Title: Roller and developing device
Inventor: TAKAGAKI HIROMITSU
IPC: G03G15/08
Filed: 1996-10-21
Abstract: PROBLEM TO BE SOLVED: To obtain a roller excellent in elasticity and having various values of volume resistivity by constituting an elastic body of the roller of a high molecular base material which contains resin made spherical bodies encapsulating a low b.p. hydrocarbon. SOLUTION: The elastic body of the roller is composed of the resin-made spherical body-containing elastic body containing resin-made spherical bodies 5 using a high molecular material 4 as the base material and encapsulating a low b.p. hydrocarbon. Since the low b.p. hydrocarbon included in the resin made spherical body 5 is in a gaseous state and functions as bubbles, the resin made spherical body-containing elastic body has excellent elasticity. Thus, by blending carbon in the elastic layer or the like, the elastic layer having various required volume resistivity can be obtained and various rollers of from a low resistivity conductive roller to a high resistivity conductive roller are obtained.

Title: Optical information recording/reproducing method
Inventor: HAYASHI YASUO
IPC: G11B7/085
Filed: 1989-11-18
Abstract: PURPOSE:To shorten time until the recording or reproduction of information is started by starting a focus servo pull-in operation by means of an optical pickup from the detection time of insertion of an optical card into a controller to an initial positioning time. CONSTITUTION:When the optical card 1 is inserted from the insertion port 15 of the controller (state A), an insertion sensor 16 detects the card (state B). The controller drives a motor 17 by the signal, rotates a rubber roller 18 and moves the card 1.

Abstract: PURPOSE:To obtain through an industrial continuous process the subject compound useful as a raw material for methyl methacrylate, by reaction between alpha-hydroxyisobutyramide and methyl formate in the presence of a catalyst prepared efficiently in a continuous multi stage distillation column. CONSTITUTION:The medium stage of a continuous multistage distillation column 1 is charged with alpha-hydroxyisobutyramide via line 4 and an alkali metal hydroxide (esp. pref. NaOH) via line 5. These two kinds of feedstocks are brought into mutual contact to produce a dehydrated condensate, and the water as a by-product is distilled off the system via line 6 through the top of the column, while the dehydrated condensate is supplied through the bottom of the column via line 7 into a reactor 2. Concurrently, methyl formate is fed via line 8 into the reactor where the dehydrated condensate is made to react with the methyl formate to afford the objective methyl alpha-hydroxyisobutyrate. The feed ratio for the alkali metal hydroxide to the alpha-hydroxyisobutyramide is 0.5-10mol%. The bottom temperature of the distillation column 2 is 130-160 deg.C, the degree of vacuum being 5-20Torr. With this method, the dehydrated condensate as catalyst can efficiently be prepared by reaction distillation system; and therefore, the aimed compound can be obtained in high selectivity and advantageously.

Title: Execution control system for patrol diagnosis
Inventor: IWATA ATSUSHI
IPC: G06F11/22
Filed: 1990-11-05
Abstract: PURPOSE:To shorten an execution time by linking a corresponding diagnosis reinforcing program with a reference diagnostic program when the number of generated retrials or error correcting events exceeds a previously determined limit value. CONSTITUTION:A central processing unit (CPU) 3 executes the reference execu tion diagnostic program as a patrol diagnostic program based upon a patrol diagnostic interruption generated in a diagnostic device 4. If a 1-bit error is generated in a memory part of a main storage device 2, the number of corrections is increased and a diagnostic device 4 recognizes the excess of the limit value, the device 4 links a main storage access combination program with the reference execution diagnostic program stored in the main storage memory. Thus, the number of retrial or error corrections in the system is monitored, and when the monitored object exceeds the previously determined limit value, patrol diagnosis is automatically reinforced. Thereby, a patrol diagnostic program reducing time influence upon a user program and having small capacity is executed at normal time.
