Title: Multi-use ribbon rewinding system for printer
Inventor: WAKAMATSU NAGAKO
IPC: B41J33/14
Filed: 1988-11-16
Abstract: PURPOSE:To make it unnecessary for the user to carry out troublesome inversion of an ink ribbon by rewinding a fixed proportion of a previously obtained amount of the ink ribbon used for printing one line at the end of printing one line, thereby setting a starting position for the next printing. CONSTITUTION:An ink ribbon feed signal for one line is inputted from a printing-controlling part to an input terminal 1a, and is transmitted to a ribbon feed controlling part 1, where the amount of an ink ribbon to be used is obtained. The part 1 sends to a ribbon-feeding mechanism 2 a signal for feeding the ink ribbon for printing, and a multi-use ribbon 5 is fed according to the signal. Upon completion of printing one line, the part 1 sends a ribbon feed end indication signal to a ribbon rewinding controlling part 3. Simultaneously, the part 3 receives data on the amount of the ribbon used, from the ribbon feed controlling part 1, and determines an ink ribbon rewinding amount. The ink ribbon rewinding data thus obtained is sent to a ribbon-rewinding mechanism 4, whereby the multi-use ribbon 5 is rewound.

Title: Matrix type cathode-ray tube
Inventor: IWATSUJI ICHIRO
IPC: H01J31/15
Filed: 1985-12-24
Abstract: PURPOSE:To prevent a reflection of an incident light of the sun or the other lighting source at the surface of the glass, and avoid a difficult observation of the image owing to the reflection, by making a minute unevenness over the surface of the face glass. CONSTITUTION:A face glass 2A is processed mechanically to form a ground glass over the surface. Since the face glass 2A of the matrix type CRT is grinding-processed mechanically as if the surface is a frosted glass, the light of the sun or other lighting source is not reflected at the surface of the face glass 2A but scattered thoroughly, so that the plane reflecting light from the lighting source can be observed directly, resulting in a clearly observable image. Furthermore, the color mixture distances are made shorter.

Title: Molecular beam epitaxial system
Inventor: OISHI YOSHIRO
IPC: H01L21/26
Filed: 1986-12-05
Abstract: PURPOSE:To accurately control a composition without fluctuation in temperature due to no shutter being used by rotatably providing a substrate holder, and rotating the holder thereby to selectively irradiate a molecular beam from a specific deposition source crucible. CONSTITUTION:Since a molecular beam has good linear propagation, when the angle of a crucible and the angle of a substrate holder 2 are suitably selected, the conditions that Be is not irradiated to a substrate 3 to which an Si molecular beam is irradiated and Si is not radiated to the substrate 3 to which the Be molecular beam is irradiated can be satisfied. In this case, n-type and p-type grown films are formed on the substrate 3. Here, when the holder 2 is rotated, the Si molecular beam and the Be molecular beam are alternately irradiated to the substrate 3 to form a doping superlattice. In this case, when the rotating speed is controlled, a plurality of the superlattices of arbitrary thickness are formed simultaneously.

Abstract: PURPOSE:To always enable a focus search in a short time by providing a nonvolatile memory for storing an offset value of a focus driving signal, adding this offset value to a search signal and performing the focus search accordingly. CONSTITUTION:A D/A converter 41 and the nonvolatile memory 42 are provided, and the offset value of the focus driving signal is stored in the nonvolatile memory 42, and then this is set in a D/A converter 41 by a CPU 27 to be sup plied to an adder 22.

Then, the offset value is supplied as the offset value for the next focus search to the nonvolatile memory 42 to be stpred by updating the offset value. By this method, the updating can auto matically be performed in order to narrow the fous search range, and hence the focus search can always be carried out in a short time.

Filed: 1994-11-25
Abstract: PURPOSE: To currectly operate the focus servo control by closing a focus servo loop after bringing an objective lens near to the vicinity of a focusing point and changing over from a focus search signal to a focus error signal. CONSTITUTION: After the output signals of a quadripartite photodiode 1 are amplified by amplifier 11 to 14, a diagonal sum signal A is formed by inputting the output signals from diodes arranged diametrically (a pair of D1 and D2) to an adder 2a and (the diagonal sum signal A + a bias signal) is formed by adding the bias signal to the signal A by an adder 51. A diagonal sum signal B is formed by inputting the output signals from diodes arranged diametrically (a pair of D2 and D4) to an adder 2b. Both signals mentioned above are inputted to a comparator 52 to be compared and the comparator outputs a focusing point detection signal with the change of the state of its output signal.  The focusing point detection signal obtained in the comparator 52 is transmitted to a control part 7, which closes the focusing servo loop by judging that the objective lens is brought to the vicinity of the focusing point by the focusing point detection signal.
