IPC: H02P27/04
Filed: 1993-09-13
Abstract: PURPOSE:To improve torque control characteristics, at the same time facilitate sensorless speed control, and improve characteristics at a low speed region of an electric motor. CONSTITUTION:A speed command omegar* and a slip angular frequency omegas is added at a first addition part 11 to obtain a primary angular frequency omega at the output. The primary current of the electric motor is converted into a primary magnetic flux axis at a 3phi-dq conversion part 19 and then is input to a primary current axis constituent calculation part 20. Output i1gamma, i1delta, and i1gamma* of the calculation part 20 are given to gamma axis and delta axis ACR amplifiers 23 and 24 to obtain error voltage constituents DELTAV1gamma and DELTAV1delta at the output. Voltage command values V1gamma* and V1delta* obtained by multiplying the error voltage and omega by excitation current command value I0* are added by third and fourth addition parts 16 and 18 to obtain voltage commands V1gamma and V1delta given to a PWM circuit at the output.

Title: Method for joining different kind of metal material
Inventor: ENOMOTO MASATOSHI
IPC: B21K23/00
Filed: 1995-09-04
Abstract: PROBLEM TO BE SOLVED: To provide a method that enables partial joining of one member to the other by a simple means, that attains thickness for both members and that also excels in the joining strength (adhesion). SOLUTION: In joining two metal materials 1, 2 each with a different hardness, a large number of blind bite holes 3 are preliminarily formed on the joining surface of the hard metal material 2. The bite holes 3 are set to have the cross section larger than the opening part 3a at least in a part in the depth direction. With the joining surfaces superposed of both members 1, 2, the soft metal material 1 is deformed and bitten into the bite holes 3 fillingly by being pressed in the joining direction by forging. The bite holes 3 are desirably formed by the irradiation of an electron beam.

Title: Closing member with improved pull tab
Inventor: UORUTAA JIYOSEFU GIRURASU
IPC: B65D41/32
Filed: 1989-09-01
Abstract: PURPOSE: To effectively bond a closure member to a container near a pull tab with a reduced force by changing the shape of a neck of the pull tub so that the operating force pattern is formed on a bonding area crossing between the closure member and the container. CONSTITUTION: A pull tub 30 provides a finger hole 32, and is bonded to a closure member 16 by a neck 34 of which the width is reduced almost along a bonding line 36. The pull tub 30 has a V-shaped notch opened from the finger hole 32 toward the bonding line 36, and finished in front of the bonding line 36, which makes the pull tub 30 different from a conventional one. The neck of the pull tub 30 is definitely divided into two operating force supply parts 40, 42 by the notch 38. Accordingly when the operating force for removing the closure member is added to the pull tub 30, the neck 30 acts on the bond between the closure member and the container over almost the entire width of the neck, and the bond rupturing force added by the pull tub 30 is divided into two paths extending in the almost opposite directions in accordance with the lateral arrangement of the bond 26.

Abstract: PURPOSE: To make it possible to generate selectively the medical aerosol at an aspiration and to generate no waste of the medicine at an expiration, by having a sprayer generate aerosol at an aspiration in the patient's respiration cycle by the control signals generated by a sensor to react to a turbulence caused in an air current due to the patient's respiration. CONSTITUTION: A microphone 3 is placed at a position continuously connected to an air current passing through in the mouth piece, and set inside a chamber 4 having an opening 2 in a nearly parallel direction with the flow route of air current. The output from the microphone 3 is connected to a control circuit of the sprayer capable of being put into a port 1 of the mouth piece. When the microphone 3 detects a turbulence at an aspiration in the respiration cycle, a compressed air is fed into the sprayer via an inlet connector, as a solenoid valve controls it. This compressed air passes through the jet forming section 9 to collide with a bar 10 to generate a low pressure region to guide the fluid to the fluid jet forming section 12. The fluid coming out of this jet-forming section 9 is turned into fine particles by an edge 13.

Title: Manufacturing device for diffraction grating sheet
Inventor: OKAMURA MASANOBU
IPC: B29C59/04
Filed: 1990-08-28
Abstract: PURPOSE:To manufacture a large-screen diffraction grating sheet at a high speed by composing the device of an extrusion machine, a pair of an elastic roll and a cooling roll which are arranged right behind the extrusion die of the extrusion machine, and an endless stamper for diffraction grating embossment which is extended between the cooling roll and another roll. CONSTITUTION:The extrusion machine 3 extrudes fused resin from the extrusion die 31 into a film or sheet, the elastic roll 4 and cooling roll 1 are paired with each other, and the resin A right after being extruded from the die 31 and the stamper 2 are brought into contact with each other between both the rolls. The resin A right after being extruded is in a fused or softened state, so the unevenness of the surface of the stamper 2 for the diffraction grating is transferred to the resin surface. The stamper 2 is wound around the cooling roll to cool the surface of the resin A simultaneously with the unevenness formation so that the unevenness which is formed once is prevented from being lost owing to the flowability of the resin A. Consequently, the large screen diffraction grating sheet can be manufactured at a high speed.

Title: Disk autochanger
Inventor: SUGANO SHIGEKI
IPC: G11B17/22
Filed: 1994-09-22
Abstract: PURPOSE: To avoid misoperation by keeping power ON until an operation is finished when power is cut in a check mode for checking whether a disk is housed in a disk housing part or not and storing a result thereof. CONSTITUTION: A power switch 21 for the whole device is controlled for its OFF state even by a signal from a microcomputer 631 itself. In the main device, a power monitor flag is turned to '1' by switching power ON and when the power is switched OFF, this flag is reversed to '0'. When the flag is '1', since the power is kept ON, a standby mode is realized for receiving a next operation mode. On the other hand, when the flag is '0', if the power for the device is to be cut, it is controlled to be OFF. By incorporating such software, even when the device power is cut in the check mode, this check mode is continued and thus a complete data mapping is generated.

Filed: 1998-07-08
Abstract: PROBLEM TO BE SOLVED: To provide a temperature-controlling ventilation duct needing no power and capable of being fixed appropriately depending on the usage after a greenhouse is completed without having restriction of the strength of a fixing place and the structure of the green house. SOLUTION: A cylinder (duct) having a structure of two layers of vinyl chloride-made float rings is prepared, and a lid 2 is formed on the upper part and an adhesive face 5 is formed at the lower part. The cylinder is fixed in an air-evacuated state on a greenhouse with the adhesive face 5, then a hole for placing the duct is opened, and the duct is attached. After the attachment, air is introduced to bloat the duct by air pressure. The duct is so light that special strength is not needed for supporting the duct at the fixing place; and when it is fixed at a curved place, the first stage is curved following the curvature of the place and the second stage absorbs the curving, and thus owing to the two-stage structure, the duct-body is closely adhered to the lid 2. Ventilation is performed by ascending current and convection current without needing power.
