Title: Tension distribution measuring method
Inventor: MATSUBARA TOSHIRO
IPC: G01L5/04
Filed: 1993-02-25
Abstract: PURPOSE:To allow accurate measurement of tension distribution by calculating a tension distribution under a desired temperature distribution based on the distribution of uniform tension and the magnitude of thermal expansion or contraction. CONSTITUTION:Value of uniform tension is determined according to a formula representative of relationship between the oscillation frequency of 1-1st order oscillation mode and tension per unit crosssectional area. Tension distribution for a predetermined value of temperature distribution is then determined according to a predetermined calculation formula derived from a uniform tension formula. The calculation formula includes coefficient of linear expansion, Young' s modulus, Poisson ratio, dendity, thickness of a band material 1 and the distance between rolls 2a, 2b. When they are given, tension distribution under desired temperature distribution can be determined by measuring the temperature distribution and oscillation frequency under 1-1st order oscillation mode of heated band material 1. Since the value of uniform tension is determined and thermal expansion or contraction is corrected based on the value thus determined, tension distribution can be determined accurately.

Inventor: AIZAWA HIDEO
IPC: G03G15/16
Filed: 1990-02-20
Abstract: PURPOSE:To prevent void phenomenon which is generated at the trailing edge of transfer paper by turning off a before-transfer destaticizing means at the time that the position, which is supposed to be at a transfer position at the time when the transfer paper trailing edge passes through the noncontinuous part of guide members, on the photosensitive body passes through the operating position of the before-transfer destaticizing means. CONSTITUTION:The before-transfer destaticizing means 10 is turned off at the time that the position, which is supposed to be at the transfer position at the time that the transfer paper trailing edge passes through the noncontinuous part of the guide members 13 and 15, on the photosensitive body 1 passes through the operating position of the before-transfer destaticizing means 10. Therefore, when the before-transfer destaticizing is performed, an image part on the photosensitive body 1, which corresponds to the range which has the transfer paper trailing edge where the separa tion electric discharge is generated by vibration caused by permitting the transfer paper trailing edge to pass through the noncontinuous part of the guide members 13 and 15, it not destaticized before the transfer. Thus, the separation electric discharge is not generated by small vibration and an excellent image without a void at the transfer paper trailing edge part is obtained.

Title: Method for protecting memory for individual identification
Inventor: KONDO SHIRO
IPC: G01S13/78
Filed: 1988-02-22
Abstract: PURPOSE:To prevent the occurrence of a case where the data of a salve station cannot be regenerated by applying a protect to a memory when the slave station receives a protect command from its host station and cancelling the protect only when the slave station receives a protect cancelling command from the host station. CONSTITUTION:When the command sent from a host station instructs data readout, a slave station fetches necessary data from a memory 5 and sends the data to a MODEM 2 where the data are modulated. The modulated data are transmitted to the host station through a transmission-reception antenna 1. When the command from the host station instructs rewriting of data, a CPU 3 first refers to a memory rewriting inhibit flag 4 and, when the flag 4 indicates that memory rewriting is not inhibited, the CPU 3 performs a process which writes successively sent data in the memory 5. On the other hand, when the flag 4 indicates that memory rewriting is inhibited, the CPU 4 ignores the memory rewriting command and protect the memory 5 by throwing away the data sent thereafter after a single reading.

Title: Voltage controlled oscillator
Inventor: HIKITA JIYUNICHI
IPC: H03B5/12
Filed: 1984-02-28
Abstract: PURPOSE:To obtain a constant oscillating frequency at all times independently of a power voltage by providing a current generating circuit giving an operating current depending on fluctuation of a drive voltage to a control input circuit even when a power voltage is fluctuated and the control input circuit has an offset. CONSTITUTION:An output current I is made dependent on a power voltage Vcc by flowing a current to a constant current source circuit of a current generating circuit 12 via a resistor 176 from a drive power supply and the fluctuating component of the power voltage Vcc is given to a control current DELTAI outputted from a control input circuit 8. When the current I is given only with the current I2 only from the resistor 176 and the value I is I=2I2, the value of the current I depends on the change in the power voltage Vcc and the output current DELTAI of the control input circuit 8 changes with the power voltage Vcc. As a result, the output frequency fO to the power voltage Vcc is as shown in characteristics (a), (b) in Fig. Then the current I is formed by adding the current I1 being the constant current output of the current generating circuit 12 to the current I2 depending on the power voltage Vcc and the ratio is set as I1=I2, the fluctuating component of the power voltage Vcc to the constant current component is added to the control current DELTAI, resulting that the oscillating frequency fO to the power voltage Vcc has a flat characteristic.
