Title: Method for providing segmented thin fibrous body to container made of thin synthetic resin sheet
Inventor: YOSHIDA KATSUMI
IPC: B65D77/32
Filed: 1988-02-28
Abstract: PURPOSE:To apply a segmented thin fibrous body material to a hinge tensely at low cost by a method wherein the hinge is made of a thermally-fusable material and a segmented thin fibrous body material which has been excessively twisted is provided on the inner and outer sides of the hinge and both ends are thermally-fused. CONSTITUTION:At the time of providing a segmented thin fibrous body material 5 in a loop shape on a hinge 4, the material 5 is made of a thermally-fusable material such as synthetic resin, and after said material 5 is excessively twisted, it is wound around the hinge 4 of a container 1 with its lid open and the ends are thermally-fused 7 by being pressed by a pair of heat plates 6. Since said material 5 itself has been excessively twisted, a twisted part 8 made of two materials twisted into one is naturally formed on some part of the segmented thin material 5, permitting the material 5 to be attached to the hinge 4 tensely without slack. Since the material is fused into a loop, it permits immediate bonding, thereby the segmented thin material can be attached at low cost.

Title: Method for measuring depth of snowfall
Inventor: NAGAYA YASUSHI
IPC: G01W1/14
Filed: 1996-02-08
Abstract: PROBLEM TO BE SOLVED: To measure snowfall accurately by providing a temperature sensor and a control circuit and correcting the velocity of ultrasonic sound propagating through the air based on the average value of temperature sensor. SOLUTION: Outputs from temperature sensors 4, 5 are converted 6, 7 into voltages which are then converted 8, 9 into digital signals. Two temperature outputs are averaged through an averaging circuit 10. Velocity of ultrasonic wave propagating through the air is then calculated 11 from the average value for the average temperature and an output corresponding to the sound velocity is fed to a control circuit 14. On the other hand, output from an ultrasonic transmitter/receiver 3 is amplified 13a and converted 13b into a digital signal before being inputted to the circuit 14. Since the circuit 14 performs operation based on the results obtained by operating 11 the output from a wave receiving system 13, it can produce a corrected output insusceptible to the temperature difference between high and low temperature parts in the daytime and night.  Consequently, the accurate position of snow surface that is the depth of snowfall can be obtained.

Title: Multistage amplifier of microwave band
Inventor: ANDOU MASAKI
IPC: H03F3/60
Filed: 1979-04-14
Abstract: PURPOSE:To obtain a stable I/O characteristic by providing a filter, which causes a desired frequency to pass through, in one position, at least, between amplifiers in a circuit where microwave band reflection amplifiers are cascaded in multistages. CONSTITUTION:Circulator SC1 and diode mount DM3 constitute a reflection amplifier, and circulator SC2 and diode mount DM4 constitute a reflection amplifier also. Meanwhile, LPF9 where the signal frequency band passes and the twice or more frequency band is stopped is connected between the first-stage amplifier and the next-stage amplifier. Then, the higher harmonic generated from the diode of each stage is reflected by LPF9 and is prevented from having influence between the first-stage amplifier and the next-stage amplifier. Therefore, a stable characteristic can be obtained for the amplification operation independently of the quantity of the higher harmonic generated from each stage.

Title: Motor control circuit
Inventor: SOYA TAKASHI
IPC: H02P29/00
Filed: 1990-02-28
Abstract: PURPOSE:To improve frequency response of a control system by varying the load of a rotational speed/voltage converting means according to the difference of rotational speed between a control target motor and a current motor thereby providing the motor with brake function. CONSTITUTION:When the output from an operational amplifier 103 varies in the negative direction, resistance between drain and source of an n-channel junction FET 104 increases. In other words, load on a tachogenerator 214 decreases at the time of acceleration of a motor. When the rotational speed of a motor 213 is higher than a target level, output voltage from an operational amplifier 207 varies in the negative direction and power supply to the motor is decreased. At this time, output from the operational amplifier 103 varies in the positive direction and the resistance between the drain and the source of the n-channel junction FET 104 decreases. In other words, load on the tachogenerator 214 increases at the time of deceleration of the motor.

Title: Semiconductor device
Inventor: MATSUNAGA TAKAKO
IPC: H01L29/866
Filed: 1990-02-26
Abstract: PURPOSE:To protect the supply without requiring a wide space by letting between the first formation layer and the second formation layer, which is made so as to pass through an epitaxial layer, function as a Zener diode while making good use of the second formation layer. CONSTITUTION:Since the positive supply is applied to a VDD interconnection 1 and the negative one to a VSS interconnection 2 under normal conditions, an N-type epitaxial layer 4 is joined and separated by a deep P<+>-type area 3. At this time, the deep P<+>-type area 3 and an N<+>-type area 8 are doped in high density and so they usually offer a Zener effect and work so that more voltage may not be applied between the VDD interconnection 1 and the VSS interconnection 2 than specified. When the voltage applied between the VDD interconnection 1 and the VSS interconnection 2 becomes reversed polar, these two areas lets a forward current flow and work so that the reversed polar voltage may not be applied to an inside circuit. Consequently, protection is performed enough, adjustments is easily made to a Zener voltage structurally and only a small area is required for a chip since the deep P<+> area is formed vertically.

Abstract: PURPOSE:To control the rise in initial pressure when the turning of a motor is stopped by a mechanism in which a switch device by which the drain circuit of a vent relief valve provided to a flow rate control valve for a construction machinery is opened only when an arm cylinder operates excavation is provided on the side of a spool for the arm. CONSTITUTION:When a bucket is turned while pressing it on the side wall of trench, a motor 3 does not turn and pressure oil from a pump p does not flow to a motor path 16. Accordingly, the pressure on the supply side of the motor 3 is increased up to a relief set pressure to cause a pressure drop, but a switcher 47 is connected to annular chambers 48 and 50 and the oil chamber 40 of a vent relief valve 38 is connected to a tank T, making it a tank pressure. Then, a poppet 43 is opened against a spring 42 by means of a pressure difference between a control chamber 31 and the oil chamber 40 to cause a difference in pressure between the control chambers 31 and 32. A spool 28 is controlled toward the left position and pressure oil at the inlet the port 10 is flowed to the arm side through a side path 13b and bypass 12. Thus, high pressure on the supply side of the motor 3 and in the side path 13a becomes lower than the relief set value and wastefull loss of energy can be prevented.

The array 111 thus formed is repeatedly disposed as designated by 113, 114 at an interval required with each other in a direction 112 perpendicular to the axis 109. Thus, an LSI is largely integrated so that, the larger the LSI is arrayed, the number of the space transistors at the transistor array end becomes substantially constant in mean value and one space transistor is created only in case that the circuit block using odd transistors is aligned in a direction of odd arrays.
