Title: Tape cartridge
Inventor: MIZUTANI HIKARI
IPC: G11B23/087
Filed: 1986-03-20
Abstract: PURPOSE:To prevent a gap from being generated in a mating face of the upper and the lower cases, even if the titled tape cartridge is left unattended for many hours under a high temperature atmosphere, by providing a pair of plate- shaped ribs being orthogonal to side walls of the upper and the lower cases. CONSTITUTION:From the inside surfaces of side walls 10a, 10b of the upper and the lower cases 1a, 1b, at least a pair of plate-shaped ribs 12, 11 are projected orthogonally, respectively, and the plate-shaped ribs 12, 12 of the upper case 1a side are made to contact or opposed adjacently to horizontal outside surfaces of the plate-shaped ribs 11, 12 of the lower case 1b side, respectively. Therefore, under a high temperature atmosphere, both the ribs 12, 11 abut on and are engaged to each other, and by a frictional engaging force generated in that case, a deformation of the upper case 1a is suppressed. Accordingly, a large gap is not generated between mating faces 13 of the upper and the lower cases 1a, 1b, an external appearance of a tape cartridge is not deteriorated, a stable run of a tape is not obstructed, and it can be prevented well that dust invades the inside of the case.

Title: Photo matrix switch
Inventor: ASATANI KOUICHI
IPC: G02B26/08
Filed: 1979-05-23
Abstract: PURPOSE:To obtain the photo matrix switch of non-blocking type by disposing the optical path changing elements using reflection on the points of intersections among four fiber arrays. CONSTITUTION:An optical path changing element 10 has the two reflecting faces in which the mutually opposing two faces AB and ED as well as BC and EF become mutually parallel and is formed at smaller than 45 deg. in the angle that it assumes to the optical axis. If the element 10 is disposed at the point of intersections of the lines connecting optical fibers 1-1', 2-2', 3-3', 7-7', 8-8', 9-9', the respectively corresponding optical fibers are connected. If, here, the fibers 2 and 9' are going to be connected, the optical path changing element 102.9 is removed from the point of their intersection, and this causes light to enter from the fiber 2 and be connected to the fiber 9'. At this time, the light incident from the fiber 9 is similarly connected to the fiber 2'. In this way, the photo matrix switch of non-blocking type may be readily obtained simply by removing the element 10 on the corresponding points of intersection.

Title: Mode filter for optical fibers
Inventor: ASATANI KOUICHI
IPC: G02B6/14
Filed: 1978-05-30
Abstract: PURPOSE:To make obtaining and axial alignment of those of required filter characteristics easy and reduce insertion losses by opposing two focusing type rod lenses of different numerical apertures in performing mode selection. CONSTITUTION:If the numerical aperture of a rod lens 7 is made smller than the numerical aperture of a rod lens 8 and light is entered from an optical fiber 5, then lower roder mode is selectively excited in an optical fiber 6 at low loss. Conversely, if light is entered from the optical fiber 6, higher order mode becomes leakage mode and creates a function as a mode filter, coupling only the lower order mode to the fiber 5. Since the rod lenses 7, 8 are made at 1/4 pitch, the image on the butt end face of one rod lens and fiber forms a real image on the butt ene face of the other rod lens and fiber. This reduces the insertion losses of transmission mode. In addition, the use of the focusing type rod lenses enabled the one of required filter characteristics to be obtained with ease and eables axial alignment to be made easy.

Title: Antiskid brake control system
IPC: B60T8/48
Filed: 1992-03-21
Abstract: PURPOSE:To prevent a brake pedal from advancing in and a wheel cylinder from improper pressure reduction by effectively reducing a kickback at the time of antiskid brake control, and also enabling a recirculating amount of brake fluid to increase from a pump when a high pressure is generated in a master cylinder. CONSTITUTION:When a low pressure is generated in a master cylinder l, an opening/closing valve 22 is closed, and brake fluid delivered from a pump 14 passes through a kickback reducing orifice 18 to recirculate by properly limiting a flow amount to the master cylinder 1. When a pressure of the master cylinder 1 is increased to a preset value or more, the opening/closing valve 22 is opened by a detection signal of a pressure sensor 23. As a result, the brake fluid from the pump 14, passing through a bypass passage 21, is recirculated without limiting a flow amount to the master cylinder 1. Accordingly, even when the pressure of the master cylinder 1 is the preset value or more, the brake fluid recirculated from the pump 14 is increased.

Abstract: PURPOSE:To control switching of vibrationproofing effect according to input vibration for a mounting device in which fluid chambers are provided between an internal cylinder and an external cylinder by providing a partition member which communicates with, or shuts off the orifice path whose cross-section/ length ratio is the largest of all. CONSTITUTION:When vibration is input between an inner cylinder fitting 10 and an outer cylinder fitting 12, based on the variation in inner pressure caused between a pressure-receiving chamber 60 and an equilibrium chamber 62, flow of fluid is generated through a first and a second orifice paths 64, 66. According to the input vibration, a partition fitting 86 is driven and controlled so as to communicate or shut off the second orifice path 66. Based on resonance of the fluid flowing in the orifice paths 64, 66, vibrationproofing effect can be efficiently performed. Tuning of the orifice path is done by adjusting a ratio of cross-sectional area and length of the flow paths under the stated condition of a mounting spring characteristic and of viscosity of a sealed fluid, and the larger the ratio of cross-sectional area/length, in the higher frequency region the resonance is generated.
