Title: Developing device
Inventor: AKAFUJI MASAHIKO
IPC: G03G15/08
Filed: 1996-03-04
Abstract: PROBLEM TO BE SOLVED: To provide a developing device which steadily supplies developer to a developing roller situated above a developer stirring member. SOLUTION: The developing roller 1 is arranged above the stirring member 10. A developer dash-up member 13 is disposed between and at the sides of the roller and member, and it is rotated and driven. When the front end of the dash-up member 13, made of an elastic material, comes into contact with a projection 14 below, the dash-up member 13 warps by the rotation of its shaft 15. When the shaft 15 further rotates, the contact of the front end of the dash-up member 13 and the projection 14 is released, and it returns to its original shape because of the elasticity of the member. At this time, it violently throws the nearby developer T to the developing roller 1 and steadily supplies the developer to the developing roller 1 together with the magnetic attraction force of a magnetic roll 4.

Title: Diaphragm for speaker
Inventor: KUSAKAWA FUMIO
IPC: H04R7/02
Filed: 1980-04-08
Abstract: PURPOSE:To enable press formation and to increase rigidity by forming a diaphragm for a speaker by using a compound of Mg and C, B and Si. CONSTITUTION:A material for a speaker diaphragm should be less in density (lightweight), large in Young's modulus (large mechanical strength), superior in workability, rigid in shape, and suitable to mass-production. On the other hand, although Al and Ti can be press-formed in outline, Ti is large in density and Al is low in Young's modulus as compared with the density. For this purpose, a compound of Mg and C, B or Si such as MgC2, Mg3B2 and Mg2Si, is used to form the diaphragm. Thus, the thickness can be increased and the workability can also be improved to enable the press work of a complicate shape, so that the diaphragm can be obtained which is large in mechanical strength and suitable to mass-production.

Title: Circuit for reducing electromagnetic interference from magnetic core keyboard
Inventor: KURIFUOODO JIEI BEIDAA
IPC: H03K17/16
Filed: 1987-02-28
Abstract: The present disclosure describes circuit variants for reducing electromagnetic interference from saturable core keyboards to acceptable levels. The invention finds particular application in conjunction with capacitive-discharge scan techniques used in such keyboards. In order to attenuate the external field resulting from such techniques, a circuit is taught which effectively disconnects the scan line array from the capacitor charging circuit during the time between scans. A second variant, when added to the first, further reduces interference by disconnecting the entire scan circuit from the supply potential during the scan time thereby eliminating steady-state currents and turnoff oscillatory transients.

Title: Production of double-layered molded body
Inventor: HIRAIWA YOSHIHIKO
IPC: B29C67/20
Filed: 1990-02-27
Abstract: PURPOSE:To reduce cost and production time by expanding the expandable sheet of a base material layer and thereafter press-molding this base material layer together with a skin layer and an expanded layer between the forming molds and integrating the base material layer to one side face of the expanded layer. CONSTITUTION:An expandable polyolefine sheet 13a is adopted as the raw material of a base material layer 13. The sheet 13a is heated by a heater 22 and expanded to produce the base material layer 13. This base material layer 13 is press-molded between a vacuum pressing top force 23 and a bottom force 21 holding a skin layer 11 and an expanded layer 12. Before press molding, the upper face of the expanded layer 12 is coated with a hot melt adhesive and vacuum press molding is performed in a heating state. The skin layer 11, the expanded layer 12 and the base material layer 13 are integrated to obtain a double-layered molded body 10. Dispersion of thickness of the expanded layer 12 is absorbed by elastic action of the base material layer 13 and unevenness does not occur on the skin layer 11. Since the base material layer 13 itself has cushioning property, the need for both utilization of the cushioning material and a step for integrating this cushioning materials on the base material layer 13 is eliminated. Thereby cost and production time can be reduced.

Title: Memory device
Inventor: USAMI RIYUUICHI
IPC: G06F12/16
Filed: 1981-03-30
Abstract: PURPOSE:To perform the maintenance of a memory device and improve its reliability by generating, holding and informing an error status signal when the value on an output bus is the one other than an expected value at the time other than the output of a data read out from a memory element. CONSTITUTION:When there is no strobing signal STRB1-N at normal operation, all outputs of open collector gates 2-1-1-2-n are ''1''. If the output of any one of the gates 2-1-2-n is fixed on ''0'', the output of a NAND gate 7 is turned to ''1''. Since the output of an AND gate 10 is ''1'' during the non-strobing signal period, a setting signal is generated on the output of the NAND gate 8 by a clock signal and a flip-flip FF11 is set up. Since a strobing signal STRB inputted to an inverter 9 is synchronized with signals STRB1-STRBN, the FF11 is set up and an error status signal is held and sent to a processor.

Title: Secam signal discriminating circuit
Inventor: YAMAMOTO AKIHIRO
IPC: H04N9/47
Filed: 1982-03-26
Abstract: PURPOSE:To prevent malfunction of an SECAM discriminating circuit and to attain stable discriminating performance, even at a weak electric field, by obtaining a burst gate pulse to select a burst signal from a horizontal synchronizing signal gating noise. CONSTITUTION:Only the horizontal synchronizing signal of an inputted composite synchronizing signal is gated at a gate circuit 9, delayed at a delay circuit 2 to be a burst gate pulse. The pulse is inputted to a burst gate circuit 3, where the pulse is gated for the burst period only of the inputted color signal from a terminal 4 and the burst signal is outputted. The frequency is band-converted into DC for a PAL system burst signal, into about 30kHz for an R-Y signal component and about 180kHz for a B-Y signal in the SECAM signal burst signal. In selecting the center frequency of the 1st frequency selecting circuit 12 to 180kHz, a large and a small signal at each 1H are obtained at the output. In detecting this output at a detection circuit 6, a signal including fH/2(about 7.8kHz) component is obtained. Thus, the center frequency of the 2nd frequency selecting circuit 7 is selected to fH/2 and amplified, this is rectified at a rectifier circuit 8 and makes discrimination as the SECAM signal.
