Title: Diaphragm used for speaker, diaphragm edge and dustproof cover
Inventor: SHINGU FUMITERU
IPC: H04R7/02
Filed: 1994-04-08
Abstract: PURPOSE:To obtain the air cut-off characteristic, uniform adjustability of coloring and lightness of base material by welding a thermoplastic polyurethane resin film to base material, laminating the films, performing a heating and shaping molding for base material, forming the material into a multilayer structure and sealing the texture of a cloth body. CONSTITUTION:In diaphragms 5 and 5', the both surfaces or one-side surface of base material 1 which is made of a cloth body as main material and for which an automorphic processing is performed is formed into a multilayer structure and the sealing the texture of the cloth body is performed by performing a heating formation into a required shape such as a dome shape, etc., after a thermoplastic synthetic resin film 2 such as a polyurethan resin film is heated, is welded to the base material and is laminated at the time of an inspection after the film is adhered to the base material by adhesive. Therefore, because the generation of the pin hole in formed products at the time of the automorphic working of the base material 1 is prevented, accoustic radiation efficiency is not lowered and the influence of the cloth texture of the base material is not received, a diaphragm 5, a diaphragm edge and a dustproof cover which are excellent in color development can be formed.

Title: Switching power unit
Inventor: SATO MITSUO
IPC: H02M3/28
Filed: 1995-04-20
Abstract: PURPOSE: To use a device both in normal mode and in power saving mode by inputting the switching signal from a switch into a control part through a photocoupler, and switching the oscillation frequency of a switching circuit. CONSTITUTION: One of secondary DC output circuits is provided with an error amplifier 38 which detects the ripple on the DC voltage, and the output circuit of the detection signal is connected to the input side of a photocoupler 42. Moreover, at the time of switching an operation mode, the switching signal in power saving mode from a switch 20 is inputted into a control part 33 through a photocoupler 42, and the control part 33 controls the oscillation frequency of the switching circuit 2 to lower the secondary outputs 8 and 9 and switch it into power saving mode. Furthermore, when overvoltage is generated in the Zener diodes 21, 22, and 23 provided severally in the DC output circuits, a detection signal is inputted into the control part 33 by the feedback circuit using a photocoupler 31 so as to stop the oscillation of the switching circuit 2.  Hereby, the breakdown by the overvoltage of the parts connected to the secondary output circuit can be prevented.

Title: Superconductive coil exciting current controller
Inventor: KAMIYAMA KENZO
IPC: H02P9/30
Filed: 1985-05-04
Abstract: PURPOSE:To prevent a superconductive state from damaging by suppressing a current change rate flowing to a superconductive lead to the prescribed range. CONSTITUTION:A voltage controller VC calculates the difference between a command value Vrr from a voltage setter REF and the detected value Vrb of the output voltage of an armature GEN to obtain a field current change rage command Vrr. Further, the difference between the command Vrr and the differentiated value formed by processing a field current detected value Vcb detected by a field current detector SH is calculated to obtain an input signal Vc for a gate pulse generator GPG. A DC variable current necessary for the field coil FLD is supplied according to the signal Vc to regulate the output voltage of the armature GEN to a set value. Thus, the exciting current is controlled at the change rate of the maximum allowable limit without damaging the superconductive state of a superconductive coil.

Filed: 1984-05-14
Abstract: PURPOSE:To attain rapidly and easily required ''kana'' (Japanese syllabary)/ ''kanji'' (Chinese character) conversion by forming an extending conversion key, and when ''kana''/''kanji'' conversion is to be executed in each clause, dividing each clause into a stem part and an adjunct part and executing the ''kana''/ ''kanji'' conversion independently in each part. CONSTITUTION:If an unrequired part is included in a document converted from ''kana'' to ''kanji'' in each clause and displayed on a display 6, the stem part is processed by a conversion key on a keyboard 1 and the adjunct part is processed by the extending conversion key on the keyboard 1. Namely, the extending conversion key arranged on the keyboard 1 is depressed to convert the unrequired adjunct part into a required ''kanji'' senstence or ''kana''-''kanji'' mixed sentence. Consequently, an extending conversion key signal is informed from a ''kana''/''kanji'' conversion part 3 to an adjunct memory 10, which displays a ''kanji'' character or ''kana''-''kanji'' mixed sentense located in the succeeding order which corresponds to the adjunct part on the display 6. Thus, the arrangement of the extending conversion key makes it possible to execute rapidly and easily the required ''kana''/''kanji'' conversion.

Title: Thermograph method for determining volume of concrete in mixing container
Inventor: JIYON OO DEMAASU
IPC: G01F23/22
Filed: 1992-03-24
Abstract: PURPOSE: To easily but accurately measure the volume of concrete in a concrete mixing drum by sticking a strip of a thermographic material to the external surface of the drum and observing the boundary formed on the material caused by the temperature difference between the concrete and the air above the concrete. CONSTITUTION: A thermographic strip 2 is stuck to the external surface of a concrete mixing drum 3. Since the strip sections 4 and 5 are colored in different colors due to the heat characteristics of the concrete and air above the concrete, the level of the concrete in the cement mixer 1 can be decided by observing the boundary 6 between the different colors 4 and 5. Then the volume of the concrete in the mixer 1 is decided by putting the level on a volume indicating scale. Therefore, the volume of the concrete in the mixer 1 can be measured easily with accuracy and can be used for deciding the adding quantity of an additive.

Title: Ultrasonic bearing
Inventor: IGARASHI KENJI
IPC: F16C27/02
Filed: 1988-04-21
Abstract: PURPOSE:To reduce the size of a bearing by applying ultrasonic vibration to a bearing hole to create an approximately non-contact bearing condition in an ultrasonic bearings loaded on various general domestic information apparatus. CONSTITUTION:A bearing comprises a plate-like support portion 1, a piezoelectric element 2 fitted to one end portion of the support portion 1, and a power supply 3 for applying a.c. voltage to the piezoelectric element 2. On the other hand, a cylindrical shaft 10 is inserted in a round hole 4 of the support portion l in such a manner as to freely turn on the shaft center. In this arrangement, when a.c. voltage having the frequency of about 30k-50kHz is applied to the piezoelectric element 2 by the power supply 3, the inner wall surface of the round hole 4 is micro-vibrated in an ultrasonic wave range having about 30k -50kHz. The acceleration at this time corresponds to several hundreds times as much as the gravity. Accordingly, the shaft 10 can not follow a change of the inner wall surface of the round hole 4 to be apparently out of contact therewith. Thus, a smooth bearing having no friction can be obtained. In this case, it is not necessary to provide a large device for supplying a fluid so as to reduce the size of the bearing.
