Title: Mat and mat shrinkage control process
Inventor: TSUKAMOTO KOSHI
IPC: B29D99/00
Filed: 1992-01-31
Abstract: PURPOSE:To control the shrinkage of a single piece formed mat of thermoplastic resin when its softening temperature is almost reached. CONSTITUTION:The lawn part 12 of the subject mat is apt to shrink comparatively easily, if a temperature increases to almost reach the softening point of the mat, while the edge part 14 does rather hardly shrink. These parts are connected together at an L connection line. An external periphery projecting strip part 30a is provided slightly inside a side which is not connected to the edge part 14 at the lower side of the lawn part 12. Further, a diagonal projecting strip part 30b is provided inside the periphery projecting strip part 30a. If a temperature reaches the softening point, the lawn part 12 is prevented from shrinking in the direction of the periphery projecting strip part 30a and the diagonal projecting strip part 30b, so that the shrinkage is controlled across the entire area of the lawn part 12. Thus it is possible to prevent the edge part 14 from causing an undulating deformation.

Title: Millimeter wave fm-cw radar device
Inventor: ISHITOBI TOKUMASA
IPC: G01S13/34
Filed: 1998-02-13
Abstract: PROBLEM TO BE SOLVED: To reduce a nonlinear error by generating a quasi-chopping wave signal by a chopping wave signal generating means according to such conversion rules as to compensate the nonlinearity of a millimeter wave signal oscillator, and modulating the frequency of the millimeter wave signal oscillator. SOLUTION: An analog chopping wave signal is generated by an analog modulation signal generating part 20, and a millimeter wave signal oscillator 21 is modulated in frequency by the chopping wave signal to generate a millimeter wave signal. A transmitting antenna 22 sends out the millimeter wave signal, and an input signal of reflected wave from a target 23, received by a receiving antenna 24, is demodulated by a remodulator 25. Nonlinearity generally exists in the millimeter wave signal oscillator 21, but in this case, a nonlinear error is compensated by generating a chopping wave (quasichopping wave) signal following conversion rules predetermined to compensate the nonlinearity of the millimeter wave signal oscillator 21. The nonlinear error is not therefore generated even if expanding the modulation deviation of frequency modulation.

IPC: F16C13/00
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To prevent the leakage of toner from a developing unit by specifying the surface roughness of the side surface of a developing roller. SOLUTION: In the developing roller 211, its shaft 212 is rotatably supported by the sidewall of a case main body with bearing members. A gear for rotationally driving the developing roller 211 is fixed on one end of the shaft 212 and a transmission gear for transmitting power from a drive source is engaged with the above-mentioned gear. Further, rollers are rotatably provided on both ends of the shaft 212. These rollers come into contact with flanges provided on both ends of a photoreceptor, when the developing roller 211 comes into contact with the photoreceptor, to regulate the position of the developing roller 211 with respect to the photoreceptor. In such a case, the surface roughness Rmax of the side surface of the developing roller 211 is set <=0.5μm.  Thus, the toner is never carried with the rotation of the developing roller 211, because the toner is not held on the side surface of the roller 211.
