Title: Plant raising vessel
Inventor: GO JOICHI
IPC: A01G9/02
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To provide a vessel by which a plant can sufficiently absorb a fertilizer by using reed pulp as a main raw material. SOLUTION: A reed cut into suitable size, for example, is heated in steam at 25 deg.C for 2.5 hours under high pressure so that the reed pulp can be extracted. Next, with the reed pulp of 99wt.% and water permeabile additive agent of 1wt.%, a plant raising vessel A with thickness of 1mm, diameter of the base of 60mm, diameter of opening on the upper surface of 80mm and height of 80mm is produced. Soil 6 and fertilizer 8 are put into the plant raising vessel A while being mixed in the ratio of 1:1, the seedling of plant 5 is transplanted and, in such a state, the vessel is buried in a hole 10 dug for the depth of 100mm under a surface 9 of the ground so that the plant can sufficiently absorb the fertilizer while preventing the fertilizer from being dissolved and dispersed in the soil for a fixed period until the vessel is decomposed and eliminated.

Title: Developing method for photosensitive organic film
Inventor: TANAKA KOUKICHI
IPC: H01L21/027
Filed: 1987-03-31
Abstract: PURPOSE:To remove defective development by bringing a distance between a developer outlet and a photosensitive organic film to at least 5mm or less and uniformly flowing down a developer without taking in components in atmospheric air. CONSTITUTION:A distance (d) between a developer outlet 2 for a nozzle 1 and a photosensitive organic film 3 on a wafer 4 is brought to 5mm or less, and brought near as much as possible. Consequently, components in atmospheric air are not taken in until a developer is discharged from the outlet and reaches the photosensitive organic film, thus removing defective development due to bubbles. The deterioration of development capacity due to the neutralization reaction of CO2 in atmospheric air and the alkaline developer is also prevented.

Title: Piezoelectric oscillator
Inventor: KUDO TETSUO
IPC: H03B5/32
Filed: 1987-03-31
Abstract: PURPOSE:To decrease the fluctuation of an oscillated frequency due to a power voltage change by controlling the output frequency of a VCO in response to an output of D/A conversion for power voltage compensation. CONSTITUTION:An A/D converter 1 detects a power voltage change and its output code is stored in a memory 2. If the power voltage changes, a voltage address signal inputted to the memory 2 changes and a voltage compensation digital code is read from the memory 2 accordingly, subject to D/A conversion 3, and fed to the VCO 4 as a control voltage. Thus, a voltage compensation digital code in response to the F/V characteristic of the VCO 4 is prepared to compensate the fluctuation of the oscillation frequency in response to the fluctuation of the input power.

Title: Structure of motor
Inventor: SUZUKI YUZURU
IPC: H02K37/24
Filed: 1996-03-08
Abstract: PROBLEM TO BE SOLVED: To increase the durability of a motor even if it has a simple structure by forming either one of slidable contact sections with PPS resin and forming the other one with metal and then forming a nitride layer on the surface of the metal-made slidable contact section. SOLUTION: An output shaft 1 has a male screw section 2 which is made of stainless steel and a D cut section 3 for preventing rotation which is installed for preventing the output shaft 1 from rotating relatively with an actuator. The output shaft 1 also has a straight section 4 which makes a straight-line motion. On the surface of the output shaft 1, especially on the surface of the male screw section 2, a nitride layer is formed by nitriding for the purpose of decreasing a frictional resistance and increasing the durability. A rotor sleeve 6 is made of PPS resin and has, on its inner face, a female screw section 7 to fit in with the male screw section of the output shaft 1 and has rotor magnets which are permanent magnets adhered on its outer face.  By using a combination of this output shaft 1 and the rotor sleeve 6 at a contact face, the wear of, especially, the PPS resin section is made small and an aging change in that section is also made small. Therefore, a positional accuracy of the output shaft 1 can be kept higher than by combentional methods even if the output shaft 1 is kept in contact with the rotor sleeve for a long time.

Abstract: PURPOSE:To realize the accurate reading scan by comparing the output of a photoelectric converting element with a reference level via a comparator before an original reading job is started, and confirming that the prescribed output is obtained. CONSTITUTION:The tube wall temperature of a fluorescent lamp 2 is detected by a temperature detecting element 6 and the energization of a heating element 7 is controlled so that the lamp 2 is kept at a prescribed temperature.
