Filed: 1985-09-30
Abstract: PURPOSE:To remove an interference between a signal having specified frequency and a signal having switching frequency by controlling stabilization on the basis of the signal having switching frequency synchronizing with the signal having specified frequency in a digital processing circuit. CONSTITUTION:When using a PCM processor, switching transistors TR2, TR3 are switched, synchronizing with a clock 2WCLK for holding a sample, thus removing the deterioration of the SN ratio of a voice band by an interference between the switching frequency of the switching transistors and the frequency of the sampling clock 2WCLK. When the PCM processor is not employed, the switching transistors TR2, TR3 are controlled on the basis of the free- running oscillation of a switching frequency oscillating circuit 1, thus supplying a VTR section with stable voltage regardless of the usage of the PCM processor.

Title: Method for correcting track servo offset of optical disk device
Inventor: MINAMI AKIRA
IPC: G11B21/10
Filed: 1989-08-23
Abstract: PURPOSE:To remove also the offset of a track error signal by detecting the amplitude values of the positive and negative sides of a track error signal outputted from a track control part and correcting the offset in accordance with the difference between both the amplitude values. CONSTITUTION:A track error signal TES is outputted from a TES forming circuit 30 and a zero-crossing detector 34 detects the positive and negative side amplitude values of the signal TES and computes the difference of both the amplitude values. An amplitude difference detector 7a inputs the signal TES and detects the peak holding levels of the positive and negative sides and an offset value is outputted from an inversed amplifier 37 of the peak difference detection circuit as a peak difference. A main control part MPU 5 changes the value of a DAC7C in accordance with the peak difference, finds out an offset correction value and also corrects a signal TESd. Consequently, offset based upon the signal TES can be removed in addition to the removal of a circuit offset and an error rate due to the drop of cross-talking between trucks can be improved.

First an ion beam is made incident on a surface of the lower magnetic pole 8 at a 50 deg.-90 deg. angle, thereby, trimming on the surface of the lower magnetic pole 8 is carried out efficiently and reduction of a pole length is suppressed. Then the trimming of an upper magnetic pole, strictly speaking trimming treatment to a side surface of a pole 16a is carried out. A tilt angle of a wafer is set to 50 deg.-80 deg. and the ion beam is made incident on the side surface of the pole 16a at the angle near to perpendicular to the side surface. Thus, the trimming of the pole 16a can be carried out efficiently.

IPC: A47K3/00
Filed: 1995-08-25
Abstract: PROBLEM TO BE SOLVED: To provide a circulation hot bath unit of safety and high reliability by providing the bath unit with a check valve to discharge water from a main body container, and shield intrusion of water from the outside of the main body container on a bottom surface of the main body container in which a heater, a control device, and a power supply part are contained.

A DC voltage for control is supplied from the power supply part 31 through a connector to a control device in a control device box 9. Dew condensation water generated in a main body container 2 is discharged from a check valve 11, and in the case where bathwater overflows onto a bathroom floor 37, a valve element of the check valve 11 closes a valve seat by its floating force for preventing intrusion of water from the external into the main body container 2. Inner water can thus be surely discharged in such a very simple constitution as this, and external water can be shielded.

Filed: 1984-10-18
Abstract: PURPOSE:To answer a call from a trunk line only by picking up a handset by registering beforehand an extension to answer a dispersion trunk line incoming call with priority as a dispersion answer service class extension and connecting immediately a dispersion answer to a dispersion answer service class extension related to the calling. CONSTITUTION:When the extension is hooked off and the calling is detected, a central processing device CC decides whether or not the extension is a dispersion answer service class extension EXT.A. At a main memory device MM, it is registered beforehand which extension is a dispersion answer service class, and when this is compared and collated with calling information, the service class of the hooked-off extension can be known. When the hooked-off extension is a dispersion answer service class extension, it is detected whether or not a trunk line during the incoming exists at a trunk line trunk COT for dispersion incoming in correspondence to a dispersion extension group related to the calling, since it is the calling from the extension. As the result of the detection, the trunk line during the incoming exists, and then, the section between the trunk line and the calling subscriber EXT.A is connected with a channel 2.

Title: Belt-type transfer member and image forming device
Inventor: NAKAZAWA AKIHIKO
IPC: G03G15/16
Filed: 1999-07-30
Abstract: PROBLEM TO BE SOLVED: To stably rotate a belt-type transfer member and to obtain color image with little color slurring due to its meandering by importing difference between the right and left on the diameter of the belt of the belt type transfer member so that sidling force may be generated. SOLUTION: If the peripheral length of both ends of a belt-type transfer member is defined as LA and LB, LA and LB and the peripheral length LX of an optional point between LA and LB are always in the range where LA>LB and LA>=LX>=LB(here, excluding LA=LX=LB), and a difference between the average value and the maximum value or the minimum value of the peripheral length is 1.6 to 10 mm. When the difference between the average value and the maximum value or the minimum value of the peripheral length of the belt is smaller than 1.6 mm, appropriate transverse stress is not generated, so that meandering is cannot be regulated. However, if the difference in the peripheral length is larger than 10 mm, the stress in the lateral direction generated when the belt is rotated is too strong such that is disturbs stable traveling or causes the belt to break.  Therefore, it is necessary that the difference between the average value and the maximum value or the minimum value of the peripheral length of the belt be set between 1.6 to 10 mm.

Title: Discarded toner recovering device
Inventor: KOBAYASHI TAKESHI
IPC: G03G21/10
Filed: 1988-08-31
Abstract: PURPOSE:To prevent damage of a driving system such as a driving motor by employing a coupling member which stops the rotation of carrying members when load torque is increased. CONSTITUTION:A discarded toner recovering device is provided with the coupling member 20 so that it cuts off transmission when load torque is increased between the carrying members 15 and 17 and rotation drive transmitting shaft 22. When the amount of recovered toner reaches a certain value, the rotational loads of the carrying members 15 and 17 are increased. In this condition, the coupling member 20 does not transmit the rotation of the driving shaft 22 to the carrying members 15 and 17, thereby stopping the rotations of the carrying members 15 and 17. A motor and others are not subjected to the rotational load of the carrying members 15 and 17. Since overload is eliminated, a driving motor and others are prevented from being damaged.
