Title: Recording or reproducing device
Inventor: SHIOURA KUNIHIRO
IPC: G11B11/10
Filed: 1995-03-06
Abstract: PURPOSE: To shorten a read-in time by storing control information A of a new recording medium R, first reading in the control information B at a read-in operation of the control information and using the stored information A without reading in the information A when judging it as the same medium R. CONSTITUTION: When a TOC of a new disk 1 is read in, a system controller(SC) 11 reads in P-TOC information A by an optical head 3, and required information is stored in an S-RAM 11a. Then, the SC 11 reads in first U-TOC information B at the read-in operation of the control information, and refers to them by deciding the specified data in the information B, and decides whether or not the disk is the same as the last disk. When the same, the SC 11 uses the stored information A without reading in the information A, and when not the same, succeedingly, the SC 11 reads in the information A, and decides and processes whether the disk is a blank disk or a disk error. Thus, the read-in time is shortened using the stored information A, and a recordable/reproducible state is obtained in a short time.

Title: Laminate type electrophotographic sensitive body
Inventor: YAMASHITA MASATAKA
IPC: G03G5/043
Filed: 1984-04-09
Abstract: PURPOSE:To alleviate accumulation of residual potential due to traps, etc., at the time of repeated uses, to prevent deterioration of sensitivity and resolution, and to eliminate background staining by incorporating an esterified disazo pigment in the electrostatic charge generating layer of a laminate type photosensitive body. CONSTITUTION:The charge generating layer of a laminate type photosensitive body formed on a conductive substrate contains the esterified disazo pigment. Such as esterified disazo pigment is mixed together with an unesterified disazo pigment, and an insulating resin, such as PVK, in an org. solvent to form a coating fluid, and the charge generating layer is formed by coating the substrate with the fluid thus obtained. It is preferable to arrange a charge transfer layer on this layer. Since this esterified disazo pigment is good in dispersibility into a charge transfer layer, the use of such a pigment alleviates accumulation of residual charge at the time of repeated uses, so suppresses generation of traps in the charge generating layer, and prevents deterioration of sensitivity and resolution, and background staining of an image.

Title: Phase locked circuit

IPC: H03L7/12
Filed: 1983-04-26
Abstract: PURPOSE:To prevent the variation of the operating point because of temperature change and vibration or the like by providing a dead band to a charge pump circuit. CONSTITUTION:An output signal frequency f0 of a voltage controlled oscillator 2 and a frequency fR from a reference signal generator 5 are mixed by a mixer 4, and a reference frequency fS is fed to a phase detector 1 and a frequency discriminating circuit 7. The phase detector 1 compares a frequency fi with the reference frequency fS and transmits a DC error voltage corresponding to the phase difference to an analog adder 8. The discriminating circuit 7 gives a signal to a charge pump circuit 6 when the absolute value ¦fi-fS¦ being a difference between the frequency fi and the reference frequency fS is larger than a predetermined value DELTAf, and the circuit 6 increases a control voltage transmitted to the adder 8 by one step's share. Then, even if the input signal frequency fi is parted largely from the reference frequency fS, the circuit 6 traces the frequency fi so as to drive the phase locked loop into the capture range. Moreover, since the dead band DELTAf exists, the operating point is not fluctuated even with temperature change and vibration or the like.
