Title: Apparatus for detecting residual amount of ink in ink jet printer
Inventor: YAMAZAKI HIROSHI
IPC: B41J2/175
Filed: 1985-07-17
Abstract: PURPOSE:To enable to detect that ink will be empty before long, by providing ink and a separate liquid separated from said ink in an ink chamber and detecting the movement of the separate liquid generated when the residual amount of ink is reduced. CONSTITUTION:A large capacity chamber 27 has an outflow port at a high position in a head direction and receives a liquid 30 having specific gravity higher than that of ink 29 so that the liquid 30 does not flow out ahead of the ink. As mentioned above, the ink and the inert liquid 30 not imparting any action to said ink are simultaneously sealed in one ink bag. Said inert liquid is sucked by negative pressure accompanied by the emission of the ink after the residual amount of the ink is exhausted and detected before sent to a head 21. This detection is performed at a part above an ink cartridge. For example, a membrane like enlarged flow passage part 25 is provided to the upper surface of the outer frame of the cartridge and the color change of the ink is discriminated from said flow passage part. A reflective plate 26 is provided to the bottom surface of said enlarged flow passage part 25 and the detection sensitivity of the reflective type photosensor 33 provided to the upper lid 37 of a printer is enhanced.

Title: Noncontact power transmitter
Inventor: TAKAHASHI MINORU
IPC: H02J7/00
Filed: 1996-06-19
Abstract: PROBLEM TO BE SOLVED: To perform the accurate charge control of a secondary battery, especially, an Li-ion secondary battery, by controlling the output of a power sending coil by the feed back signal being made by converting the optical signal received by a light receiving element into an electric signal. SOLUTION: The optical signal from a light emitting diode 37 is optically transmitted in noncontact to the phototransistor 38 of a charger 8, and is received by a phototransistor 38. Then, it is converted into an electric signal, and is sent to an OR circuit 44 as a feedback signal. The OR circuit 44 sends the logical sum output between the feedback signal and the signal from a starting circuit 43 to a DC/DC converter 41, and the DC/DC converter 41 comes to output voltage (V01 ) by the pulse width control. When the density exceeds 0.8, the heat insulation property or cushion property becomes insufficient, and the objective sensitiveness and picture quality can not be obtained.

Title: Perforating punch
Inventor: MORI CHUZO
IPC: B26F1/32
Filed: 1993-06-03
Abstract: PURPOSE:To reduce the size of a multi-hole perforating punch and to perforate a number of stacked sheets. CONSTITUTION:A plurality of punch blocks 11 into which the number of punch holes of a perforating punch is divided are fixed to a base board 10. An arm 12 to depress punches inserted in punch insertion holes 111 of each punch block 11 is provided.
