Title: Image forming device
Inventor: NARA HIROSHI
IPC: G03G21/00
Filed: 1993-12-29
Abstract: PURPOSE:To provide an image forming device capable of forming an image well without having black noise even though an original is a book. CONSTITUTION:A book mode is set in the case of turning on a book mode key. Areas corresponding to the leading edge of the original, the central part of the original, and the trailing edge of the original in a reading direction among the areas of the image read from the original D, for example, book, are eliminated from the areas on which image forming processing is performed. The width of the eliminated area is set in accordance with the output of an original thickness detecting means. When the original D is book, the leading edge of the original, the central part of the original and the trailing edge of the original can not sufficiently reflects light from an exposure lamp so as to cause the black noise on a copying paper P. Image formation on the noise area is inhibited, so that the good copy can be obtained.

Title: Gyro sensor
Inventor: YAMAMOTO HIROSHI
IPC: G01C19/5719
Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To obtain a small-sized inexpensive gyro sensor by detecting the moving state of a weight section which moves along a circular orbit in a plane, when the weight section moves to the outside of the plane. SOLUTION: When an angular velocity ω1 is applied to an oblique shaft, a vertical force is applied to a weight section 11 revolving in a plane because a Coriolis force acts on the weight section 11, and the weight section 11 is apt to continuously revolve in the plane along an orbit ascending to the right or descending to the left. In this case, electrodes 12-15 are set in such a positional relation that the electrodes 12-15 cannot exceed the electrode range of each base electrode. For example, when the interval between electrodes is checked, the interval between the electrode 12 and its base electrode increases and the interval between the electrode 14 and its base electrode decreases. The interval of each electrode plays the role of a capacitor and, when the interval changes, the capacitance of the capacitor changes.  A voltage is applied across the electrodes and the electric current flowing to each resistor changes. When the terminal voltage of each resistor is measured, the degree of the angular velocity added to the weight section 11 revolving in the plane can be detected.

Title: Printing device and method for controlling the same
Inventor: KAKIGI MUTSUAKI
IPC: B41J5/30
Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of the repetition of a buffer full error resulted from the transmission of a buffer full message. SOLUTION: Increasing data amounts to a transmission buffer in a prescribed time are counted as a counter A, and decreasing data amounts are counted in the same way as a counter B. The increasing and decreasing speed M of data is calculated from the value (S602), and when the data amounts are larger than a threshold value, and the increasing and decreasing speed indicates increase twice in a row (S603-S605-YES), it is judged that the transmission buffer is full, and the result message is outputted (S606). Otherwise, it is judged that the transmission buffer is not full, and an already outputted full message is taken out (S610). Afterwards, the counters A and B are reset, and the measurement is repeated. Thus, the useless buffer full message can not be outputted by checking the increase tendency of the data amounts without simply checking the buffer full state.
