Title: White signal transmission enable flat-bed scanning type facsimile device
Inventor: TAKEKAWA TAKASHI
IPC: H04N1/04
Filed: 1978-11-13
Abstract: PURPOSE: To realize an easy transmission for the white signal of the flat-bed scanning facsimile by providing the pseduo white area at the fixed position of the beam optical path and then stopping the scanning when the pseudo white area is irradiated.  
     CONSTITUTION: Laser beam 18 generated from laser tube 17 performs the mutual scanning between beams 20 and 22 via scanning mirror 19. Thus the flat-bed scanning is given to transmission original 24 laid flat onto transmission original table 23. The gradation information of original 24 is converted into the electric signals through linear sensor 25 using the PIN photo diode. While secondary scan feed mechanism 26 shifts table 23 toward arror 29 to carry out the secondary scanning. Mirror 19 is driven as shown by arrow 27 to give the reciprocal motion to beam 21. When mirror 19 irradiates pseudo white area 28, the mirror is fixed with the driving current defined to the prescribed value to stop the scanning. In such way, the scanned signal is amplified by amplifier 29 after transmission of the white signal, and the carrier of carrier oscillator 30 is modulated via amplitude modulator 31 to be transmitted to the transmission circuit.

Title: Production of metal composite bar
Inventor: SAKAMOTO MUTSUO
IPC: B23K20/04
Filed: 1990-05-31
Abstract: PURPOSE:To stably and efficiently obtain the top lay type metal composite bar having a good welding state in an edge part by pressing a 2nd metallic bar by using a grooved roll which is specified in the angle formed between the side face and the base and has its groove part of approximately trapezoidal shape in section. CONSTITUTION:The grooved roll 10 which has the groove part of the approximately trapezoidal shape in section continuously in the circumferential direction is used on a steel bar side and a flat roll 12 is used on a copper bar side. The steel bar is pressed by the groove part 14 of the grooved roll 10 and the copper bar is pressed by the flat roll, by which the copper bar and the steel bar are rolled and press welded while the surfaces to be joined thereof are mated. The grooved roll 10 having the groove part which is of 110 to 155 deg. angle formed between the side face and the base is used at this time. The groove part 14 of the grooved roll has such a sectional shape as to sufficiently permit the broadening in the transverse direction. The deformation at the boundary face generated by the restraining of the side face of the 2nd metal bar 42 by the side face of the groove part as is experienced in the case of use of the conventional grooved roll having the rectangular sectional shape is, therefore, prevented. Consequently, the joint strength at the edge part of the 2nd metallic bar 42 is improved.

Thus, in the gear 12, since the transmission of the backward rotation of an output shaft 17 to the mechanism 11 can be cut off by the clutch 13, the  relationship between the operation amount (x) of the stepless speed change gear 10 and  the rotational speed (V) of the output shaft of the clutch, that is, the output shaft 22  of the stepless speed change gear 10 becomes as shown in the figure, and the backward rotation speed change operation region (a) for the gear 12 becomes the operation  region for cutting the transmission. Therefore, if there is any backlash or the like in  the interconnecting mechanism for the gear 10 and the operation device, the state of  the cutting of the transmission of the gear 10 can be effected positively.

Abstract: PURPOSE:To finish the pipe having an optional dimension in optional dimension with high accuracy by putting into a pressure container after tightly closing both ends of the metal tube having a corrugation, increasing or decreasing the pressure inside the pressure container and holding for a fixe time by decreasing or increasing the pressure inside the tube. CONSTITUTION:One part or both parts of a pressure generation devices 6, 7 is actuated to provide a pressure difference P1-P0 on the pressure P1 inside a corrugated metal tube 1 and the pressure P0 of a pressure container 3.

In the case of being at minus value, the waveform pitch is reversely contracted, the outer diameter is made larger and the inner diameter is reduced. The waveform shape can thus be varied by setting the inner and outer face pressures P1 and P0 of the metal tube having a waveform shape and even the metal tube impossible to form by a primary working can be subjected to a secondary working uniformly in the specified dimension.
