Title: Electrically conductive elastic roll for electrifier
Inventor: SOMIYA TOKUMASA
IPC: G03G15/02
Filed: 1997-05-23
Abstract: PROBLEM TO BE SOLVED: To obtain stable potential by electrification without causing image defects at the time of electrification by contact with an image carrier. SOLUTION: The roll part 2 of an electrically conductive elastic roll 1 is composed of a rubber elastic layer 3 having 40-60 deg. JIS.A hardness and a surface layer 4 of a resin having a pencil hardness of >=B formed on the outside of the elastic layer 3. Since the roll part 2 has the somewhat hard rubber elastic layer 3, adhesion to a photoreceptor 8 can be maintained by elastic deformation. The transfer of an additive exuding from the elastic layer 3 to the photoreceptor 8 can be prevented by the surface layer 4 and the transfer of a ccntaminant from the photoreceptor 8 can also be prevented because the surface layer 4 is hard.

Title: Reverberation time measuring instrument
Inventor: YAMAGUCHI OSAMU
IPC: G01H7/00
Filed: 1978-10-31
Abstract: PURPOSE: To prevent an erroneous measurement, an output to be used for alarm is detected in the specific area in a reverberation time measuring circuit.  
     CONSTITUTION: Sound energy from the squarer 5 is processed by the over noise detector 19 and the amplifier saturation circuit 18 having a threshold-set-comparator, a hold circuit, etc. This permits the detection of saturation of the pre-amplifier 2 connected to the microphone 2, and the finding of excessive sound energy due to superimposed noise. The detected results are shown as alarm lightings of the lamps L 18 , L 19 . Similarly the lamps L 20 , L 21  are used to indicate alarms for an over and under sound energy compared to the specified value, through the detectors 20, 21, etc. for over and under integrated outputs. This prevents an erroneous measurement due to a false signal processing and permits a reverberation time measurement with a little error.

Title: Method for evaluating adhesive property between ceramic green sheets
Inventor: HO KEIICHIRO
IPC: B28B11/02
Filed: 1990-05-28
Abstract: PURPOSE:To evaluate adhesive property between ceramic green sheets readily by laminating a plurality of the ceramic green sheets, permeating colored liquid into the cut surface of a sample which is cut from the central part,and computing the area rate of the colored part after polishing. CONSTITUTION:At first, ceramic green sheets are laminated. A laminated body 3 is cut from the laminated body 2. The cut surface is polished surface, and the surface is dried. Each cut surface is observed with a metal microscope. Ink is permeated into the sheet bonding part of the laminated body whose adhesive property is poor, and a line appears clearly. The length of the part is computed based on the photograph. The value obtained by dividing the length by the length of the entire body is made to be the area rate. Then, the better the adhesive property, the smaller the area rate. Thus, the adhesive property between the ceramic green sheets can be readily evaluated, and the possibility of the occurrence of peeling between the layers can be judged.
