Patent JP-H0826274-A (JP)
Title: Easy-to-open lid
Inventor: SHIMIZU TAKASHI
IPC: B65D17/32
Filed: 1994-07-07
Abstract: PURPOSE:To prevent incomplete opening from occurring by making a neck of a rivet wherein a front end is a first arc having a radius of curvature relatively small and a rear half is a second arc having a radius of curvature larger than that of the first arc while a center of curvature of the second arc aligns with a center of a panel. CONSTITUTION:An approximately rear half 15a2 of a neck 15a of a rivet 15 comprises a second arc having a radius of curvature larger than that of a first arc 20. Therefore, a recess is less likely to occur on the rear half 15a2 of the neck 15a. A front end 15a1 of the neck 15a of the rivet 15 comprises a first arc 20 having a relatively small radius curvature. Therefore, since a close arc part 14b along the neck front end 15a1 of a score line 14 has a small radius of curvature, it can be easily cut initially. Since a center of curvature O of the second arc occupying a most part of the neck 15a of the rivet 15 aligns with a center of a panel 11, positioning at the time of fixing the rivet 15 and a picking tab 17 is easy.

Title: Optical recording medium
Inventor: NAKAMURA NAOMASA
IPC: G11B7/258
Filed: 1986-07-30
Abstract: PURPOSE:To obtain an optical recording medium which maintains the recording state stable for a long period of time and has good recording sensitivity at the time of reproducing by laminating a recording layer formed on a prescribed electron compd. having 300-800 deg.C m.p. and metallic reflective layer on a substrate. CONSTITUTION:The thin film of the electron compd. such as MgTl, LiPb, CuGa2, Cu5Cd8, MgHg or AuZn having 300-800 deg.C m.p. is sputtered on the transparent substrate 3 consisting of an acrylic resin or glass to form the recording layer 5. The thin film of Cu, Au or Al is then sputtered to form the reflective layer 7, on which the protective layer 9 is superposed. The electron compd. is formed to the desired state of either one of the non-equil. phase or equil. phase which is different in double refractive index when a laser beam is projected to such recording layer 5 by selecting conditions. The non-equil. phase part is stable at a room temp. and permits recording and erasing for a long period of time. The light B reflected from the layer 7 and the light A reflected from the boundary of the substrate 3 among the laser beams L make multiple reflections at the time of information reproducing. The reflectivity change of the equil. phase part and the non-equil. phase increases as well. The recording sensitivity is thus improved.

Title: Measuring instrument for fine flow rate
Inventor: NOZAKI KAZUO
IPC: G01F1/20
Filed: 1984-08-29
Abstract: PURPOSE:To measure a flow rate as the detected and integrated value liquid drops by providing a dripping means which drip liquid to a constant liquid with a constant droplet amount at wide-range dripping time intervals and a detecting means which detects droplets. CONSTITUTION:A lead-out means 22 is a sideway lead-out mechanism 22b which has an L-shaped hole 26 bored in a recessed part 23 provided to a lower lid part 18, has the opening part of the hole 26 beside the lower lid part 18, and has a desired thin pipe 27 inserted fixedly to lead out liquid sideway. Droplets are led out as a continuous or discontinuous flow depending upon the diameter of the thin pipe 27. When the liquid flaws down along the inner periphery of a droplet pipe 1a, the outflow velocity is reduced through a trumpet type spraed part 29 which expands toward an outer peripheral opening part and the liquid reaches the outer peripheral opening part stably, so that invariably constant surface tension operates. Consequently, the liquid P is dripped at a constant fine flow rate over a wide flow rate range. Then, droplets P are counted by a detecting means 2, whose counted value is multiplied by the fine constant flow rate of droplets P to easily calculate the flow rate.

Title: Optical disk memory
Inventor: YUASA FUMIHIKO
IPC: G11B7/24047
Filed: 1990-07-06
Abstract: PURPOSE:To record information by a multistage form in the inside of a base itself by recording the information by changing the transmittivity of the part of the base to be irradiated by laser light by irradiating the prescribed part of the optical disk base by the laser light, and simultaneously, changing the focus of the irradiation laser light in the thickness direction of the base. CONSTITUTION:A transmission type optical disk system is constituted by using material which is basically transparent and whose transmittivity falls at only the part irradiated with the laser light as the material of the base to be used concurrently as a recording medium. Then, since a very fine white cloudy point corresponding to the spot size of the laser light can be caused at the part of the base irradiated with the laser light by selecting properly the material of the base, the focus of the laser light is changed at intervals of about 10mum in the thickness direction of the base. Thus, multiplex high density recording can be realized without causing crosstalk between layers.
