Title: Manufacture of printed wiring board
Inventor: SHIBAYAMA KOICHIRO
IPC: B32B15/08
Filed: 1989-07-13
Abstract: PURPOSE:To make it possible to manufacture easily a printed wiring board which is equipped with a specified performance by superposing under pressure and forming a laminated unit in multi-stage mode so that it may not be lapped against a high density region of a circuit pattern of an adjoining laminated unit. CONSTITUTION:A thin material having an internal layer circuit pattern is laminated with a prepreg alternately, thereby forming lamination units 1a, 1b, and 1c. These units 1a, 1b, and 1c are superposed and laid out in multi-stage mode (for example, 10 stages). In this case, these lamination units 1a, 1b, and 1c are superposed in multi-stage mode so that its adjoining lamination units 1a, 1b, and 1c may not be superposed with the position of a power source gland 2a each other. Then, specified pressure application and forming are provided so that a plurality of printed board may be manufactured simultaneously. This construction makes it possible to distribute properly a high density region of the circuit pattern. It is, therefore, possible to distribute the pressure during pressure application and forming totally and hence prevent the generation of burnout in the circuit and short circuit as well.

Title: Image forming device
Inventor: KITAYAMA KUNIHIKO
IPC: G03G15/08
Filed: 1995-07-18
Abstract: PROBLEM TO BE SOLVED: To drastically and totally decrease the probability of the interruption of copying operation by preventing the allowable number of copies from being uniformly set after detecting the residual quantity of toner and increasing the allowable number of copies in accordance with the adhesive quantity of toner. SOLUTION: The toner quantity from a line A (detection surface) to a line B (replenishment feasible surface capable of replenishing a developing device) is about 120g, actually, 100g of toner can be supplied after a toner sensor 74 detects the toner quantity. When the detection is performed by the toner sensor 74 in the midst of consecutive copying, the on-time of the driving clutch 75 of a hopper screw 72 is started to be integrated. Since it takes 200sec to supply 100g of toner in the case the supply ability of the screw 72 is 0.5g/sec, consecutive copying is temporarily interrupted in the case the integrated time attains 200sec before finishing copying.  After the detection, the driving time of the screw is integraed, and the propriety of continuing copying is judged based on the integrated value, so that the allowable number of copies after the detection is prevented from being uniformly decreased, and the toner in a hopper is effectively used.

Title: Data communication equipment
Inventor: KIYOURA SUMIHIRO
IPC: H04L1/16
Filed: 1988-07-20
Abstract: PURPOSE:To prevent lowering in the data transferring efficiency of the title equipment by outputting an end status signal of a state indicating abnormal reception when a received answer signal indicates the abnormal reception and the number of resending times exceeds a set number of resending times. CONSTITUTION:If the value of a counter in a resending control circuit 7 is '0' when a decoded signal SDC indicated abnormal reception, it is discriminated that a preset number of resending times is attained and no resending is performed thereafter. When such state is set, the circuit 7 informs a CPU 1 of the transmission completion of a data block by means of a transmission complete signal SXE and, at the same time, outputs a complete status signal SES which indicates that reception is not made normally to the CPU 1. The CPU 1 can recognize the abnormal reception of the data block from such information. Therefore, the number of resending times can be set arbitrarily and efficient data transfer becomes possible.
