Title: Water supply cone
Inventor: OSHIMA REIJI
IPC: A01G27/00
Filed: 1994-09-30
Abstract: PURPOSE: To provide a water supply cone capable of simply performing the water supply to a plant for a long period. CONSTITUTION: This water supply cone 1 can readily be screwed into, e.g. soil 11 in a flowerpot 10 and simply installed therein due to its form of a hollow conical unit 2 gradually tapered toward the tip. Since the side part 2c in the interior of the hollow conical unit 2 is formed of a water-permeable member, water in the hollow conical unit 2 is permeated into the water-permeable member and further into the soil. Thereby, the soil is prevented from drying for a long period.

Title: Driving circuit for semiconductor laser
Inventor: MURATA KAZUHISA
IPC: H01S5/068
Filed: 1985-11-21
Abstract: PURPOSE:To form the titled driving circuit, which is superior in responsibility and also, is simpler in circuit configuration and at a lower cost by a method wherein, when the peak value of the photo output of the semiconductor laser fluctuates, the level of the DC bias current is made to change in such a way that the peak value becomes constant. CONSTITUTION:The luminous output of a semiconductor laser LD is received by a pin photo diode PD and is converted into a voltage by a variable resistor VR. The voltage between both ends of this variable resistor VR becomes a comparison voltage at a connecting part B. When this comparison voltage becomes larger compared to the reference voltage at a connecting part A, the output of an operational amplifier OPI is increased. Hereby, the base voltage of a transistor Q1 is boosted and a DC bias current Idc is decreased. With this, the driving current Id of the semiconductor laser LD including the DC bias current Idc is also decreased. When the driving current Id is decreased, the photo output Po of the semiconductor laser LD is reduced. Thus, the photo output Po of the laser LD is controlled to be constant.
