Title: Sound field controller
Inventor: KOWAKI HIROSHI
IPC: H04S1/00
Filed: 1992-06-25
Abstract: PURPOSE:To increase an expanse sensation in a music assembly hall by a simple constitution by varying a delay time of either stereophonic signal to be branched from an effect sound signal, delayed and generated, a long with time. CONSTITUTION:A stereophonic modulating means 32 consists of an internal RAM or an external RAM of a digital signal processor, and at every sampling period of either signal of digital signals generated by an effect sound generating means 31, data are stored in plural addresses, respectively. Subsequently, by a stereophonic signal modulation control means 33, the data is read out of the stereophonic modulating means 32, as delaying the sampling period. Accordingly, since Rch of the stereophonic signal varies slowly a delay time, a correlation in each time of the left and the right signals due to a fact that the delay time is fixed as before can be lowered. In such a way, an expanse sensation of a stereo of an effect sound can be increased. Also, an expanse sensation of an initial reflected sound and a reverberation sound can be increased.

Title: Charging device, image forming device, and process cartridge attachable to image forming device
Inventor: HIGETA AKIRA
IPC: G03G15/02
Filed: 1992-06-25
Abstract: PURPOSE:To provide a charging device, a process cartridge, and an image forming device wherein radiation noise is prevented by interposing a conductive lubricant between an electrode and a charging member. CONSTITUTION:An electrode 40 makes contact with the end face 31a of the core 31 of a charging roller 30 and has its tip 40a brought into contact with the thrustward end face 31a of the core 31 by the elasticity of the electrode 40 under fixed pressure. Since the tip 40a of the electrode 40 is shaped like V as shown in Figure, there is a slight space around the contact. Grease 50, which is a conductive lubricant, is applied to the space and is always stored therein because of its viscosity; i.e., the space serves as a reservoir of the grease. Electrical conduction of the roller 30 and the electrode 40 is achieved by direct contact as well as by the conductive grease 50 because the grease is continually attached to the electrode 40 and the core 31. Therefore, a discharge does not occur between the electrode 40 and the core 31 and so generation of radiation noise can be avoided.

IPC: H01Q19/10
Filed: 1992-06-04
Abstract: PURPOSE:To recover the transmission reception efficiency of a radio wave by jetting a heated compressed air from a jet nozzle connecting to a pipe at the tip to a horn cover so as to melt snow efficiently. CONSTITUTION:A compressor 20 intakes an external air from a suction port at a lower part of a mount cover 30, compresses the air and sends the compressed air to a nozzle 29 via a coupler 22, a tube 23 and a pipe 25. The air delivered from the jet of the tip of the nozzle 29 is diffused to a prescribed area and jetted to the entire face of the horn cover 6.

That is, the X0 scan signal and the output level of the transistor 7 are processed by the element 8 if a magnetic card is at the part 5. Then the output of this detection is sent to a lateral column line Y0 of the matrix and then fed to an encoder 2. On the other hand, if no magnetic card exists at the part 5, the X1 scan signal and the inverse output of the transistor 7 are processed by the element 10. Then the non-detection output is delivered to the lateral column line Y1 and then fed to the encoder 2.
