Title: Diaphragm of speaker
Inventor: ISOGAI TAKESHI
IPC: H04R7/02
Filed: 1978-06-21
Abstract: PURPOSE:To form the carbon matrix diaphragm with omission of the repetitive working for the impregnation and burning in the manufacture processes by depositing the heat decomposed carbon on the carbon fiber filament of the base material and thus filling up the filament gap with the heat decomposed carbon. CONSTITUTION:The resin such as the acryl phenol polyimide rayon, PVA, vinyl chloride and the like is burnt and carbonaed in the inactive atmosphere and at about 450-1650 deg.C to obtain the carbon fiber. This carbon fiber is molded into the shape of the desired speaker diaphragm to obtain the base material, and this base material is heated up to about 1000 deg.C or higher in the organic gas such as the methane gas or the like. Then the heat decomposed carbon liberated from the organic gas is deposited on the carbon fiber filament to be used as the base material to fill up the gaps between the carbon fiber filaments. In this method, no contraction is caused in the burning process, and the accuracy control can be facilitated for the trim size. As a result, the maufacture can be facilitated for the matrix diaphragm.

IPC: H04N1/04
Filed: 1988-03-31
Abstract: PURPOSE:To omit such a case where a reading part set at the reading end position is moved back to the reading start position and to shorten the time used exclusively for a circuit by using a transmission control means which transmits image data received from the reading part after rearranging them in the order decided by a deciding means. CONSTITUTION:A decision means decides the position of a reading part 3 and then a determining means determines the subscanning direction of the part 3 according to the position of the part 3. At the same time, the determining means determines the transmitting order of the image data received from the part 3 and informs the subscanning direction to a drive control means and the transmitting order to a transmission control means respectively. The drive control means moves the part 3 in the direction determined by the determining means and the transmission control means transmits the image data received from the part 3 after rearranging them in the order determined by the determining means. As a result, the part 3 can subscan to read the originals regardless of its moving direction and it is not required to move the part 3 back to a reading start point A from a reading end point B. Therefore, the time of communication is shortened.

Title: Control circuit
Inventor: NAKAGAWA SHIYOUICHI
IPC: H03G3/10
Filed: 1982-05-08
Abstract: PURPOSE:To eliminate the temperature dependance for an output signal when no control signal exists, by forming a simple circuit with plural transistors (TR), etc. to obtain an output signal by which controlling an input signal. CONSTITUTION:The base potential V1 of a TRQ1 is set at V1; while TRs Q2, Q5 and Q6 have V2 base potential respectively. At the same time, the collector currents of TRs Q3 and Q4 are set at I3 and I4 respectively. When the control signal is set at a non-signal (V1-V2)=0, it is possible to set I4/I3=1/n (R2/R1) at a fixed value. The value (R2/R1) has no temperature dependance, and therefore I4/I3=1/n (R2/R1) has no temperature dependance either. The values R1 and R2 can be set from the request for sensitivity of a desired control signal. If the same value is selected for both R1 and R2, I4/I3=1/n is obtained. As a result, the temperature dependance can be ignored totally for the resistances R1 and R2. Thus a fixed value can be held for a control circuit with no temperature dependance at all.
