Abstract: PURPOSE:To convey settling solid particles smoothly from the inside of liquid onto a liquid surface by providing a stagnating section in the part right under the liquid surface between a scraping section and a dehydrating section. CONSTITUTION:A stagnating section 6 is provided in the part right under a liquid surface 3 between a scraping section 4 and a dehydrating section 5.

Title: Alignment method
Inventor: HIRUKAWA SHIGERU
IPC: H01L21/30
Filed: 1993-06-14
Abstract: PURPOSE:To perform alignment with high throughput and accuracy even if a sample shot has a nonlinear array error. CONSTITUTION:The coordinate value in a stage coordinate system (X, Y) is measured and then array coordinates in terms of calculation of each sample shot in the EGA system are obtained from the measurement result for sample shots SA1SA19 selected from a wafer W. The coordinate values in the stage coordinate system of adjacent substitution shots SB1. SB7, and SB15 are calculated for specifical sample shots SA1, SA7, and SA15 where the amount of nonlinear error obtained by subtracting the array coordinates in terms of calculation from the measurement result is large. By comparing the specifical sample shots with the amount of nonlinear error of the substitution shot, a shot used for calculating coordinates is determined.

Title: Video signal processing circuit
Inventor: FUKUOKA TOSHIMI
IPC: H04N5/92
Filed: 1988-06-08
Abstract: PURPOSE:To improve an S/N by executing emphasis processing to respectively adding a preshoot waveform to the start edges and the end edges of the rising waveform part and the falling waveform part of an input video signal. CONSTITUTION:After the time base of a first high frequency emphasizing signal SP1 outputted from a first preemphasis circuit 3 is inverted in a time base inverting circuit part 5, a high frequency component is emphasized in a second preemphasis circuit 6. Therefore, a rising preshoot waveform and a falling preshoot waveform can be formed so that the waveforms can be divided for both sides of the start edge and the end edge of the rising waveform part. Consequently, the increase of the value between the maximum peak value and the minimum peak value of a high frequency emphasizing signal SP2 is suppressed by the emphasis processing by the second preemphasis circuit 6, and the enlargement of a dynamic range necessary for a processing circuit is prevented. Thus, the S/N can be improved.

IPC: B41M5/34
Filed: 1990-05-31
Abstract: PURPOSE:To obtain excellent color separability and coating aptitude by providing an intermediate layer based on gelatin or a gelatin derivative between a plurality of thermal recording layers. CONSTITUTION:Gelatin or a gelatin derivative is used as the material of the intermediate layer of a thermal recording material wherein thermal color forming layers are laminated in a multilayer form. Since a high concn. gelatin solution has good coating aptitude when it is held to proper temp. (30 deg.C or higher), when gelatin is applied as the main binder of the respective thermal recording layers and subsequently cooled by cooling air, the coating layer is gelled and dried in this gelled state to obtain a coated article having layered constitution generating no mixing of the respective layers. In this case, the wt. ratio of gelatin in the binder (water-soluble polymer) is set to 50% or more, pref., 65% or more. When a thermal recording layer contains an electron donating dye precursor and an acidic substance as thermal color forming components, either one of both components is melted by heating and both of them are reacted to form a color.

Title: Electrostatic charging device
Inventor: HIRUKO OSAMU
IPC: G03G15/02
Filed: 1985-06-28
Abstract: PURPOSE:To charge the surface of a photosensitive body electrostatically to a specific potential by providing a grid voltage control means which stabilizes the potential of a grid electrode and interposing a temperature dependent resistance element between the grid electrode and grid electrode voltage control means. CONSTITUTION:An electrostatic charging device C has a thermistor 12 interposed between the grid electrode 11 and a varistor 13. While recording operation is stopped, the electrostatic charging device C does not operates and no current passes through the thermistor 12 from the grid electrode 11. Consequently, the thermistor 12 generates no heat by itself and its resistance value is relatively high, so that the potential V9 of the grid electrode 11 rises in the beginning of the restart of the recording operation. Then, when a current flowing through the thermistor 12 is generated as the recording operation is carried on continuously, the thermistor 12 generates heat by itself and its resistance value decreases gradually, so that the potential V9 of the grid electrode 11 is stabilized at a potential determined by the varister 13. Consequently, the surface potential of the photosensitive body is held invariably constant.

Title: Phase correcting device and recording medium
Inventor: IWATA KAZUMI
IPC: G11B20/10
Filed: 1993-05-21
Abstract: PURPOSE:To obtain data of exact length at the time of reproduction even when an inter symbol interference exists by varying adaptively a phase correction quantity of data in accordance with a data list of recording data. CONSTITUTION:A phase of a rise and a fall of recording data WD is corrected by allowing it to lead or lag as indicated with WH of a full line. The correction quantity DELTAtaun in this case is determined in accordance with a data list, since a degree of an inter symbol interference is varied in accordance with the data list. For instance, the correction quantity DELTAtau4 of a rise edge E1 is determined by data length of WD1 and WD2 being the data before and behind it. When a reproducing waveform RW of a recording pit pattern WP corresponding to the correction data WH is binarized, based on a threshold level SL, reproducing data RD is obtained. This reproducing data RD coincides with the original recording data WD.

Title: Protective circuit for amplifier

IPC: H03F1/42
Filed: 1979-11-05
Abstract: PURPOSE:To make broad the range where an amplifier can normally be operated, by shifting the protective line determining the start of protective operation according to the frequencies. CONSTITUTION:A frequency response circuit B produces smaller output as the frequency component included in the output signal is higher. This output signal is detected and when it exceeds a given threshold value with a Schmitt circuit, it becomes a signal in ''H'' level and input to the logical sum E. That is, no ''H'' appears at the output, if the output amplitude is greater as the frequency is greater. A short-circuit detection circuit C outputs the signal of ''H'' level if the load has a short-circuit. The limit circuit G to the amplifier A can be operated, when the output of the frequency response circuit B is at ''H'' or the output of the short-circuit detection circuit C is at ''H'', and when the output of the ASO detection circuit D is at ''H''.
