Title: Method and device for recording magneto-optical medium capable of overwritting
Inventor: HOSOKAWA TETSUO
IPC: G11B11/10
Filed: 1992-02-07
Abstract: PURPOSE:To reduce reading errors by controlling the intensity of a laser beam through the use of a mark* spacing. CONSTITUTION:An original information is transformed into a cipher by a ciphering means 11 and the spacing between each signal defined by the end of a mark* and the beginning of the next mark is measured by a spacing measuring means 13. The measuring result and the compensation value of PL computed by a compensating means 14 are sent to a controlling section 16. A generating section 15 sets setting signals in accordance with the prescribed values of medium's laser beam intensity (high level PH low level PL). The section 16 controls the electric power from a power supply 10 to P4 and PL based on the setting signals. However, the value PL is decided based on the compensated value from the means 14. The PH and PL are inputted to a pulse modulation means 17, a laser beam driving waveform (Z) is formed by the PH and PL from the section 16 and the information signal (cipher) from an input section 12, inputted to a light source 18 which consists of a semiconductor laser and a modulated laser beam is outputted. Thus, the contour of the beginning and the end of a mark becomes clear, jitter of the reproduced signals are reduced and reading errors are also reduced.

Title: Flip-flop circuit
Inventor: SUZUKI YUUICHI
IPC: H03K3/2885
Filed: 1984-02-13
Abstract: PURPOSE:To decrease remarkably the effect of a spike noise by alpha rays from an IC package by setting a threshold voltage of a flip-flop circuit lower than a mediam of a logical amplitude. CONSTITUTION:Fig. shown the flip-flop circuit of series gate structure and a block L shown in broken lines indicates a threshold value setting circuit of the flip-flop circuit. An emiter output of a PNP transistor (TR) Q9 at a point P1 is fed to a base of a Q2 constituting an input side flip-flop gate as a threshold voltage and a collector output of a Q10 at a point P2 is fed to a base of a Q3 constituting a holding circuit flip-flop gate as other threshold voltage. Although the alpha rays emitted from the IC pakage give effect on the Q output holding a high level, since a base potential of the Q3 is set lower, the margin of the high level side surpasses the spike noise level due to the alpha rays thereby decreasing the effect of the alpha rays.

Title: Cooker
Inventor: ISHIKAWA HARUO
IPC: A47J27/00
Filed: 1990-01-31
Abstract: PURPOSE:To prevent this cooker from boiling over, and also, to miniaturize it by disposing a heater so as to heat the side being near the center of a heat radiation plate of a vapor hole and arranging a U-shaped part of the heater in the periphery of the vapor hole. CONSTITUTION:A heater 7 disposed on the upper face of the heat radiation plate 5 is provided so that a terminal part 8 becomes parallel, and a heater part 9 forms a U-shaped part 10, and the U-shaped part 10 is arranged so as to heat the heat radiation plate surface of the side being near the center of the heat radiation plate of a vapor hole 6. When water containing rice boils up, it becomes a sticky state and comes to bubble easily, and when it is further heated, the sticky hot water blows out of a vapor hole 3 of the inner cover 1. In this case, since the heat radiation plate surface of the side being near the center of the heat radiation plate of the vapor hole 6 is higher as to heating density than that of other heat radiation surface, a defoaming action in its part is strong, and bubbles overflowing to the outside of the outer cover 111 from the vapor hole 6 are defoamed. In such a manner, boiling-over does not occur, and the cooker can be miniaturized.
