Title: Developing device of electrophotographic copying machine
Inventor: OOHASHI YASUSHI
IPC: G03G15/06
Filed: 1981-04-24
Abstract: PURPOSE:To perform reproductions in high density and to prevent leakage of bias electric current, by using a magnetic brush sleeve and semiconductive carriers or the like which adhere to the sleeve and have nonlinear electric power- current properties. CONSTITUTION:A developing device is constituted of a magnetic brush sleeve 2, semiconductive carriers 8 which adhere to the sleeve 2 and have nonlinear electric power-current properties and electric sources 4, 5 applying AC electric power superposed in DC to the sleeve 2. When an electric field is inverted before the charged carriers arrive to a photorecepter, the carriers move to the opposite direction toward the sleeve. The density of carriers adhering to the sleeve is increased by inverting the electric field to AC. By such a way, reproductions in high density are performed and leakage of bias electric current is prevented.

Title: Equipment controller
Inventor: KUNII YASUO
IPC: F24D17/00
Filed: 1993-03-22
Abstract: PURPOSE:To prevent the loss of stored working data by connecting a non- volatile storage means and an external storage means and further connecting a control means to be exchanged for this. CONSTITUTION:When a control unit 1 operates a hot water supply bath device 2 and a control means 3 controlling the working of the device 2, a nonvolatile storage means EEPROM 4 storing the learned working history which is necessary for the filling of hot water is connected with an external power source 5. At this point, the ROM 5 is capable of performing an electric writing deletion and a power supply circuit 6 supplies power supply to the control means 3 and the ROM 4. Further, when a connection terminal 8 connecting an external storage means 7 performing the delivery and reception of information with the ROM 4 and the means 7 are connected, a switch circuit 9 switches the connection of the ROM 4 from the control means 3 to the storage means 7. The same data as the working history is made to be stored in the ROM 4. Thus, data is not deleted even when the ROM 4 is non-volatile and a power failure, etc., occurs, and the loss of writing and working data is eliminated in the ROM of the control means at the time of the restart of the unit 1.

Abstract: PROBLEM TO BE SOLVED: To provide an air flow control device in which a variation in a degree of cleanliness caused by an external variation is easily restricted and a high reliability in operation can be attained. SOLUTION: When a direction of air stream detected by an air direction sensor SD arranged at an interface between adjoining area A and area B of a clean room is in a direction (B → A) which is opposite to a predetermined direction (A → B), an amount of clean air supplied from a blower 1 arranged at an area (area A) located at a downstream side is increased and a direction of air stream is controlled to the setting direction (A → B). In addition, as the air direction is corrected from its set direction in an opposite direction, the increased amount of clean air is reduced and then the amount of air is returned back to its original state.

Title: Receiver and received call notice method for receiver
Inventor: SHIINA YASUHIKO
IPC: H04W68/00
Filed: 1995-02-24
Abstract: PURPOSE: To prevent trouble from given to surrounding persons by inhibiting a notice operation even when a call signal is received after a calling notice is conducted continuously for a prescribed time so as to avoid useless notice. CONSTITUTION: When a notice operation by a speaker 10 and an LED 13 caused at the reception of a call signal is not stopped by the operation of a reset key of a key entry section 7 but continues for a prescribed time, the D/D mode is automatically transited and the notice operation afterward is inhibited. Thus, when the user is resident at a remote location, no useless notice is made to prevent consumption of the battery and trouble given onto surrounding persons by sound output from the speaker 10 is avoided. The transition to the D/D mode is informed by indicating the fact by a display section 16. In the case of the D/D mode, the mode is released through the operation of the reset key and the indication of the display section 16 is erased.  Furthermore, since a notice tone different from the usual call reception state is sounded for picture period in the call reception in the D/D mode, the user recognizes the transition to the D/D mode.

Filed: 1985-03-27
Abstract: PURPOSE:To reduce the charge density in an insulating film, by introducing P or As from the surface of an Si3N4 film formed on the insulating film into the insulating film, and performing annealing. CONSTITUTION:On the surface of an Si substrate 21, a source 22, a drain 24 and an offset gate resistance layer 23 are formed. Then, the substrate 21 is oxidized, and a gate oxide film 25 is formed. A polycrystalline Si gate electrode 26 is formed thereon. An insulating oxide film 27 is deposited on the entire surface, and heat treatment is performed. Then, an Si3N4 film 28 is deposited on the film 27. Under this state, P ions are implanted and annealing is carried out. Thus, a high concentration impurity layer 29 is formed. The layer 29 can make the movable ions such as Na and heavy metal, which are present in the film 27, immobile. The charge density in the film 27 can be reduced extremely. As a result, dispersion in characteristics of a threshold voltage is reduced.

Abstract: PURPOSE:To prevent stereoscopic feeling from being damaged by arranging a pair of main speaker on right and left sides in a forward part in a vehicle and arranging plural center speakers near the center of a pair of the main speakers with being respectively directed to a driver seat and an assistant seat. CONSTITUTION:In a driver seat 1, since distances from the driver seat 1 to both right and left channels speakers 4 and 3 are widely different, a sound image is made normal in a position biased to the right speaker 4. However, the lowering of a level in a left channel signal reproducing tone is compensated by reproducing a left channel signal by a center speaker 6 for driver seat. Thus, the sound image biased to a right side can be made normal to the front. Next, in the assistant seat 2, oppositely to the operation as mentioned above, the lowering of the level in a right channel signal l reproducing tone is compensated by reproducing a right channel signal by a center speaker 5 for assistant seat. Thus, the sound image biased to the left side can be made normal to the front.

Abstract: PURPOSE:To contrive an increase in the performance of a magnetic shielding device and a lightening of the device by a method wherein a bidirectional electromagnetic mesh plate or a bidirectional electromagnetic mesh strip is arranged on the joint part of a magnetic shielding material as an object material. CONSTITUTION:A shielding room is assembled using two unidirectional electromagnetic steel plates. A joint 5 of this shielding panel 1 is subjected to a shielding treatment with an object plate 2, which is a bidirectional electromagnetic steel plate. In such a way, if the directional electromagnetic steel plates are used as shielding plates or the object plate for the joint of the panel, it becomes possible to shield effectively leakage magnetic fields in two directions parallel and vertical to the end of the panel 1 without considering the direction and intensity of a leakage magnetic field in the joint part. Moreover, if the bidirectional electromagnetic steel plate, which is used as the object plate, is used as a mesh strip, the execution of the assembly of the panel 1 also becomes more effective also from the viewpoint of shielding performance because the number of joints is reduced.
