Title: Thermal recording apparatus
Inventor: TAKEU YASUHIRO
IPC: H04N1/23
Filed: 1983-11-11
Abstract: PURPOSE:To keep supply electric energy substantially constant and to make printing density constant, by controlling two high and low voltage power sources corresponding to the number of simultaneously driven heat generating elements. CONSTITUTION:At the time of operation, when image signals are transmitted to a shift register from an input terminal 13, the number of ''1'' signals in said image signals are counted by a counter 21 and blackening ratio is operated by a ratio operator 23 to supply the same to a function generator 23. A control pulse P2 corresponding to the blackening ratio is issued from the function generator 23 in response to the rising of the control pulse P1 and, at the beginning of the control pulses P1, P2, switching elements 18, 19 are brought to a continuity state and the driving of fhe switching element 19 due to a high voltage power source V(H) is performed. When the control pulse P2 is extincted, because the switching element 19 is blocked but the switching element 18 is still held under the continuity state, a heating current is supplied to the heat generating element selected corresponding to the image signal from a low voltage source V(L) through a diode. By this method, electric energy supplied to the heat generating element is kept almost constant even if the blackening ratio is changed.

Title: Wafer susceptor
Inventor: ITAYA HIDEJI
IPC: H01L21/205
Filed: 1997-08-06
Abstract: PROBLEM TO BE SOLVED: To reduce the amount of friction between a wafer and a wafer support point upon thermal distortion of the wafer, by providing a plurality of wafer support points in positions shifted from a lattice direction as a wafer deformation start point direction. SOLUTION: Four wafer support points 14 provided on a wafer susceptor 13 comprise support pieces projected in a diametrical direction of an opening 15 inwardly, and the wafer support points 14 are provided in positions shifted from a deformation start point direction of a wafer 1. For example, the support points 14 are provided in respective positions at 0 deg., 90 deg., 180 deg. and 270 deg., from an orientation flat or notch 2 formed in [100] direction of an Si wafer, as a start point. As a result, the support points 14 are shifted from the lattice direction of the wafer 1, i.e., [011] direction 7 or [011] direction 8. Accordingly, the support points do not correspond to the deformation startpoint direction of the wafer 1.  By this arrangement, upon elastic deformation of the wafer, the amount of friction of the wafer due to the wafer support points is reduced, thus occurrence of particles can be mitigated.

Abstract: PURPOSE:To avoid the deterioration of performance of a multi-processor by providing a buffer memory set corresponding to a main memory area where a high-speed access is received from a processor having high performance to a processor having low performance together with a buffer memory which is set corresponding to another main memory area. CONSTITUTION:A 1st processor 2 gives a high-speed access to a 1st area 11 to process data, while a 2nd processor 3 contains a 1st buffer memory 31 storing the copy of the area 11, a 2nd buffer memory 32 storing copies excepting the one of the area 11, and a 1st buffer memory invalidating circuit 36 which invalidates completely the memory 31.

Title: Video signal generating circuit
Inventor: ITO HIDETOSHI
IPC: G06F21/10
Filed: 1984-10-09
Abstract: PURPOSE:To obtain always without adjustment a pair of compound signals where the size (polarity) only is different with a level of a level indicating signal as a center by using a level indicating signal showing standards of a luminance level of the video signal included in the scrambled compound signal, and controlling to generate automatically a video signal level of the compound signal E of the same polarity and a video signal level of the inverted compound signal D to the same. CONSTITUTION:A differential amplifier 4 is constituted so that an illustration level indicating voltage in correspondence to a level indicating signal extracted out of the scrambled compound signal can be supplied as a reference voltage. Consequently, the video signal level in the compound signal E of the same polarity sent from a terminal E and a terminal D, and the video signal level in the inverted compound signal D are always preserved automatically to the same level. For this reason, when either of them is selectively changed over and the scrambled compound signal is generated, the compound signal having the high quality without a level fluctuation can be obtained.

Title: Digital information transmitter
Inventor: IDE AKIFUMI
IPC: H04B3/06
Filed: 1986-09-09
Abstract: PURPOSE:To automatically make the best adjustment by correcting the coefficient of an equalizer at every time while deciding whether error detection data generated by a reception-side processor increases or decreases. CONSTITUTION:The output of the equalizer 2 is applied to a detector 3, detected as a binary signal (ternary signal or more according to a modulation system), and demodulated by a demodulator 4. Error detection information generated by the processing stage of the reception-side processor 5 is led to a coefficient controller 8. The coefficient controller 8 controls the coefficient in the equalizer 2 in such a direction that an error frequency decreases according to an input error pointer. Consequently, the characteristics of the equalizer can be set automatically so that the error generation is invariably minimum, and even if a transmission line changes in state or when compatible reproduction is performed by a magnetic recording and reproducing device, the equalization characteristics need not be readjusted at every time.

IPC: G06K17/00
Filed: 1997-08-06
Abstract: PROBLEM TO BE SOLVED: To easily recognize that a record formed in an optical recording area from being optically altered in a case by discriminating whether or not the record is correct with a light passing through an optical recording area and light which is reflected. SOLUTION: An optical recording area 2 includes a wavelength selective reflecting body, which reflects a light in a specific wavelength band but passes a light of other bands and whether or not the optical record is correct is discriminated with the light transmitted through the optical recording area 2 and the reflected light. The wavelength selective reflecting body reflects the light (electromagnetic wave) in the specific wavelength band but transmits light of other bands. This wavelength selective reflecting body is, for example, a dielectric reflecting film. The dielectric reflecting film is constituted by stacking layers of light-transmitting dielectrics which are in contact with one another.  The relation between the thickness and refractive index of each layer is so determined as to have wavelength selective reflectivity, which is developed by a 1/4-wavelength multilayered film formed by stacking a 1/4-wavelength layer having a high refractive index and a 1/4-wavelength layer having a low refractive index alternately.
