Title: Joint of culvert
Inventor: MASAKA KOSEI
IPC: F16L27/10
Filed: 1996-11-26
Abstract: PROBLEM TO BE SOLVED: To prevent swelling due to the external water pressure by attaching a return keeping sheet to a flexible sheet in the vicinity of a return part where a part of the flexible sheet is returned. SOLUTION: When water enters from the outside of culverts 2, 2' through a joint 6 in a normal condition, return keeping sheets 12, 12' are not peeled by the tension of a flexible sheet 3 of an extension part 4 of a joint 1, and the returned condition of the flexible sheet 3 at return parts 10, 10' can be kept. When the culverts 2, 2' are relatively displaced in the direction to be separated from each other by an earthquake, etc., the adhesion between the return keeping sheets 12, 12' and the flexible sheet 3 is broken. The return keeping sheets 12, 12' are simultaneously or successively separated from the flexible sheet 3, and the sheet 3 is disentangled, the return parts 10, 10' are extended to absorb the relative displacement. Thus, the extension part 4 can be prevented from swelling to the inner circumferential side of the culverts 2, 2' by the external water pressure.

Filed: 1988-12-29
Abstract: PURPOSE:To provide a cosmetic container composed of a resin only, having glossy surface, free from the exposed glass fiber and air bubbles by using the metal dies employed in the molding of the container with their shaping surfaces preheated to a temperature higher than the deformation-causing temperature of thermoplastic resins. CONSTITUTION:A high-frequency oscillator 5 produces high-frequency current to generate eddy current on the shaping surfaces of metal dies in order to heat the same. The oscillator 5 of 50 - 70KW is employed which is capable of heating the shaping surfaces preheated to 60 - 80 deg.C by a heater to 100 - 130 deg.C with the oscillation time set at 5 - 10sec. After heating the shaping surfaces at least to 100 deg.C in this way, a cylinder 4 is actuated to remove a heater coil 3 from between metal dies 1 and 2 and, at the same time, the dies are closed. The thermoplastic resins (containing glass fiber or air bubbles due to foaming agent) heated at 180 - 260 deg.C into a molten state is injected into the dies from an injection device 6 and allowed to stand for predetermined hours for cooling. The dies are thereafter opened to take out the molded container.

Title: Controller for pulse-width modulation inverter
Inventor: TERUNUMA MUTSUHIRO
IPC: H02M7/497
Filed: 1993-12-27
Abstract: PURPOSE:To smoothly perform switching between asynchronous modulation and synchronous modulation and continuously control the output voltage of a pulse-width modulation inverter in a whole area so that a comfortable ride can be obtained by adjusting the phase angle of a basic modulated wave at the time of switching the control between multiple-pulse control and one-pulse control. CONSTITUTION:A three-level inverter is provided with a means which outputs a pulse- width-modulated signal synchronized with the modulated-wave signal of the inverter is provided for one-pulse control under which the inverter outputs the highest voltage and a means which outputs a pulse-width-modulated signal asynchronous to the modulated-wave signal of the inverter for multiple-pulse control other than the one- pulse control. The pulse-width modulated signal synchronous with the modulated-wave signal of the inverter under the one-pulse control is formed so that the turn-on or turn-off phase angle of the signal can become coincident with that of a basic modulated wave. The pulse-width-modulated signal asynchronous with the modulated-wave signal of the inverter under the multiple-pulse control is formed so that the turn-on or turn-off phase of the signal can become coincident with that of the commanding value of an instantaneous voltage to be outputted.

Title: Printing method for long continuous pattern
Inventor: TERADA YUKIO
IPC: B41M3/00
Filed: 1987-12-25
Abstract: PURPOSE:To enable continuous printing without particularly strict registering, by a method wherein both end parts of a single unit pattern for printing a continuous pattern are printed by alternately using, in an overlapping manner, two kinds of halftone dots with dot density gradually reduced continuously. CONSTITUTION:For example, a printing material 4 is moved between an impression cylinder 1 and a blanket 2, and 8 printing ink is transferred from a plate 3 to the printing material 4 through the blanket 2, resulting in printing. At the first printing unit 5, printing in yellow is conducted by a conventional method while using halftone dots at an end part of a pattern. In the pattern thus printed by the first unit 5, the end part 7 has a printed density gradually lowered. Next, at the second unit 5', a unit pattern is printed while overlappingly printing the end part 7' in the same yellow color by using halftone dots with dot density varied oppositely to the above. Thus, the second end part 7' printed with a gradually increasing density overlaps with the first printed part, resulting in a predetermined printed density as a whole. Further, the same process is repeated at the third and latter units.

Later, another insulating film 6 is formed by the low temperature CVD step (e.g. thermal CVD, photo CVD, plasma CVD etc.) not exceeding 800 deg.C further to be annealed or oxidized at a high temperature exceeding 800 deg.C. At this time, the CVD SiO2 works as a barrier to prevent Mo from permeating into the Si substrate 1 for covering the periphery of the gate electrode with a thermal oxide film 7. Through these procedures, the IC in high reliability developing no crystal defect can be manufactured.

Patent JP-H04199158-A (JP)
Title: Image forming device
Inventor: TANIMOTO YASUFUMI
IPC: G03G21/00
Filed: 1990-11-29
Abstract: PURPOSE:To facilitate the detection of the loading of a process unit and to enhance reliability on the detection by detecting voltage drop at the time of driving a pre-exposing means and detecting the loading of the process unit in a device main body based on the detection output. CONSTITUTION:When '0' is outputted as an output signal (1), the transistor(Tr) Q2 of a lamp driving circuit is turned on. In the case that the process unit 60 is not loaded in the main body at such a time, the Tr Q2 is saturated. Since a current I1 which flows in a resistance R6 is low and the voltage drop by the resistance R6 is small, a Tr Q3 is not driven with reference voltage Vref2. Therefore, the reference voltage of comparators IC1 and IC2 really becomes just lamp driving voltage VDD, and the output of the IC1 becomes '1' and the output of the IC2 becomes '0'. Since an AND circuit consisting of capacitors D1 and D2 does not hold, in such a case, a Tr Q4 is kept to be off and a detection output signal (2) to an engine control circuit 70 becomes '1', then the circuit 70 decides that the unit 60 is not loaded. When the signal (2) is '0', the circuit 70 decides that it is loaded.
