IPC: A01K89/015
Filed: 1997-08-12
Abstract: PROBLEM TO BE SOLVED: To provide a device capable of surely stopping the delivery of a main line at a set fish swimming layer without causing great shocks to a spool. SOLUTION: This device is equipped with a spool around which a main line is wound, a motor for driving the spool, a detecting means for detecting the rotational frequency of the spool, an arithmetic unit for performing the computing treatment of a signal from the detecting means, an inputting means for designating the stopping position of the spool at the time of delivering the main line and a memory for storing the rotational frequency or the input from the inputting means. The rotational frequency of the spool at a specific main line delivering depth is stored and an informing signal is outputted when the cumulative rotational frequency coincides with the stored rotational frequency by starting from a state in which the cumulative rotational frequency of the spool at the actual main line delivering position is lower than the stored rotational frequency.  The main line is wound up by winding up thereof with the motor until the cumulative rotational frequency coincides with the stored rotational frequency when the delivery of the main line exceeds the stored rotational frequency and the spool is forcibly stopped.

Title: Manufacture of semiconductor device
Inventor: MUKAI RYOICHI
IPC: H01L29/80
Filed: 1989-09-08
Abstract: PURPOSE:To enable creation of an emitter part with a sharp tip with a stable process by accumulating a gate material and a collector material on a substrate through an insulation film, opening an emitter part, and by enabling the emitter part to be subjected to gaseous phase growth by irradiation with light. CONSTITUTION:An insulation film 12a is allowed to grow on an SOI substrate 11, tantalum is allowed to grow by 1mum as a material for a gate 13 successively, and tantalum is allowed to grow by 1mum with an insulation film (silicon oxide) 12b as a material for a collector 14. After coating a resist, a hole 17 which becomes an emitter-forming part reaching the SOI substrate 11 is partially formed. While Si2H6 is allowed to flow as a raw material gas of emitter at 50cc/min., light of a mercury lamp 15 is projected. At this time, the temperature of a part of the hole 17 increases since the SOI substrate 11 is exposed and horizontal heat dissipation occurs at a part where the hole 17 is in contact with the surrounding, thus decreasing the temperature. The center of the hole 17 is hottest due to accumulated heat and forms a temperature gradient toward the periphery. Then, since accumulation rate reflects the temperature inclination of the SOI substrate 11, an emitter 16 of Si in conical shape is accumulated and formed.

Title: Production of pigment for ceramics
Inventor: NISHIHARA AKIRA
IPC: C04B41/86
Filed: 1987-09-18
Abstract: PURPOSE:To obtain pigments of excellent heat resistance for ceramics by heat- treating Cd pigments for ceramics which is coated with a heat-resistant substance in air, and washing the products with an acid. CONSTITUTION:In the production of a cadmium pigment of excellent heat resistance for ceramics by removing insufficiently coated pigment particles from the pigment coated with a heat-resistant substance, the pigment is heat-treated in air at 100-350 deg.C beforehand. In the acid rinsing, the pigment is first treated with nitric acid, then with hydrochloric or sulfuric acid, or with a mixture of nitric and hydrochloric acids or nitric and sulfuric acids. The concentration of these acids is over 5%, preferably 10-20% in the acid rinsing. When the concentration is lower than 5%, rinsing effect is too low, while in case of over 20%, the alkalis in the coating material of the pigment or fritts becomes readily soluble, resulting in reduction in protection of the Cd pigments from oxidation.

Abstract: PROBLEM TO BE SOLVED: To make a driver simpler by connecting an impedance between the input of a voltage buffer which inputs current pulse signals and a potential which is lower than the low level of a first voltage pulse signal. SOLUTION: The collector, base, and emitter of a first NPN transistor 8 are respectively connected to a fifth power source 25, the base of a first PNP transistor 9, and the driver output terminal 11 of a voltage pulse having a low-level potential V3. In addition, a first resistor 7 is connected to the base of the first PNP transistor 9 and a third power source 10. In this way, an input voltage pulse having a reference potential V1 is converted into a voltage pulse having another reference potential V3 and the high level of an output pulse is arbitrarily set by the resistance value of the first resistor 7. Consequently, the number of parts used in a driver circuit can be reduced and the circuit can be constituted easily in an integrated circuit, because the circuit can be constituted only of transistors, diodes, and resistors.

Filed: 1991-08-21
Abstract: PURPOSE:To surely detect a pressing operation with a coordinate detector without using any circuit for the detection of a pressing operation by using an A/D converter used for the detection of the positions. CONSTITUTION:The X and Y resistance plates 1 and 2 are arranged opposite to each other. The DC voltage is applied to the high potential side 2A of the plate 2 before the detection of a pressing operation is started with the low potential side 2B kept inconductive and the plate 2 kept at a high potential respectively. A press detecting resistor 3R is connected to the low potential side 1B of the plate 1 for which no voltage is applied via a switch SW1. Then an A/D converter 3 is connected in the halfway of the connection between the side 1B and the resistance 3R via switch SW2. When a pressing operation is applied to the plate 2 where the DC voltage +V1 is applied, the current flows to the side 1B from the pressed position via the plate 1. Then the current flows through the resistor 3R via the SW1 to generate the voltage of a fixed level. This voltage is inputted to the converter 3 via the SW2 for the detection of the pressing operation.

Abstract: PURPOSE:To obtain a timepiece whose thickness is small with an excellent fashion property, by a method wherein an ultrasonic motor rotating a time indicating hand is controlled by an output signal of a time counting element, so that the indicating hand be advanced to a prescribed position. CONSTITUTION:A drive power source 22 of an ultrasonic motor 12 is a source of a two-phase AC voltage of motor drive frequencies, and it outputs voltages V1 and V2 of two phases which are sine, rectangular or triangular waves and different in a phase of 90 deg. from each other. Either one of these voltages V1 and V2 is connected directly to a terminal of the motor 12 to excite two poles out of four, and the other is distributed to fifty-nine contacts of sixty in a group on a watch face through a distributor 23, the remaining one being earthed. This earthed contact shifts along a string of the sixty contacts clockwise in a sequential manner in synchronism with a clock pulse of 'minute' of a digital watch 21. When the time of the watch 21 shifts from 59min to 0, the earthed contact shifts on the watch face in synchronism with the hour hand of the watch 21. When the central hole of a minute hand plate is set on the outer periphery of the motor 12, the minute hand plate stops at a position indicating the present time. Thereafter the minute hand shifts in synchronism with the clock pulse.
