Title: Automatic gain control amplifier circuit
Inventor: KOMORI HIROSHI
IPC: H04N5/52
Filed: 1993-12-27
Abstract: PURPOSE:To automatically conduct gain control and to obtain simple circuit size by preparing a control circuit for changing control voltage by the intensity of a signal inputted to an input terminal. CONSTITUTION:When no signal is inputted to input terminals 5-1, 5-2, the bases of transistors (TRs) Q11 to Q13 are set up to the same potential and respective collector currents are equalized. When small signal AC voltages UO, -UO having mutually reversed phases are impreseed to the terminals 5-1, 5-2, small signal AC currents are allowed to flow into the collectors of the TRs Q11, Q12 and their synthetic current is superposed to a resistor R11. Since the DC component of the synthetic current always has a positive value, control voltage V1 is reduced as compared with a case inputting no signal to the terminals 5-1, 5-2. Since control voltage V1-V2 is changed within a positive range by the intensity of the signals inputted to the terminals 5-1, 5-2, the gain of a differential amplifier circuit part is automatically controlled.

Abstract: PURPOSE:To easily confirm the content of an original without use of a facsimile equipment by providing a processing section extracting a character data corresponding to a designated reception number from a storage section with the external designation of the reception number and inputting the data to a conversion section to the equipment. CONSTITUTION:A storage and decoding section 20 converts part (index) of a facsimile transmission original data into a character data and stores the data to a storage section 14 while corresponding the data to the reception number for each transmission of one original. A character data corresponding to the reception number designated from the storage section 14 under the control of a processing section 11 and the character data is converted into voice information by a conversion section 15 and outputted. When a sender having made, e.g. facsimile transmission confirms the content of the original sent by the sender from a visit place or the like and the sender designates the reception number by using the telephone set at the visit place, the content of the original sent by the sender is heard from the telephone set as a voice. Thus, the content of the original is easily confirmed without printing out on its facsimile equipment.

Title: Combustion of oil coke unburnt dust and its device
Inventor: FUJII KENICHI
IPC: F23G5/04
Filed: 1988-12-28
Abstract: PURPOSE:To make a noncombustible component of high purity to collect vanadi um by burning dry powder of dry-treated oil coke unburnt dust in a combustion and fusion furnace to recover fuel energy as steam and making unburnt ash slag contain a large quantity of vanadium. CONSTITUTION:Dehydrated cakes of an oil code unburnt dust are supplied in a flash drier 1 by the use of combustion exhaust gas from a boiler to be dry-treated and make dry powder. The dry powder is carried by air in a combus tion and fusion furnace 16 to burn and melt to introduce high temperature combustion gas in the boiler 8 so as to produce steam. In the combustion and fusion furnace 16, auxiliary fuel such as oil or gas fuel is used in 5-40% of the whole because ignition flame stabilizing is ensured. In the furnace 16, combus tible components becomes CO2 and H2O by combustion reaction and noncombusti ble ash becomes melting slag. Vanadium concentration in the collected slag is high and its effective utilization as a raw material for recovering vanadium is made possible because the unburnt component is scarcely mixed with the slag.

CONSTITUTION:The illuminating luminous flux 2 emitted from the light source 1 is in a non-polarized state and is separated to reflected S polarized light 30 and transmitted P polar ized light 33a by the joint surface 20a of a polarizing and separating means. The reflected S polarized light is made incident on a polarizing rotating means 21. The S polarized light 30 made incident on the polarizing rotating means is emitted as the P polarized light 31, transmitted through the means 20 still as the P polarized light, reflected by an optical path conversion means 23 and passes through a condenser lens 10 as the linearly polarized light 33b in the same polarizing and advancing directions as those of the transmitted P polarized light 33a to be made incident on the liquid crystal light valve 3. The axis of polarization is arranged on the incident side polarizing plate 8 of the liquid crystal light valve 3 so as to conform with the direction of the incident linearly polarized light 33a and 33b. As a result, light energy which is about twice as much as in conventional practice is made incident on a liquid crystal layer and contributes the image display.

Title: Stamping instrument
Inventor: KAWASAKI MASAYUKI
IPC: B41K1/32
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To restrain the faulty discharge due to insufficient or excessive discharge of ink as well as the leakage of ink by a method wherein an air passage, communicated with the ink receiving unit of a main body, is formed so as to be bent type air passage while a porous wall is arranged on the air passages. SOLUTION: A porous wall is formed at a part, against which the fore end face of engaging part 9 of a main body 1 is abutted, while a plurality of venting holes 10a are formed in the porous wall. The part of a mounting hole 7, whereat the porous wall is formed, is a part whereat the main body 1 is engaged with a handle 3 and is a comparatively wide spatial part among the air passages. Accordingly, even when ink has invaded into the air passages, the movement of the ink can be stopped since the space is a wide space wherein capillary force is not applied comparatively before the ink leaks to the outside equipment. Even when the ink has moved further, the porous wall is formed whereby ink film is formed by the strong capillary force of the vent holes 10a to restrain the movement of the ink thereby permitting the prevention of leakage of the ink.

Abstract: PURPOSE:To prevent completely a defect due to solder flow by packing a resist layer able to be removed by melting in an air gap in advance and removing the resist layer with melting after the end of the electric connection process of a piezoelectric vibrator onto an insulation board. CONSTITUTION:A resist layer 21 able to be removed by melting in advance is packed in the gap S used to attain the vibration of the piezoelectric vibrator 11 and the electric connection of the piezoelectric vibrator 11 onto the insulation board 14 is applied in this state.
