Title: Ignition control device for internal combustion engine
Inventor: IWATA TOSHIO
IPC: F02P11/02
Filed: 1986-01-30
Abstract: PURPOSE:To detect malfunction of an oscillator of an ignition control device with ease and prevent an engine from being interrupted, by determining that the oscillator is in malfunction when it does not output a clock signal and making ignition based on an ignition timing signal which is in synchronism with the rotation of the engine. CONSTITUTION:A ignition device 7 is supplied with an output signal from a control circuit 4 for energizing an ignition coil intermittently. ON the other hand, when a clock pulse is not output, the control circuit 4 interrupts to calculate an energizing timing and does not output an energizing timing signal. However, since a malfunction detection circuit 5 detects that the energizing timing signal is not output and a switching circuit 6 switches an output signal from the control circuit 4 to a waveform shaping circuit 2, the ignition device 7 continues to energize the ignition coil without interruption for thereby not interrupting an engine. In addition, the malfunction detection circuit 5 also outputs a signal to a display circuit 8 so that a drive is notified of the malfunction. Therefore, malfunction of an oscillator 3 can be detected with ease and the engine is prevented from being interrupted.

Title: Manufacture of acid soluble aluminum hydroxide
Inventor: SAKAMOTO AKIRA
IPC: C01F7/144
Filed: 1979-02-26
Abstract: PURPOSE: To cheaply manufacture aluminum hydroxide with enhanced solubility in acids by adding a small amt. of fine aluminum hydroxide as a seed to an alkali aluminate soln. contg. alumina dissolved in a supersaturation state.  
     CONSTITUTION: Aluminum hydroxide obtd. by the Bayer process is dry pulverized to fine powder of 3μ or less in average particle size on the basis of a sedimentation method. This powder is added as a seed to an alkali aluminate soln. contg. alumina dissolved in a supersaturation state in an amt. of 0.1W7wt% as alumina to the amt. of the dissolved alumina. The powder-added soln. is fed to a deposition process of the Bayer process, where aluminum hydroxide is deposited. The mechanism of forming this acid sol. aluminum hydroxide is estimated as follows: since the amt. of the seed added is small, alumina deposited is mainly consumed to form fresh aluminum hydroxide particles owing to uncleus formation, whereby slow growth of crystals does not occur, and the formed particles are rich in cohesion power.

Title: Detector for absolute measurement of radiation energy
Inventor: INABA HIROYA
IPC: G01J5/10
Filed: 1980-02-21
Abstract: PURPOSE:To perform an absolute measurement of radiation energy without using a standard light source by receiving a radiant rays from the window of a box to which a radiant ray absorbing membrane is fitted in order to change light to heat and installing a temperature detecting element and a heater for calibration inside the box. CONSTITUTION:Light to be measured is received from light receiving window 1 into box 2 made of a thin film. The received light is absorbed into black-painted absorbing membrane 3 inside box 2 and converted into heat. Since the internal temperature of box 2 rises in proportion to the quantity of incident light, the temperature is measured by temperature sensitive element 4 to measure the absolute value of incident light. In this case, accuracy will be increased by calibrating the increase of the loss of energy caused by the rise of internal temperature with heater 5 for calibration. Thus, absolute measurement is available for light with any kind of wave length without use of a standard light source by means of an extremely simple device.
