Title: Protective alarm structure for optical disk medium
Inventor: MACHIDA TAKASHI
IPC: G11B19/00
Filed: 1987-03-04
Abstract: PURPOSE:To prevent the reduction of the life of an optical disk medium and recording information due to accumulated heat in an internal device by giving alarm sound if a power source is in an off-state with the state that the optical disk medium is loaded. CONSTITUTION:If the optical disk medium 7 is inserted into the optical disk device, a load sensor operates to sense that the medium 7 is loaded and transmits signals to a decision controller 1. A detection circuit for power off state 3 checks whether a power circuit 8 operates or not and transmits the signals to the controller 1 if the power source is in the off-state. If the controller 1 receives both signals of the sensor 4 and the circuit 3, it transmits the signals to an alarm circuit 2. The circuit 2 gives alarm sound if it receives the signals from the controller 1. If power supply from the circuit 8 stops, a reverse current prevention diode 6 prevents a current from reversely flowing from a secondary battery.

Inventor: ARAKAWA ISAO
IPC: H01L21/339
Filed: 1978-04-27
Abstract: PURPOSE:To reduce the loss of the charge transfer at the barrier region by driving the charge transfer device in such way that the charge amount passing through the barrier region may be more than the charge amount to be transferred. CONSTITUTION:The relation of S1(phiSL-phibL)<=S2(phibH-phiSL) is prescribed for the charge amount to be stored at the storage region, that is, the relation between the charge amount to be transferred and the charge amount passing through the  barrier region at the charge transfer time. Here, S1 is the area of one storage region,  S2 is the area of one barrier region, phiSL and phibL are the storage region applied  with the L-level transfer voltage and the potential of the barrier region, and phibH is  the potential of the barrier region at the H level respectively. In such way, the  mixture mode of the surface channel and the buried channel does not exist, thus the transfer loss being reduced. Thus, the impurity density of each region has only to  be selected to 8 X 10<15> atom/cm<3> and 1 X 10<16> atom/cm<3> each when the region  ratio S1/S2 is set to 3.

Abstract: PURPOSE:To prevent generation of uneven density as against the contamination of a wire in controlling image forming conditions by controlling the intensity of the primary electrostatic charge current and the secondary electrostatic charge current by setting upper limit values for both and setting a lower limit value for either one thereof.

Title: Graphite mold for molding plastics
Inventor: TAKAGI TAKASHI
IPC: B29C45/26
Filed: 1990-03-01
Abstract: PURPOSE:To realize the graphite mold concerned, which has favorable workability and is handled easily and the strength of which is fully guaranteed, by a method wherein shock-absorbing member is interposed between base material and reinforcing member. CONSTITUTION:By interposing shock-absorbing member 14 between base materials 11 and reinforcing members 13, when force is applied from outside to a graphite mold for molding plastics 10, the force applied through the reinforcing members 13 to the base materials 11 is absorbed by the shock-absorbing member 14, resulting in applying almost no force to the base materials 11. Accordingly, no crack or no breakage develops in the base materials 11 by the force applied from outside. Further, molding pressure, which is developed by injected plastic material, is directly applied to a molding cavity surface 12, resulting in pushing the base materials 11 against the reinforcing member 13. At this time, the resultant force is absorbed by the shock-absorbing member 14 and consequently no crack and no breakage develops by said molding pressure.
