Title: Optical information recording medium
Inventor: HAMADA EMIKO
IPC: G11B7/246
Filed: 1986-06-07
Abstract: PURPOSE:To further reduce the incidence of bit error, by containing an org. compound having a decomposition point within a range from the m.p. of an org. dye to specific temp. in the org. dye of a recording layer. CONSTITUTION:An optical information recording medium has a recording layer containing an org. dye and constituted by containing an org. compound, which has a decomposition point within a range of the m.p. of said org. + or -10 deg.C, in the org. dye. The org. compound having the decomposition point near to the m.p. of the org. dye is added to said org. dye in order to enhance the thermal decomposition property of the recording layer due to the heat adsorption of semiconductive laser. The difference between the m.p. and the decomposition point is limited to the + or -10 deg.C range because the thermal decomposition property of the recording layer becomes abruptly low when said difference is equal to or more than said range and the generation rate of a bit error does not become quite different from a conventional one. The m.p. of the org. dye of the decomposition point of the org. compound often have a certain width. In this case, the min. or max. value of the decomposition point of the org. com pound to be added must be contained between the min. value of -10 deg.C of the m.p. of the org. dye and the max. value of +10 deg.C thereof.

Title: Ionization smoke detector
Inventor: FUJISAWA TAKAO
IPC: G08B17/10
Filed: 1979-10-16
Abstract: PURPOSE: To prevent malfunction owing to the smoke of cigarrettes etc. by providing a timer circuit which operates a switching circuit when inputted for more than a fixed time even if the detecting level of the smoke is low in an ionization smoke detector.  
     CONSTITUTION: In the case of the smoke of a cigarrette or the like, it may reach the density at which a high sensitivity level detecting circuit 4 operates, but hardly persists for a long time continuously. A timer circuit 5 resets immediately when there is no more output of the high sensitivity level detecting circuit 4, that is, when a transistor Q 3  is interrupted, because the charging charge of a capacitor C discharges by way of a diode D and a resistance R 7 . Because of this, even if the high sensitivity level detecting circuit 4 emits outputs plural times for a time shorter than the fixed time in the timer circuit 5, the detector will not operate.

Filed: 1989-05-26
Abstract: PURPOSE:To suppress the generation of shift shock by temporarily switching to low torque valve operating characteristic to start shifting when power-on and shift-up are conducted during operation with high torque valve operating characteristic. CONSTITUTION:When power-on and shift-up of an automatic transmission AT is conducted during operation of an engine E by using high torque valve characteristic by a variable timing lift mechanism, a control unit CU first switches the valve operating characteristic of intake and exhaust valves to low torque valve operating characteristic and, after delay of a determined time, operates the shift solenoids 251-253 of a hydraulic control valve CV to start the power-on and shift-up speed change. When the shift is completed, the valve operating characteristic is returned to high torque valve operating characteristic. Hence, the change quantity of the transmission output is reduced even if the changing rate at the time of shifting is unchanged, and the generation of shift shock can be suppressed by this extent.
