Title: Semiconductor laser output control equipment
Inventor: TAKEYAMA YOSHINOBU
IPC: G03G15/04
Filed: 1986-09-30
Abstract: PURPOSE:To make it possible to control stably a semiconductor laser without deteriorating characteristics, by providing a protection circuit which prohibits a timing signal when the output signal of a photo-detector is less than or equal to a specified value, and an initial value set circuit which sets sample mode after a specified time when the reset signal of a circuit system is generated. CONSTITUTION:A photo-diode 2 generates a current proportional to the light output of a semiconductor laser 1, and an error amplifier 4 amplifies the error against a reference voltage Vref. This value is subjected to sample-hold by a timing signal. The driving current of the semicondnctor laser 1 is stabilized as a value corresponding with the reference voltage Vref and the light output of the semiconductor laser 1 is controlled so as to be constant. Further the semiconductor laser 1 is subjected to on/off operation by a modulation signal. When the semiconductor laser 1 is not in the burning state, sampling is prohibited, and an excess current does not flow through the semiconductor laser 1, so that the deterioration of the semiconductor laser 1 can be prevented. The initial value set circuit 10 generates timing signal after a specified time when the reset signal of a circuit system is generated, and sets a sample hold circuit 5 in a state of sample mode through an OR circuit.

Abstract: PROBLEM TO BE SOLVED: To enable the supply of an environment or nutrients such as fertilizers in the optimal state in a raising process for plants by analyzing a response information signal (a plant language) of the plants for an external stimulus and applying the information signal. SOLUTION: Detecting sensors are initially stuck to a leaf or a branch of a plant and an external stimulus (heat, magnetism, electricity, an external force, etc.) is positively applied to the plant. A change in biopotential flowing through the leaf or branch of the plant is then measured at this time. The waveform of the frequency of the measured electrical signal is subsequently analyzed to use the waveform as a reference one. On the other hand, the same external stimulus is then applied to a plant of the same species to be raised in the growth process to measure the change in potential. At this time, water or a fertilizer is respectively fed to the plant or conditions for irradiating with light from a lamp are adjusted when the waveform is not produced or hardly produced or the measured waveform is changed as compared with the reference one.

Title: Monitoring system of omission of card
Inventor: NAKANO YOSHIAKI
IPC: H04Q11/04
Filed: 1982-12-30
Abstract: PURPOSE:To monitor the omission of a card without increasing the scale of a scanner by providing a control circuit which stores temporarily the information showing whether the card to be inserted to a shelf is omitted or not. CONSTITUTION:A multiplexer MPX2 of a shelf common circuit SHC produces a PCM signal and transmits it to a highway IHW. Then the PCM signal is supplied to a time division exchange TD together with the signal supplied from a digital terminal DT having the same constitution as the IHW. While the SHC stores temporarily the information showing whether or not the card to be inserted to the shelf is omitted. A control circuit CNT selects a selection signal line SEL, and a signal is sent to a gate G0 of a card C0 for example. Then the gate G0 opens and some signal is sent back through a common line B. If the card C0 is omitted, the connection is broken at a connection part CON. Thus no signal is sent back although the selection signal is sent to the gate G0.
