Title: Printer
Inventor: TAKANO YUICHI
IPC: H04N1/409
Filed: 1998-07-10
Abstract: PROBLEM TO BE SOLVED: To attain edge enhancement in response to the signal level and the representation capability of the printer by applying emphasis in a positive direction when image data of a center pixel are less than a reference value and applying enhancement in a negative direction when the image data of the center pixel are the reference value or over in the case of conducting edge emphasis based on a difference between the center pixel and a peripheral pixel. SOLUTION: A peripheral pixel detection means 12 obtains the difference ΔD=Da+Db+Dc+Dd-4Dt based on image data Dt of a center pixel being a target pixel, and each of image data Da, Db, Dc, Dd of peripheral pixels at upper/lower/left/right positions of the center pixel. A filter changeover means 13 and a filter means 14 obtain correction image data Dt' as follows: in the case that the image data Dt is less than a reference value A and ΔD<=0, Dt'= Dt-ΔD×k, in the case that the image data Dt is less than the reference value A and ΔD>0, Dt'=Dt, in the case that the image data Dt is the reference value A or over and ΔD>0, Dt'=Dt-ΔD×k, and in the case that the image data Dt is the reference value A or over and ΔD<=0, Dt'=Dt, where k is a filter coefficient.

Title: Sorter
Inventor: MATSUO KAZUHIRO
IPC: B65H39/11
Filed: 1986-08-20
Abstract: PURPOSE:To reduce the difference of sheet transport speed between a sorter and an image forming device by arranging a transport means for transporting and discharging a sheet into an accommodating part and a transport speed selecting means for selecting the sheet transport speed of the above-described transport means. CONSTITUTION:A sorter S is connected with an image forming device M having the speed different from the sheet transport speed of the sorter, and the sheets P discharged from the image forming device are assorted and accumulated into an accommodating part (tray) T'. In this case, during the time when the discharged sheet P is restrained in the image forming device M, the sheet transport speed of the transport roller pairs of the transport means 7a and 7b of the sorter S is switched by a transport switching means 45 so that the sheet transport speed nearly corresponds to the sheet transport speed of the image forming device M. Further, when the discharged sheet P is released from the restraint by the image forming device M, the transport roller pairs of the transport means 7a and 7b of the sorter are switched to restore a prescribed sheet transport speed. Therefore, the difference of the sheet transport speed between the sorter S and the image forming device M becomes zero, and generation of noise can be prevented.

IPC: G02F1/13357
Filed: 1992-06-30
Abstract: PURPOSE:To manufacture a high brightness EL display element of thin film type emitting light with a color other than yellowish orange. CONSTITUTION:A base board 19 is installed at a susceptor 18 provided in a reaction furnace 11 of a MOCVD (organic metal gaseous phase growing) device 100.

Therein the emission center substance 17 in a reaction chamber 15 upstream of the nozzle 14 is conveyed by a reductive gas and introduced to the reaction furnace 11 in reduced state. Therefore, it is possible to form a light emission layer in which the emission center substance is uniformly distributed in the parent material. The resultant thin film type EL display element can be of high brightness and high quality even though it has a light emission layer presenting a color other than yellowish orange due to zinc sulfide: manganese(ZnS:Mn).

Title: Rotary switch
Inventor: SUZUKI TADAAKI
IPC: H01H19/08
Filed: 1989-07-29
Abstract: PURPOSE:To ensure proper contact capability between a common contact piece and a common fixed terminal piece, and obtain compact design by caulking the common contact piece or forming a caulked projection on the common fixed terminal piece. CONSTITUTION:A common contact piece 16 is so constituted as to be caulked with caulking projections 17A and 17B formed on common fixed terminal pieces 10 and 13. As a result, a rigid fixing condition of the contact piece 16 can be obtained concurrently with caulking. In other words, the contact piece 16 is free from such an afloat condition as seen in fusion fixing, and kept in good contact with the common fixed terminal piece 10. In particular, a rotor 5 is in contact with only a plurality of moving contact pieces 18A to 18D projected from the contact piece 16 and, therefore, the rotary condition of the rotor 5 is stable. Also the contact pieces 18A to 18D are free from a possibility of separation due to the motion of the rotor 5 and operational stability can be ensured. Furthermore, the common contact piece 16 does not need a conventional fixing piece in the parallel arrangement direction of the contact pieces 18A to 18D. The outer diameter of a switch in the parallel arrange arrangement direction, therefore, can be made small.

Abstract: PURPOSE:To attain the alternative recording between the video and sound signals on a video track by deciding the presence or absence of the video signal input and switching automatically the reference signal to be supplied to a servo circuit to a signal or its related signal which is synchronous with the synchronizing signal contained in the video signal. CONSTITUTION:The sound signal sent from a sound signal source 1 is applied to an FM modulating circuit 7; while the video signal supplied from a video signal source 2 is applied to a video processing circuit 9 as well as to a separating circuit 10 which separates a synchronizing signal. One of vertical synchronizing signal supplied from the circuit 10 is applied to a deciding circuit 13 and another signal is applied to a transmitting circuit 14. The circuit 13 delivers a decision output only in case the synchronizing signal exists and at the same time a VTR device is set in a record mode. The circuit 14 delivers an oscillation signal which is driven synchronously with the vertical synchronizing signal. An oscillation signal generating circuit 23 always delivers an oscillation signal of 60Hz independently of an oscillation circuit 20. A switch circuit 21 selects the output of the circuit 14 when the decision output given from the circuit exists and then the output of the circuit 23 when said decision output does not exist and supplies the selected output to a servo circuit 26.

Filed: 1994-08-23
Abstract: PURPOSE: To provide an image reader with excellent reliability from which a signal used to surely identify the characteristic of an image being an object to be read such as the change in white/black levels is outputted. CONSTITUTION: A read state to a reference board having two reference colors such as white/black colors is set at first and then a read state to an object 3 to be read is set. When the reference board 7 is read, a black level in an output voltage of a CCD 6 is held. In the case of reading the reference board 7 and the object 3 to be read, the output voltage of the CCD 6 is clamped by a clamp circuit 14 at a hold level and amplified by an AGC circuit 15. In the case of reading the reference board 7, the gain of the AGC circuit 15 is controlled so that the output voltage of the AGC circuit 15 reaches a setting value (corresponding to white level) and the gain is held by reading of the object 3 to be read. Finally the output of the AGC circuit 15 becomes a read signal.
