Title: Watchdog timer
Inventor: NAGAE NORIYUKI
IPC: G06F11/30
Filed: 1986-12-11
Abstract: PURPOSE:To eliminate the malfunctions of a watchdog timer itself and at the same time to check the abnormality of an external clock, by utilizing an action counter of a CPU to detect the abnormality of the CPU. CONSTITUTION:When a negative pulse showing the normal working state of a CPU is applied via a differentiating circuit 2, counter 3 is cleared in an initial state and counts the external clocks supplied from an RC oscillator 1. Then a carry-over output is inverted to L from H and an output signal C which is changed to H from L by an inverter 4 and shows the normal state of the CPU is produced. If no negative pulse is inputted from the circuit 2 owing to the abnormality of the CPU, the counter 3 counts up to its maximum value. Then the carry-over output is produced and the signal C is set at L. In an omission mode of external clock a highest bit signal (d) outputted from the counter 3 is never inverted to H even after a normal time point of the CPU. This state continues for a prescribed period of time for decision of the abnormality of the oscillator 1. In such a constitution using no monostable multivibrator, a watchdog timer has no its own malfunction and also to abnormality of the external clock can be detected.

Title: Full color toner kit for electrophotography
Inventor: TAGAWA REIKO
IPC: G03G9/097
Filed: 1988-11-22
Abstract: PURPOSE:To obtain the full-color toner kit having excellent color reproducibility, color mixability and transparency by constituting the toner kit of colored toners consisting of a yellow toner, magenta toner and cyan toner and a colorless toner contg. a release material. CONSTITUTION:Original pictures are subjected to color sepn. and latent images are formed by each of the respective colors and are developed by the primary color and black toners corresponding to color sepn. filters; further, the images are developed over the entire surface of a transfer member by using the colorless toner contg. wax of a low m. p. as a release agent. Namely, the wax of the low m. p. incorporated into the colorless toner melts sufficiently at the fixing temp. or below and acts as a good heat transmittable material; therefore, the heat transmission at the time of fixing progresses efficiently down to the lower part of the multiple transfer images. As a result, the fixed images which are excellent in the color mixability and transparency are obtd. Further, the wax in this colorless toner acts as the release agent as well to prevent offset at the time of fixing. Paraffinic hydrocarbon having the m. p. ranging 55 to 70 deg. is used as the wax to be added into the colorless toner.

Title: Optical disk cutting device
Inventor: OSAWA SEIICHI
IPC: G11B7/09
Filed: 1989-11-10
Abstract: PURPOSE:To reduce the color aberration by decreasing a beam diameter of a focus servo laser made incident on the objective lens with a laser beam converging means and making the image forming position of an exposure laser beam the same regardless of the difference from a reflectance. CONSTITUTION:A focus servo laser beam from a laser oscillator 13 is made incident on a convex lens 21, where the beam is converted into a converging beam. Then the beam passes through a mirror 6 while being converged, is reflected in a reflection mirror 7 and made incident on an objective lens 8. Thus, the beam diameter for the focus servo laser is made smaller than the exposure laser beam diameter. Moreover, since the wavelength of the focus servo beam is longer than that of the exposure beam and the reflectance of the focus servo beam is smaller than that of the exposure beam, the image forming position by the lens 8 is made almost the same due to the reduced beam diameter and the color aberration is reduced.
