Title: Fusion-bonding method for synthetic resin member
Inventor: SAITO JUN
IPC: B29C65/08
Filed: 1993-03-31
Abstract: PURPOSE:To reduce burrs extended from an outer surface via two stripes of melting margins and to improve reliability of a fusion-bonded part by opposing surfaces to be fusion-bonded of synthetic resin members in a flange state and providing two stripes of parallel ribs at least at one of the surfaces as a melting margin. CONSTITUTION:Flanges 3, 4 are provided at synthetic resin members 1, 2, and two stripes of parallel ribs 7, 8 are provided at one of opposed flat surfaces 5, 6. When it is pressed to be vibrated, burrs also flow to a recess 15 between the ribs 7 and 8, and hence burrs externally extended are reduced. Since fusion- bonded parts are formed in two stripes, reliability of pressure resistance and airtightness is enhanced.

Inventor: ZAITSU TOSHIYUKI
IPC: H02M1/00
Filed: 1992-04-20
Abstract: PURPOSE:To prevent overvoltage from occurring upon throw-in of input voltage. CONSTITUTION:The voltage detecting circuit 1 comprises resistors 11, 12 for dividing an output voltage 102, a shunt regulator 15 receiving voltage across the resistor 12, and the load of the shunt regulator 15, i.e., a photocoupler 13 and a resistor 14.

Title: Very small current amplifier circuit and color identification sensor circuit using it
Inventor: FUJIMOTO KIMITADA
IPC: H03F3/343
Filed: 1996-03-27
Abstract: PROBLEM TO BE SOLVED: To obtain an input output characteristic with an excellent current conduction even in the case of a very small input current or of presence of a temperature rise by compensating a leakage current caused in a semiconductor element from which an output terminal is led out so as to eliminate the effect of a leakage current caused by an element structure in the current conduction circuit. SOLUTION: A current conduction circuit 4 is made up of a current mirror circuit and a leakage current compensation circuit 5 is made up of a mirror circuit. In the case that a same component is adopted for a TR Q2 of the current conduction circuit 4 and a TR Q4 of the leakage current compensation circuit 5, a leakage current produced in each collector is identical. Thus, the leakage current produced at a collector of the TR Q2 is cancelled by giving the leakage current produced at the collector of the TR Q4 to the collector of the TR Q2 through the mirror circuit consisting of TRs Q5, Q6 of the leakage current compensation circuit 5. Thus, an error in the input output characteristic is eliminated.

Title: Axial blower furnished with bell mouth
Inventor: KANESHIRO SUEO
IPC: F04D29/56
Filed: 1994-05-13
Abstract: PURPOSE:To make air capacity comparatively large in a large air capacity range, to make static pressure large in a small air capacity range and to make a characteristic curve concave dropping to the right without lowering efficiency. CONSTITUTION:On the inside of a casing 1, a bell mouth 2 having a curvature 2a the inside of which is smooth in the discharge direction is arranged.
