Title: Optimizing method of read channel of data recording device utilizing discoid recording carrier
Inventor: GO KOUBIN
IPC: G11B5/09
Filed: 1995-04-10
Abstract: PURPOSE: To optimize the read channel of a data recorder, making its reading characteristic variable easily in response to the characteristic of the data recorder, by altering the bandwidth of a low-pass filter to make the bandwidth of the signal read from a disk adjustable. CONSTITUTION: First, to a low-pass filter and equalizer 50 of the read channel of a data recorder, the default values of their bandwidth and boost level are set. Then, performing the writings/readings of data in/from the data recorder under its worst condition, the error occurrence rate of the read channel is computed and compared with a reference error rate to judge the default values as their optimization values when the error occurrence rate is low. When it is high, altering the boost level of the equalizer 50, the error generation rate is computed to determine the boost level corresponding to the lowest error occurrence rate in that time. Then, comparing again this lowest error occurrence rate with the reference error rate, that boost level is judged as the optimization value when the error occurrence rate is low.  When it is high, altering the bandwidth of the low-pass filter 50, the error occurrence rate is computed to determine the bandwidth corresponding to the lowest error occurrence rate in that time. Then, comparing again this error occurrence rate with the reference error rate to judge that bandwidth as the optimization value when the error occurrence rate is low.

Filed: 1989-04-03
Abstract: PURPOSE:To perform zero-point adjustment and temperature with high accuracy by forming a resistor for the zero-point adjustment of a bridge circuit composed of strain gauges in the same process with the strain gauges. CONSTITUTION:Respective resistors R1 - R4 are diffusion layers formed on the same substrate as a semiconductor substrate where the strain gauges RA - RD constituting the bridge circuit are formed and the line width of the diffusion layers is equal to the width of the strain gauges RA - RD. The strain gauges RA - RD which constitute the bridge circuit and the respective resistors R1 - R4 of a zero-point adjusting circuit are formed in the same process at the same time and resistance values of the strain gauges RA - RD and the temperature coefficients of the resistors R1 - R4 to the resistance values are nearly equal. Consequently, the resistors R1 and R2 which can be trimmed are only trimmed to adjust the zero point of the bridge circuit, thereby performing high-accuracy temperature compensation and zero-point adjustment.

Title: Detecting device for thickness of clinker layer
Inventor: KATOU KAZUO
IPC: G01B7/06
Filed: 1980-06-25
Abstract: PURPOSE:To secure a constant monitor for the height of a clinker layer to control the height of layer, by hanging rotatably a swing damper into the shift space of a clinker and providing a device that detects and indicates the angle of rotation of the swing damper to the shaft of the swing damper. CONSTITUTION:A bearing 13 is attached to the side wall of a waste heat collecting device main body 3, and both a shaft 12 supported by the bearing 13 and a swing damper 11 connected to the shaft 12 are set to freely rotate. An angle detector 14 is attached to an end of the shaft 12 to detect a rotational angle alpha in the form of a change of resistance value. This change is displayed by an angle indicator 15. If the relay thickness of a clinker 8 increases gradually from a proper value h1, the lower end of the damper 11 touches the clinker 8 and then has rotary movement toward the shift direction X by the flow of the clinker 8. In this case, the rotary angle alpha of the damper 11 is always monitored by the indicator 15. When the layer thickness reaches the danger value h2, the angle of that moment is detected to discharge the clinker 8.

IPC: H04N1/419
Filed: 1979-07-04
Abstract: PURPOSE:To make it possible to transmit facsimile signals without lowering a coding rate by using a buffer memory for line-synchronizing signals. CONSTITUTION:A picture signal for one line is converted by picture-signal coding circuit 1 into a signal of modified Hoffman codes or the like, which is sent to the 1st buffer memory. One-line end detecting circuit 4 counts the number of bits sent out of circuit 1 and sends a zero signal to the 2nd buffer memory 5 until the count value reaches the number of bits for one line; and then write control circuit 2 is driven while a signal of ''1'' reaching the number of bits for one line is sent to memory 5 and circuit 2 stops circuit 1 and memory 3 and 5 from operating. Signal transmission from memory 3 to gate circuit 7 is carried on from when the output of memory 5 changes from ''0'' to ''1'' until it further changes to ''0''. Then, the change from ''1'' to ''0'' is detected by line-synchronizing signal generating circuit 8 and after the detection, signals of ''1'' are sent to circuit 7 to obtain line-synchronizing signals.

IPC: B41J2/205
Filed: 1985-04-22
Abstract: PURPOSE:To enable shading of any choice to be varied in multicolor printing with improved reliability and lowered cost by providing plural heating elements and plural ink discharging nozzles. CONSTITUTION:A nozzle section 10 is provided below a ceramic substrate 6 with plural heating elements. If a recording medium 12 is sent by a paper feeding means to a position where said medium 12 is opposed to the nozzle section 10, a carriage begins moving by a carriage movement means. An electric signal signal is input to a piezoelectric transducer 11 by a control circuit, and the piezoelectric transducer 11 repeats a cycle of contraction and relaxation in response to the electric signal. Consequently, ink droplets are sent flying from the tip of the nozzle section 10 to form characters or images on the recording medium 12. The formed characters or images are transmitted to a position opposed to the ceramic substrate 6 by the paper feeding means. Then a required electric signal is input to the heating element 7, synchronized with movement of the carriage 3 in a digital direction by the control circuit. This results in the heating of only portions of the already formed characters or images requiring shading variation, thus generating the variation.
