Patent JP-S6166588-A (JP)
Title: Motor drive circuit
Inventor: KANNA MUNETAKE
IPC: H02P7/29
Filed: 1984-09-05
Abstract: PURPOSE:To suppress a spike voltage or a noise to small values by providing a switching circuit for switching the time constant of a gate voltage drive circuit. CONSTITUTION:When a drive signal Si2 becomes L level, a transistor 6 is turned ON, a gate voltage drops in response to the time constant determined by the storage capacitor of a P-channel power MOS transistor 7 and a resistor 5, and the transistor 7 is turned OFF. When the signal Si2 then becomes H level, the transistor 6 is turned OFF, the gate voltage of the transistor 7 slowly rises in response to the time constant determined by the storage capacitor and the resistor 4, and is turned OFF. Thus, the gate voltage is controlled by a large time constant by the ON and OFF of the transistor 7 to suppress the spike voltage, then switched to a small time constant to prevent a longitudinal current due to the erroneous operation of the gate voltage.

Title: Controller for hot water temperature at exist of air-cooled type steam condenser
Inventor: MORI TAKASHI
IPC: G05D23/00
Filed: 1987-07-27
Abstract: PURPOSE:To improve the stability of exit hot water temperature control, by attaching a function which controls a condensate position so as to be always set at a constant level from values obtained by measuring a temperature in a condenser in a direction of the flow of steam at several points by using a deviation decision function.

Title: Heat-sensitive recording sheet
Inventor: INAGAKI SEIJI
IPC: C07F9/12
Filed: 1988-07-27
Abstract: PURPOSE:To obtain a heat-sensitive recording sheet with exceedingly high coloring sensitivity and also excellent stability of a color development section and a non-color development section by using nuclear halogen-substitution aromatic ester phosphate and/or nuclear halogen-substitution aromatic ester phosphite. CONSTITUTION:Nuclear halogen-substitution aromatic ester phosphate and/or nuclear halogen-substitution aromatic ester sulphite with a melting point of 65 deg.C or more can be used as a coloration improver. Especially those with a melting point of 65-120 deg.C having superior stability at normal temperature and coloration sensitivity during heating are favorable. The reasons are as follows: The hydrolysis by acidic materials such as bisphenol A is accelerated due to the electron absorption by halogen atoms during thermal melting, and the rings of color-developing lactone compounds are easily opened with resultant concentrated phosphorous acid. Consequently, coloration sensitivity is increased and thermal resistance at temperature lower than the melting temperature is increased by the barrier effects of halogen atoms thus contributing to color stability.
