Title: Production of distributed index optical element
Inventor: NODA SATOSHI
IPC: C03C21/00
Filed: 1992-02-28
Abstract: PURPOSE:To easily produce the distributed index optical element having an excellent color diffusion characteristic. CONSTITUTION:The distributed index optical element having a concn. distribution in plural metallic components is produced by a sol-gel method. A second metal salt having the next smaller solubility is previously dissolved in a solvent to be exchanged at the time of imparting a concn. distribution to a first metal salt having the smallest solubility to gradually exchange the solvent in the gel with the solvent having the smaller solubility of the first metal salt and settling the metal salts in the form of fine crystals on the inside walls of the pores of the gel. The second metal salt dissolved in the solvent is diffused into the gel during the solvent exchange. On the other hand, the first metal salt has substantially no solubility with this solvent and, therefore, the precipitate is formed in the gel by the solvent exchange concn. distribution is fixed.

Filed: 1989-03-31
Abstract: PURPOSE:To improve working efficiency by employing such configuration that the number of counts of a pulse signal outputted corresponding to the amount of travel can be varied by stages. CONSTITUTION:The output of a counter circuit 7 is connected to the enable terminal 5a of each latch circuit 5, and the circuit 7 counts the number of pulse signals supplied from each frequency multiplication circuit 6 based on a driving signal from a switch circuit 8, and controls variably the number of counts of the pulse signal transmitted from the latch circuit to a computer. For example, when a signal of high level is outputted from the output 1 of the switch circuit 8, the counter circuit 7 is operated as a ternary counter, and the pulse signal with the number of counts of 1/3 the ordinary number is transmitted from the latch circuit 5 to a computer side. Therefore, it is possible to vary the number of counts of the pulse signal transmitted from a mouse 1 to the computer by several stages by the depressing operation of a switch 8a. In such a way, work can be efficiently performed.

IPC: F02D41/08
Filed: 1992-02-29
Abstract: PURPOSE:To prevent any engine stall from occurring by installing a control function which drives a drive motor and sets engine speed down to an objective idling speed in the case where an idle switch is turned off and the engine speed is lower than the objective idling speed. CONSTITUTION:When an internal combustion engine is started, a controlling program starts (100), thereby judging whether an idle switch is in a state of being turned of or not (102). When this judgment (102) is YES, a fact of whether engine speed NE is lower than the objective idling speed NE1 or not is judged (104). When this judgement (104) is YES, a fact of whether throttle opening THtheta is smaller than the throttle opening learning value TH1 or not is judged (106). When this judgment (106) is YES, a driving motor is operated to an extension side (108), the engine speed NE is raised up to the objective idling speed NE1. With this constitution, the driving motor can be operated to the extension side, thus an engine stall is prevented from occurring.
