Title: Medium to be recorded, manufacture thereof, and image forming method using the same
Inventor: OGINO HIROYUKI
IPC: B41M5/52
Filed: 1999-05-21
Abstract: PROBLEM TO BE SOLVED: To keep the natural touch of a base paper and check the surface diffusion of ink so as to heighten the concentration of an image and its resolution and improve the absorbability of the ink by a method wherein an ink accepting layer is formed in island-like shapes sporadically interspersed on the surface of the base paper on at least one side of the base paper mainly made of pulp fibers. SOLUTION: By sporadically interspersing a ink-accepting layer 2 in island- like shapes on the surface 1 of a base paper, the surface diffusion of ink is limited within the interior of each island of the ink accepting layer, resulting in suppressing the surface diffusion of the ink. The shapes of the ink accepting layer 2 are not limited only to squares and can be arbitrary shapes sporadically interspersed in the island-like fashion. Under the state that the ink accepting layers are sporadically interspersed in islands, the average diameter of the ink accepting layers is preferably 3 to 250,μm, more preferably 5 to 100 μm. The covering rate of the ink accepting layers in the base paper is preferably 30 to 70%, more preferably 50 to 70%. The material of the base paper is not specially limited as long as one is mainly made of fibrous pulp.

Title: Human power propelling device for boat rowable in advancing direction
Inventor: OTA OSAMU
IPC: B63B35/73
Filed: 1999-04-13
Abstract: PROBLEM TO BE SOLVED: To safely operate a human power propelling device without causing a danger of colliding with the other ship and an obstacle by dividing a single oar into an operation bar and a paddle part, arranging support bearings, fitting these in a support shaft of the ship side center by joining both support bearings, and advancing a boat in the front direction by using a propelling rope and a pulley. SOLUTION: An object connected by an operation bar 2, a paddle part 3 and support bearings is fitted in a support shaft, a propelling rope 6 is tensioned, and an elastic cord 7 is stuck together. When an operator sits in the bow direction from this state and rows an oar by a conventional method, the paddle part 3 acts in the direction for advancing a ship to advance the ship. After finishing paddling, the oar returns to a former position by tensile force of rubber tensioned in front of a support shaft 1 from a paddle front part. Thus, since a manpower propelling device is operated in the advancing direction, a course can be easily adjusted to prevent a collision with the other ship and an obstacle to safely operate the manpower propelling device.

Title: Optical recording and reproducing device
Inventor: HORIKAWA YOSHIAKI
IPC: G11B11/10
Filed: 1987-06-09
Abstract: PURPOSE:To sharply increase the recording capacity of an information recording medium by arranging a condenser lens for forming a condensing point on a position conjugate with a recording layer in front of a detector and positioning a pin hole on the condensing point. CONSTITUTION:The condenser lens 6 for forming its condensing point on a position conjugate with the recording layer 5b is arranged in front of the detector 8 and the pin hole 7 is positioned on the condensing point to constitute a detecting system as a confocal system. Since the pin hole 7 is arranged on the condensing position of the condenser lens 6 which is a conjugate position with the recording layer 5b, reflected light from recording layers 5a, 5c other than the recording layer 5b is not reached to the detector 8. Thereby, only the information on the recording layer 5b is detected. Even if an interval between the recording layers in the information recording medium is short, no detecting error is generated, so that the recording capacity of the information recording medium can be sharply increased.
