Title: Electric acoustic converter and loudspeaker
Inventor: BOOTSU IRIIRI
IPC: H04R9/06
Filed: 1989-05-31
Abstract: PURPOSE: To increase the sound volume by forming a non-obedient electrically insulated layer between an acoustic discharge element and a pole piece. CONSTITUTION: A pole piece 4 has a non-obedient electrically insulated layer 16 (including a skirt 13), and the entire inner surface of a dome 11 includes a non-obedient electrically insulated layer 18. Both layers 16 and 18 are formed into the extremely thin but rough electrically insulated layers by a coating or metallic finishing treatment. Then both layers 16 and 18 are placed on the piece 4 and the inner surface of the dome 11, so that a clearance gap 14 is minimized between the skirt 13 and the piece 4 and also a dangerous electric short circuit is never caused between the dome 11 and the piece 4. Thus, the acoustic output of the dome 11 is increased.

Title: Card system electric lock
Inventor: NAGAI KAZUHIKO
IPC: E05B49/00
Filed: 1990-05-24
Abstract: PURPOSE:To simplify the card management by composing the system by specifying the code data as the standard data to permit or prohibit the unlocking of an electric lock only when a key card is inserted in an insertion hole, and making only that card effective. CONSTITUTION:When a key card with a pecuriar code data is inserted in an insertion hole in the unlocking time, the data is read and stored in the RAM 31, and the CPU 32 drives a lock driver 36 and locks up. And, when the card is inserted again and the code data is coincident with the data in the RAM 31, the lock is released to open the door, and the code data stored in the RAM 31 is eraced. And, when a master card or a key is inserted, the lock is released and the data is eraced. As a result, by preparing only numerous cards with pecuriar data of the different cards, other than the pecuriar data for a specific room, the card management can be carried out easily.

Title: Multi-layer integrated circuit device
Inventor: HIRABAYASHI KANJI
IPC: H01L27/12
Filed: 1981-08-31
Abstract: PURPOSE:To facilitate the formation of wiring within a layer and between layers with short wires by using an inclined surface in tiers provided between semiconductor layers in a plurality of layers as a wiring region. CONSTITUTION:In each semiconductor layer, contacts are arranged for wiring within the layer and between layers on a tiered surface outside a semiconductor layer to be laid on top of the preceeding semiconductor layer. In so doing, after the laminated semiconductor layer is formed, wiring within the layer 3 and between the layers 4 can be formed by utilizing each of the tier surfaces of the inclined ones. As a result, it becomes possible not only to reduce an area exclusively occupied by the circuit three-dimensionally integrated but also to realize wiring within the layer and between the layers with short wires by using the inclined surface in tiers. Moreover, because the inclined surface in tiers is utilized for wiring and because wiring within the layer and between the layers can be collectively completed after the laminated semiconductor layer is formed, the manufacturing process is simplified.

Title: Hollow cathode discharger
Inventor: MORIMIYA OSAMU
IPC: H01J1/02
Filed: 1979-10-23
Abstract: PURPOSE: To stabilize the starting of discharge and the steady discharge by varying the gas pressure in a hollow cathode at the start of discharge and during steady discharge.  
     CONSTITUTION: At the start of discharge, open/close valves 14, 16 are opened to supply the gas stored at a gas storage 11 through fluid circuits 12, 13 into a cathode 2. Consequently the gas density in the cathode 2 at the start of discharge is increased. High voltage pulse is applied between the cathode 2 and a start electrode 6 at the start of discharge to produce the discharge between each electrodes 2, 6. Consequently the starting of hollow cathode arc discharge between the cathode 2 and anode 3 can be performed stably and reliably. During steady discharge the open/close valve 16 is closed to lower the gas density in the cathode 2 to maintain stable hollow cathode arc discharge.

Filed: 1998-05-19
Abstract: PROBLEM TO BE SOLVED: To provide the drive circuit of an actuator comprising a piezoelectric element to be capable of keeping the rising time and falling time of actuator driving almost constant regardless of applied drive voltage.

Title: Error rate supervisory system
Inventor: MIYAMOTO BUNICHI
IPC: H04L1/00
Filed: 1979-10-23
Abstract: PURPOSE:To eliminate influences of the residual pattern jitters and timing, by converting a noise component proportional to an input noise component into a thermal noise from a different noise generator and then by applying it to a base-band demodulated signal. CONSTITUTION:Noise generator 25 generates a pure white signal of the same frequency band with noise component g'' outputted from filter 18 and AGC amplifier 26 amplifies it. Noise component g'' detected by detectors 23 and 24 and the noise component from generator 25 are supplied to comparator 29 for a level comparison and its error output is negatively fed back to amplifier 26. As a result, noise converting circuit 30 generates a pure white noise output which varies in level with component g''. Then, the output, after being adjusted to a proper level by attenuator 19, is applied as noise component g' to adder 20 and added to demodulated band signal (b) or (c) to obtain a base band signal with the noise component increased. Consequently, component g' never has the residual pattern jitters and timing components such as component g''.

IPC: B24B49/02
Filed: 1993-06-08
Abstract: PURPOSE:To provide a method and device for on-line grinding a roll with which the initial profile is recovered without interrupting rolling operation and the roll life is prolonged. CONSTITUTION:The profiles of work rolls 1a, 1b-4a, 4b of each roll stand are measured with measuring devices 11a, 11b. These measured profiles are compared with the target profiles which are preliminarily stored in a storing means 13 with the grinding controlling means 12 and, when the abrasive loss of the work roll is smaller than the allowance that bending is controllable and exceeds a specified amount, roll grinding devices 10a, 10b which are incorporated in each stand are controlled so as to grind this specified amount during rolling. In this way, the noncontact parts of the work rolls are ground. On the other hand, grinding according to the target profile including contact parts is executed at the idle time of the rolling mill. This grinding timing is unconditional when the abrasive loss exceeds allowance.

Title: Cylindrical cell and manufacture thereof
Inventor: IZUMI KATSUTOSHI
IPC: H01M2/02
Filed: 1994-06-21
Abstract: PURPOSE:To increase the circularity of a metallic outer packaging can, increase the capacity of a cell, and concurrently enhance fluid leakage resistance performance by forming an arcuated section the radius of curvature of which is in a range of the specified percentage of the radius of the metallic outer packaging can, in the butted section of the metallic outer packaging can over its cylinder. CONSTITUTION:Arcuated sections 15 are formed, for example, on both side end sections 14 of a tin plate 13 which is as thin as 0.2mm, and tempered to 2.5, and the side end sections 14 are butted against each other so as to be wound into a cylindrical shape in such a manner that each arcuated section is located in the inside of the tin plate 13, so that the tin plate is thereby formed into an outer packaging can 10. In this case, the radius of curvature (r) of each arcuated section 15 is in a range of 20 to 35% of the radius of the metallic outer packaging can 10. If the radius of curvature of the arcuated section 15 is so small as to be less than 20% of the radius R of the metallic outer packaging can 10, the butted section of the outer packaging can is projected inwardly to the inside of the outer packaging can, impairs a tube 8 made of synthetic resin, and degrades its fluid leakage resistance properties. On the other hand, if the radius (r) is so large as to be equal to or more than 35% of the radius R of the outer packaging can 10, it is not preferable because the butted section of the outer packaging can 10 is projected outwardly. Therefore, the radius (r) which is equal to 20 to 35% of the radius R, is preferable because the circularity of the outer packaging can is enhanced.
