Title: Charged particle energy analyzer
Inventor: KONO SHOZO
IPC: G01N23/225
Filed: 1990-03-23
Abstract: PURPOSE:To simultaneously measure the distribution of the emission angles of charged particles and to shorten measurement time by mounting an electrode for executing the deflection and speed change of charged particles to a slit of an incident port and providing a position sensitive type detector to the rear stage of an outlet aperture. CONSTITUTION:Only the charged particles having specific energy among the charged particles dispersed by an electrostatic concentrical spherical surface type energy analyzer 1 are converted through an exit slit 9 and an outlet aperture 10 to single energy. A deflecting electrode 11 maintains the same potential as the potential of the aperture 10 and can be impressed with an accelerating voltage or decelerating voltage between the electrode and the position sensitive type detector 12. The incident angle to the detector 12 is approximated to a square angle and the detecting sensitivity of the detector 12 is enhanced when the accelerating voltage is impressed. On the other hand, the intrusion of the scattered secondary electrons from the aperture 10, etc., into the detector 12 is prevented when the decelerating voltage is impressed. The time for measurement is, therefore, shortened.

Title: Delay circuit
Inventor: TANAKA HIROMICHI
IPC: H03K5/13
Filed: 1978-06-16
Abstract: PURPOSE:To stabilize the delay time when constituting the delay circuit via the charging and discharging of one capacitor by performing the level detection of the charging/discharging with stoppage of the charging/discharging and also setting the potential then to the initial level. CONSTITUTION:When transistor Q1 is ON, the collector potential is set lower than the ON-level of Schmitt circuit 4. Accordingly, both Q2 and Q3 are OFF. When Q1 becomes OFF with inversion of input signal Vin, the potential of capacitor C2 rises up. Thus the output of circuit 4 features a high level to turn on Q2 and Q3. The voltage of C2 is converged to the voltage which is divided by resistance R2, R3 and R4, and this voltage is set identical to the ON-level of circuit 4. As a result, the output is inverted to a high level and at the same time the charging is stopped. The similar procedure is given also in the case of discharging, and the charging/discharging is stopped simultaneously with the inversion. Thus, the delay time can be stabilized.

Abstract: PURPOSE: To manufacture a piston ring of excellent dimensional accuracy at low cost by making the shape of a sizing die a true circuler form in manufacturing a sintered alloy piston ring.  
     CONSTITUTION: An atomized iron powder is mixed with a lubricant powder, e.g., zinc stearate, natural praphite, etc., and then molded by compression in a molding die to form a pressed powder for piston ring, where the matching mouth of piston ring is made to have a dimension corresponding to 130W200% of a free matching mouth, and also the width dimension is set up by allowing for a 1W20% shrinkage allowance encountered in the subsequent process.

Title: Promoter for germination and rooting of plant
Inventor: SATO TAKASHI
IPC: A01N61/00
Filed: 1995-02-21
Abstract: PURPOSE: To obtain a readily handleable and simple promoter for gemination and rooting of plant having excellent synergistic effect and excellent economic efficiency and safety by blending pyrolignous acid consisting of an organic substance with an inorganic substance in a good mineral balance. CONSTITUTION: This promoter for germination and rooting of plant comprises pyrolignous acid and a mineral as active ingredients. Clay minerals as a combination of a natural mineral such as a montmorillonite mineral, illite and a kaolin mineral is preferable as the mineral. The mineral, for example, is obtained by dissolving the clay minerals directly in pyrolignous acid in an ionized state with organic acids as components of pyrolignous acid. When the promoter for germination and rooting of plant is applied to soil, since pyrolignous acid is readily permeated into organism tissue of a plant, etc., the mineral is efficiently absorbed in root parts.  The promoter for germination and rooting of plant activates activity of microorganisms in soil and promotes activity of root parts so that nutrition is smoothly absorbed and rooting of a plant is promoted by synergistic effects of both the components. Foliar absorption of the mineral is possible by foliar spray of a plant.

Accordingly when the laser 12 is manufactured onto the semiconductor substrate 11, the title device can be produced simultaneously, thus eliminating the need for the setting of a special manufacturing process.

Title: Tft substrate and its manufacture
Inventor: TOYODA MOTOHIRO
IPC: H01L21/336
Filed: 1997-03-25
Abstract: PROBLEM TO BE SOLVED: To improve the coverage of a gate insulating film and to simplify the manufacturing process by tapering the sidewall of a gate wiring at a gentle angle in a specific range and providing a gate insulating film formed without using anode oxidizing process. SOLUTION: On a metal film 2a, the gate wire 2 is formed in a gentle slope shape by dry etching so that the angle of its sidewall is 10 to 30 deg.. Namely, this gate wire 2 is tapered having no steep etched part on its sidewall, so an acutely angled part of the gate wire 2 need not be reduced by an anode oxidizing process unlike a conventional manufacturing method for a TFT substrate. Therefore, no anode-oxidized film is provided on the gate wire 2, so the step of the surface of the gate insulating film 5 can be made small. Further, the gate insulating film 5 only needs to be formed as a single layer by CVD, etc., right above the gate wire 2 after the patterning of the gate wire 2. Therefore, thus, the coverage of the gate insulating film 5 is improved to simplify the manufacturing process.

Title: Fluid vibration type flowmeter
Inventor: KUMAGAI MINORU
IPC: G01F1/20
Filed: 1999-03-17
Abstract: PROBLEM TO BE SOLVED: To provide a fluid vibration type flowmeter which can accurately measure a flow rate even when a change by a noise is carried on a normal fluid vibration. SOLUTION: This apparatus detects a flow rate Q based on a fluid vibration of a jet flow spouted to a dovmstream side passage 220 from a nozzle passage 210 and the downstream side passage 220 is provided with a pressure takeoff port 4 to detect the fluid vibration of the jet flow as differential pressure of a static pressure on both sides of the jet flow to determine a flow rate Q from a total range of change or an amplitude as changing value of the fluid vibration in a change in pressure detected by the pressure takeoff port 4. In other words, since the flow rate Q is not determined from the frequency of the fluid vibration of the change in pressure, the flow rate can be accurately measured even when a change in noise is carried on the normal fluid vibration (the change in pressure).
