Title: Observing apparatus for end face of optical fiber
Inventor: YAMAUCHI KENJI
IPC: G01N21/88
Filed: 1991-07-31
Abstract: PURPOSE:To easily detect a foreign matter adhered to the end face of an optical fiber by sinking the optical fiber into a solution of the same refractive index as the optical fiber, and applying light from outside of a container. CONSTITUTION:A solution 2 of the same refractive index as an optical fiber 1 is filled in a transparent container 3. The optical fiber 1 is put in the solution. The light is applied by a light source 4 from outside of the container 3. At this time, since the solution 2 has the same refractive index as the optical fiber 1, only a foreign matter of a different refractive index adhered to the optical fiber 1 reflects the illuminating light. Therefore, it is not necessary to apply the light at right angles to the end face of the optical fiber 1. The foreign matter can be easily detected even when the light is applied from any direction.

CONSTITUTION:A spacer 2 is sandwiched between filter membranes 1 and 1' and a space layer is formed. The assembly is wound on a cylindrical porous carrier 5. Although the desired number of layers can be formed in the filter part, two layers are usually formed. A microporous membrane made of a resin is used as the membrane filter, the thickness is preferably regulated to 20-200mum and the mean pore diameter is controlled to 0.01-20mum. The pore diameter on the inlet side 1 of a fluid to be filtered is preferably made smaller than that on the outlet side 1'. The porous spacer is provided with many pore- like spaces and furnished with flexibility sufficient to be sandwiched between the membranes to form a filter element. The decrease in the distance between membranes when pulse pressure is exerted is maintained preferably at <=50% by the spacer.

Title: Control circuit for variable gain amplifier
Inventor: ITOBAYASHI MANABU
IPC: H03G3/10
Filed: 1982-10-27
Abstract: PURPOSE:To remove the temperature characteristics of a variable gain amplifier by obtaining control voltage for cancelling the temperature characteristics of differential voltage from reference voltage which is the output voltage of a control circuit for the variable gain amplifier. CONSTITUTION:A starting circuit 9 operates only at a moment turning on a power supply and drives a current mirror circuit 30. The collector current of a transistor (TR) 11 flows into a diode 12 through a resistor R2 and drives a current mirror circuit 40. A TR 13 drives a diode 10 in stead of the starting circuit 9 to actuate the circuit 30. Thus, the circuits 30 and 40 have the relation driving each other and forms a positive feedback loop to turn to stable status. The gain G of the circuit is expressed by the shown formula and the temperature characteristics may be included by the h (=kt/q) term. When conditions such as a transistor (TR) 13 and a diode 12 are used for calculation, the h (=kt/q) term is erased. Thus, the temperature characteristics of the gain Gv is removed, so that the temperature characteristics of the variable gain amplifier are also removed.

Filed: 1983-10-12
Abstract: PURPOSE:To make effective use of displayed picture face by enlarging and displaying picture information in a display section when the size of a picture of the information is smaller than the display face of the display section. CONSTITUTION:When a switching signal SW is at H level, that is, when making enlarging of a picture signal, AND gates A3, A4 become H level output when detectors C1, C2 output a carry detection signal. At this time, gates A1, A2 stop to transmit clocks CL1, CL2 to a driving circuit 81. Accordingly, when detectors C1, C2 have outputted carry detection signal, clocks CL1, CL2 are not inputted to the circuit 81, and no picture signal is outputted from the circuit 81. However, gates G2, G4 are opened and the data of immediately before storage in a 1 bit buffer BF are outputted through an OR gate O1, and data of 1 line before storage in a line buffer LB are outputted through an OR gate OA. That is, the picture signal is outputted doubly, and the picture is enlarged, for instance 1.25 times, in horizontal and vertical directions.
