Title: Reproducing device
Inventor: AIDA AKIRA
IPC: G11B20/18
Filed: 1994-10-04
Abstract: PURPOSE: To enable fast response and stable automatic equalization by varying operation intervals in response to the state of an error in a regenerative signal while controlling the equalizing characteristics of an equalizing means. CONSTITUTION: Error-number information E is obtained by an ECC decoding circuit 6 from the input of a first reproducing equalizing circuit, and a CPU 10 controls the frequency characteristics of a reproducing equalizing circuit 9 by a control coefficient K on the basis of E. The ECC decoding circuit 6 generates an uncorrectable error flag EF at a synchronous block unit, in which a synchronizing signal is added to a plurality of image data blocks, at that time. The reproducing equalizing circuit 9 multipIies an input signal by a coefficient KA acquired by D/A converting the coefficient K, and controls transmission characteristics while using KA as a parameter. The CPU 10 controls the control coefficient K while monitoring error-number information E.  Accordingly, intervals when equalizing characteristics are controlled are changed in response to errors in regenerative signals, and equalizing characteristics can be controlled in optimum characteristics at timing corresponding to the states of the errors, thus conducting stable equalization.

Filed: 1999-08-26
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a silicon carbide semiconductor element of good characteristics by keeping the SiC surface clean and smooth after annealing for activating ion-implanted impurities. SOLUTION: A protective film is deposited before high temperature annealing on the surface where a mask and oxide film 3, etc., are removed after impurity ions 5 are implanted in the surface layer, so that a surface roughening is prevented while impurity atoms are suppressed form being desorbed from surface due to out-diffusion. A diamond-like carbon(DLC) film 4 or photo-resist is used for the protective film. After an organic film pattern such as photo-resist is formed, the film is carbonized to provide a graphite film which is used as a mask for selective doping by a thermal diffusion method.

Title: Image forming device
Inventor: OHIRA TADASHI
IPC: H04N1/387
Filed: 1986-10-09
Abstract: PURPOSE:To improve the operability of a picture forming device, by installing a control means which initializes editing coordinate values to values specifying the maximum editable area and input means which continuously bring up or down the initialized editing coordinate values to the picture forming device. CONSTITUTION:A control means 81 controls picture forming operations so that a picture can be or cannot be formed for the picture part corresponding to editing coordinate values only, and can edit formed pictures according to set coordinates. Since the control means 81 initializes editing coordinate values to values indicating the maximum editable area for picture edition, setting of the editing coordinate values can be made through a little operating work and desired edition can be attained quickly. On the other hand, when input means 61 and 62 which continuously bring up or down coordinate values are operated, the initialized coordinate values are continuously brought up or down so that the editable area can be made narrower and, when the operations of the input means 61 and 62 are canceled, the change in coordinate value is stopped. Therefore, if the operations of the input means 61 and 62 are canceled at the moment when the coordinate values are brought up or down to desired values, the coordinate values can be set to the desired values. Thus operability of this picture forming device can be improved.
