Title: Image pickup device
Inventor: OKINO TADASHI
IPC: H04N5/355
Filed: 1991-09-05
Abstract: PURPOSE:To obtain the sufficient quality of a picture by adding-up and averaging the signals of neighboring picture elements in the same condition when the levels of the signals of respective picture elements are less than a prescribed value and setting the signal to be the image signal of the picture elements. CONSTITUTION:The image signals of the respective picture elements are outputted from an image pickup element 2. When the output levels are less than the prescribed value, an arithmetic circuit 8 adds up the image signals of the neighboring picture element in the same condition and averages them. Then, the signal is outputted as the image signal of the picture elements. Consequently, a sufficient image signal can be obtained also to the dark part of an object. When the levels of the image signals of the respective components of respective picture elements outputted from the image pickup element 2 are low, the image signals of the neighboring picture element in the same condition are added up and averaged so that a sufficient image signal of the color can similarly be obtained. Thus, a sufficient quality of the image can be obtained not only to the bright part of the object but also to the dark part of it, the average signal level of the image pickup element can be set low and the dynamic range of the image pickup element 2 can be turned wider.

Filed: 1988-09-09
Abstract: PURPOSE:To unnecessitate a gear for reversing the direction of rotation by forming an idler mechanism whose driving source is a capstan and which attain a required reel driving without reversing the rotational direction of its driving force. CONSTITUTION:When a capstan 46 is rotated in an A direction and a tape 54 is fed forward, a driving belt 50 runs in the A direction and a gear 36 rotates counterclockwise. Consequently, the gear 36 moves on a fixed gear 38A in the A direction, an arm member 30 turns in the A direction with a fulcrum 30A as a center, gears 34 and 44A are engaged to rotate a reel base 44 in a winding direction. Next, when the capstan 46 rotates in a B direction and the tape 54 is fed backward, the gear 36 rotates clockwise and the arm member 30 is rotated in the B direction. Consequently, the gears 34 and 44A are engaged to rotate a reel base 42 in the winding direction. By driving reels without reversing the rotational direction of the driving force like this, the reversing gear is made unnecessary.

Title: Micro injection device
Inventor: KONISHI YOSHIAKI
IPC: A61M5/00
Filed: 1999-08-10
Abstract: PROBLEM TO BE SOLVED: To provide a small and simple-structured injection device preferable as an injection device of insulin in an artificial pancreas, by providing a hydraulic fluid guiding passage for guiding hydraulic fluid in a hydraulic fluid accumulating container into a pump chamber with prohibiting reverse flow and a volume change applying means for changing the volume of a hydraulic fluid storing chamber. SOLUTION: When alternating current is applied to an oscillator-type volume change applying device used for a volume change applying means E, the surface facing to a hydraulic fluid storing chamber A1 vibrates to repeatingly pressurize and depressurize the hydraulic fluid storing chamber A1. When it is depressurized, a delivery-fluid storing chamber A2 is also depressurized via an isolation member B. However, a delivery flow passage A3 is formed with prohibiting reverse flow and thus closed, and hydraulic fluid in a hydraulic fluid accumulating container C is guided into the hydraulic fluid storing chamber A1 through a hydraulic fluid guiding passage D. When it is pressurized, the hydraulic fluid guiding passage D is closed since the reverse flow is prohibited.  Thus, as shown by two-dot chain line, this microinjection device elastically deforms a deflective barrier rib B1 in the delivery-fluid storing chamber A2 direction to deliver the delivery fluid in the delivery-fluid storing chamber A2.

Title: Imaging medium receiving tray
Inventor: HONG JUEHUI PH D
IPC: G03G15/00
Filed: 1997-08-22
Abstract: PROBLEM TO BE SOLVED: To provide a tray for use in printers or other imaging-related devices, capable of controlling the stacked form of imaging medium sheets outputted thereto. SOLUTION: An imaging medium receiving tray has a flat surface 12 and a curved surface 13. The curved surface is designed so as to have series of desired lateral curves 15 and the like and a series of desired longitudinal curves 17, all of which curves are arranged to form a lateral concavity and a longitudinal upward slope. The curved surface accordingly curls the leading edges of imaging medium sheets laterally to give them enough stiffness to permit their stacked state beyond the tip of the tray. The curved surface also prevents stacked medium sheets from rubbing against one another to thus prevent deterioration in quality of their outputted images.

Filed: 1984-10-26
Abstract: PURPOSE:To initialize the memory cells easily and in a short time regardless of the memory capacity by selecting all the addresses of the memory cells of an RAM simultaneously and initialize by writing the same value. CONSTITUTION:When the control signal S is made H, the outputs A1-An of the OR-gate 4 of the row address control circuit become H regardless of the address decode signal a1-an. The outputs of the OR-gate 5 of the column address control circuit also become H. The outputs of the NOR-gate 6 of the write control circuit become L regardless of write data DA. When the write enable signal WE becomes H, L is written in all the memory cells of the RAM, and initialize them in cleared status. The initialization of the RAM in H-level is performed likewise, and eliminates a complicated reset circuit and the likes. Thus the memory cells of the RAM built in the memory device of IC are easily and briefly initialized regardless of the memory capacity.
