Title: Key telephone system
Inventor: SUZUKI MASAAKI
IPC: H04Q3/58
Filed: 1992-01-31
Abstract: PURPOSE:To generate an incoming sound from the telephone set in synchronism with the intermittent pattern of an incoming signal from a telephone line. CONSTITUTION:An incoming detection circuit 9 detects an incoming signal from a telephone line 6 and a conversion circuit 11 converts it into a digital code in synchronism with the intermittent pattern. A code insertion circuit 12 to be connected to a basic interface circuit 3 inserts the digital codes into an additional control bit, or a code superimpose circuit 10 superimposes it to B channel 7 of the ISDN, sending the code through a basic interface 4 to a telephone set 5. The telephone set 5 sends a digital code through a code extraction circuit 14 to an intermittent circuit 17. The circuit 17 is in synchronism with the digital code to intermittently send an incoming sound signal from an incoming signal sound source 15. The signal is sent to a speaker 16, which generates an incoming sound as an audible sound.

Title: Compound type diaphragm
Inventor: MORI TOORU
IPC: H04R7/14
Filed: 1978-04-12
Abstract: PURPOSE:To prevent the occurrence of split vibrations by laminating an auxiliary diaphragm and a main diaphragm. CONSTITUTION:This is the compound type diaphragm laminated with two sheets of a main diaphragm 9 having no corrugations 4 and a diaphragm 10 provided with the corrugations 4 or ribs. Such constitution improves bending rigidity without increasing the thicknesses of the respective diaphragms, i.e., supresses symmetrical vibrations with the main diaphragm 9 having no corrugations 4. Further the non- symmetrical vibrations are suppressed with the auxiliary diaphragm 10 having the corrugations 4, thus the speaker diaphragm of a wide reproducing frequency band may be formed.

Abstract: PURPOSE:To prevent the occurrence of mulfunction and to prevent the occurrence of a reverse roll phenomenon which presents itself during shifting to straight running from turning, by a method wherein a flow rate regulating valve is controlled so that a car height is controlled to a set value by means of an electric signal. CONSTITUTION:A low pressure fluid chamber 3 is formed between an outer cylinder 1 and an inner cylinder 2 which both serve as a cylinder. A high pressure fluid chamber 7 is formed between a partition 4, which is positioned to that the openings at the two ends of the outer and inner cylinders 1 and 2 are closed, and a cover body 1. A 2-position solenoid valve 28, serving as a flow rate control valve, is located in communicating passages 29 and 30 through which the high pressure fluid chamber 7 and the low pressure fluid chamber 3 are intercommunicated, is brought into a shut-off and a communicating condition by means of valve driving signals (a) and (b). A pressure signal P from a pressure sensor 24 of the fluid chamber 7 is compared with ideal pressure signals P10 and P20. When P exceeds the ideal pressure signal, it is decided that a car height is too increased, and a car height is decreased by outputting the valve driving signal (a) so that the 2-position solenoid valve 28 is opened.

Title: Magnetic wedge for motor
Inventor: SATO TADAYUKI
IPC: H02K3/487
Filed: 1991-03-08
Abstract: PURPOSE:To enhance adhesion strength of magnetic film by thermally spraying a material having thermal expansion coefficient close to that of the magnetic film onto the irregular surface of a thin nonmagnetic member for forming a magnetic wedge of motor and then thermally spraying a magnetic material thereon. CONSTITUTION:A semi-closed slot 12 is made in a stator 11 and a coil 13 is contained therein. A magnetic wedge 15 is inserted into an opening 14 in order to prevent the coil 13 from springing out of the slot 12. Irregular face is then formed on a thin nonmagnetic member 16 for the magnetic wedge 15 by means of shot blast or embossing. A ceramic material 20 having thermal expansion coefficient close to that of the thin nonmagnetic member 16 is then thermally sprayed on the irregular face followed by thermal spray of a magnetic material thereon thus forming a magnetic film 17. Ceramic 20 has high melting point but thermal capacity thereof is low at the time of thermal spray and thereby direct thermal spray onto the thin nonmagnetic member 16 causes little thermal influence thereon. Consequently, when the magnetic material is thermally sprayed thereon, difference of thermal expansion the thin nonmagnetic member 16 is low resulting in the enhancement of adhesion strength.

Title: Detecting method for defect and foreign matter in magnetic material
Inventor: KAKIMOTO AKIHIRO
IPC: G01N27/83
Filed: 1986-02-28
Abstract: PURPOSE:To detect a defect even in a magnetic material which is even moving at a high speed by arranging a coil in a stationary magnetic field and running the magnetic material through the coil in the direction of the magnetic field. CONSTITUTION:When the magnetic material 1 has neither a defect nor mixed foreign matter and is homogeneous, magnetic flux phi penetrating the magnetic material is uniform on its surface and inside. No leak magnetic flux is produced on the surface of the magnetic materials 1 and even when the magnetic material 1 runs at a speed V, the magnetic flux penetrating the coil 2 has no variation and no electromotive force is generated at the coil 2. If the magnetic material 1 has a defect part 5, this part 5 increases in magnetic resistance, so the magnetic flux becomes hard to pass as compared as other parts. Therefore, leak magnetic flux DELTAphi is produced on the surface of the magnetic material 1 at the part 5 and the coil penetrating magnetic flux varies corresponding to the magnetic flux DELTAphi at time DELTAt when the part 5 passes through the coil 2. Therefore, a voltage E shown by an equation (where N is the number of turns of the coil) is outputted from the coil 2.
