Title: Concrete segment
Inventor: TOIDA HIROSHI
IPC: E21D11/08
Filed: 1996-08-27
Abstract: PROBLEM TO BE SOLVED: To irregularity-fit segments together without requiring the fasteing by bolts and facilitate assembling by protrusively or recessively arranging rolled angle steels on the outside of the periphery of the concrete segment for a tunnel inner wall. SOLUTION: Rolled angle steels 12S, 13S, 14S, 15S are protrusively or recessively arranged on the outside of the periphery of a concrete segment 10, and they are welded to reinforcing bars 16 and a fixed reinforcing bar 17 to be fixed in concrete 18. When the segments 10 are to be connected, seal materials are inserted between the irregularity-fit rolled angle steels S to improve the water stop property. The rolled angle steels S are connected together subsidiarily by bolts, headed pins, clamps, or clips, and the segment 10 is fixed to the base rock of a tunnel inner wall by lock bolts. The soil pressure from the peripheral natural ground is received by the irregularity-fitting of the rolled angle steels S, no bolt fastening is required, and the segment 10 can be easily positioned via the utilization of the rolled angle steels S.

Title: Recording device
Inventor: NAKAMURA MITSUSATO
IPC: B65H20/00
Filed: 1987-09-29
Abstract: PURPOSE:To reliably inform the end information to a user without increasing the number of parts by recording the end information on the substitute recording sheet when the end of the recording sheet is detected. CONSTITUTION:When the remainder of the recording sheet 4 is decreased and the near end mark is detected by a sheet presence detecting sensor 13a and sent to a CPU, the page being recorded is continuously recorded until it is completed, if the recording for one message has not completed, remaining pages are substitutively recorded on the recording sheet 5. When the substitute recording for one message is completed, the end information that no recording sheet 4 of the A4 size is left is recorded on the recording sheet 5 by a signal from the CPU, and the recording sheet 5 is cut by a cutter 9 and discharged to the outside of this device to inform the information that no recording sheet 4 is left to a user. Accordingly, the end information can be reliably informed without increasing the number of parts.

Title: Method and device two component development
Inventor: KAMIYA TAKAYUKI
IPC: G03G15/09
Filed: 1997-09-08
Abstract: PROBLEM TO BE SOLVED: To secure high density followability even if an image is formed at a high speed or black-white ratio by preliminarily stirring a two-component developer, to charge toner, besides the fact that the charged toner is used for development by using the same two component developer, separating the charged toner band supplying it to the two component developer thereby performing development. SOLUTION: Besides the fact that the charged toner is used for the development by a developing mechanism A, through the use of the two-component developer, the same two-component developer is preliminarily stirred by a preliminary stirring mechanism B to charge the toner, and this toner is separated by a supplying mechanism C, as necessary and supplied to the two-component developer used for the development. In such a case, in the preliminary stirring by the preliminary stirring mechanism B, the toner can be charged to obtain the same charge quantity, on the same electrifying condition as that when the charged toner is used for the development by the developing mechanism A using the two-component developer.  Therefore, the toner charged by this charging is separated by the supplying mechanism C and supplied to the two-component developer differently used for the development by the developing mechanism A, so that even if the charged toner is used for the development as it is, a deficiency in a charge quantity is prevented.

Title: Selection control circuit
Inventor: MUTO HIROSHI
IPC: H03K17/00
Filed: 1987-09-30
Abstract: PURPOSE:To prevent unnecessary initialization operation from being executed by activating a time limiting circuit with a trouble condition signal from a specified circuit to be determined in advance and blocking an initialization signal with the output signal of this time limiting circuit. CONSTITUTION:When the first circuit of a high order priority is troubled, a trouble condition signal 150 goes to be a logical level '0' and since an FF41 outputs '1' and holds this condition, the first circuit is recovered. Then, even when the logical level of the signal 150 goes to be '1', a selection control signal 400 is not changed. Here, the signal 150 is given also to a time limiting circuit 45 and at a trouble generating time, an output signal 450 to be the logical level '1' is outputted only for a T time from the generating time. This signal is inputted to one input terminal of a gate circuit 46 and while the logical level of this signal is '1', an output signal 460 goes to be '1' regardless of the logic of the signal to be inputted to the other input terminal. Accordingly, an initialization signal 350 is blocked by the circuit 46 during the T time from the trouble generating time.

CONSTITUTION:It is inspected that an electrostatic lens 8 be always used in a virtual image region, and when the ratio (V0/V1) of an acceleration voltage (V0) and the extraction voltage (V1) of field emission electron beam, or its reciprocal ratio (V1/V0) is close to a certain range, based on the signal from the controller 19, the level of V0/V1 (or V1/V0) is displayed by a display device 22 through a V0/V1 display circuit 21. Namely, the level range for proper use of V0/V1 is indicated by a green mark in a meter, and its pointer is moved as the V0/V1 is varied, and whether it is in the range for proper use is directly seen by an operator. The improper region of V0/V1 with which an electron beam is hard to control, can be judged appropriately, and a suitable condition of V0/V1 can thus be re-set.
