by a method, wherein a ripple component current which is returned to a DC power supply is made to bypass a 2nd capacitor which is connected in parallel to a 2nd resistor connected between a 1st resistor and the DC power supply. SOLUTION: If most part of an input voltage Vin is applied to the primary winding of a transformer 6, a counter charging current is applied to a capacitor C1 by the induced voltage of a feedback winding. If the counter charging current is applied to the capacitor C1 , the base potential of a transistor Q1 drops and an input current Iin' starts to drop. At that time, since the current supply to a DC power supply 1 side is limited by a resistor R11 , the drop in the base potential of the transistor Q1 is avoided. Further, a current applied to the DC power supply 1 side through a resistor 11 is supplied to a parallel circuit, consisting of a resistor R1 and a capacitor C11 and is made to bypass the capacitor C11 and supplied to a DC power supply 12 side. Hence a current flowing through the resistor R1 can be reduced.

Title: Evaporator for ice heat storage type heat exchanger
Inventor: UNO HARUZO
IPC: F25C1/00
Filed: 1998-09-29
Abstract: PROBLEM TO BE SOLVED: To uniformize the thickness of ice attached to each portion of a water tank, by making the spiral pitch of a pipe larger at a refrigerant entrance side than at an exit side, in an evaporator for an ice heat storage type heat exchanger in which the pipe for flowing refrigerant therethrough in a state of two layers of liquid and vapor, is spirally wound in a cooling water tank. SOLUTION: A pipe 2 for flowing refrigerant therethrough has a spiral form which is entirely cylindrical, in an evaporator for a heat exchanger which serves as an ice heat storage type beverage dispenser. An entrance 4 is formed at the tip of a spiral portion which is located at the uppermost end, and an exit 5 is formed at the tip portion which is bent upward from the lowermost portion. The temperatures of the refrigerant and cooling water are lower at a higher level, and therefore, ice is more easily formed at a higher level. Specifically, the pitches of the spiral pipe 2 at the individual stages, i.e., pitches P1-P4 from the upper to the lower, respectively, are formed so as to be P1>P2>P3>P4. Therefore, formation of ice at the upper portion is suppressed. Thus, ice 6 takes a spiral form which is substantially uniform from the upper to the lower.
