Title: Rotary shock absorber
Inventor: YAMAMOTO MASAJI
IPC: F16F9/12
Filed: 1991-08-09
Abstract: PURPOSE:To promote the generation of damping force with viscous resistance by supporting a turning shaft in a cylindrical housing through a bearing, installing a rotor in this tuning shaft, while forming each clearance in both axial and radial directions in an interval between the housing and the turning shaft and filling up viscous oil in this clearance. CONSTITUTION:A turning shaft 2 is supported in a housing 1 through a bearing free of rotation, and a rotor 3 is set up in this turning shaft 2 as in solid rotation. This rotor 3 is made up into a cylindrical form concentrically with the turning shaft 2, and plural units of rotors 3 different in each diameter are arrayed multistepwise in the radial direction at regular intervals. A ringlike projecting piece 4 projected out of the housing 1 is inserted into the interval, thus the rotor 3 and this projecting piece 4 are alternately set up. In succession, both axial and radial clearances 5, 6 are formed in each space between the housing 4, the projecting piece 4 and the rotor 3, and viscous oil is filled up in these clearances 5, 6 and sealed up, and then this viscous oil is made to flow in a hole 7 installed between the rotors. When the rotors 3 are rotated together with the turning shaft as one body, the viscous oil is shifted by a flow velocity conformed to a speed difference in these clearances 5, 6 by means of relative rotation, thus frictional force is produced, turning to a damping force.

Title: Guide rail for lining machine
Inventor: TANAKA KENZO
IPC: A63C19/08
Filed: 1997-08-20
Abstract: PROBLEM TO BE SOLVED: To draw a correct line by forming projections projecting at the ground side of the support body of a guide rail which is constituted of the guide of wheels in a lining machine and of the support body for fixing the guide in a sports stadium. SOLUTION: The guide rail is constituted of the guide 1 for travelling of the wheels of the lining machine and the support body 2 such as a base plate, etc., for fixing the guide and the support body 2 is provided with the downward projections 3. The projections 3 are formed by bending the both end parts of the support body 2 to be in a curved surface shape in a contact direction with lawn. The projections 3 can be the ones which are intermittently formed in the length direction of the rail but they are favorable to be continuously formed. Besides, it is preferable that more than two projections 3 are formed concerning a stability for preventing the rail from being easily inclined at the time of considering the cross section of the rail. Thus, the line is drawn by the lining machine without generating the position deviation of the line.

Title: Surface luminescent device, mold for molding light guide plate and its manufacture
Inventor: FUKUSHIMA YUTAKA
IPC: B29C33/38
Filed: 1999-08-06
Abstract: PROBLEM TO BE SOLVED: To efficiently utilize light incoming in a light guide plate from a line light source by installing the assembly of many non-mirror projections on the surface or the back of a light guide plate, and varying the area ratio of the bottom of the non-mirror projections according to the distance from the end on the line light source side. SOLUTION: The area ratio of the bottom of non-mirror projections 4 is varied so as to increase with distance from a line light source 2. In a part where the area ratio of the bottom is small, most lights emitted from the line light source 2 repeat total reflection inside a light guide plate 1 and are sequentially guided into the innermost part of the light guide plate 1. The rest of the lights emitted is scattered in the non-mirror projections 4, directly emitted from the surface of the light guide plate 1, or passes through the non-mirror projections 4, reaches a back reflecting surface 3 on the back of the light guide plate 1, is reflected here, and emitted from the surface of the light guide plate l. In a part of large the area ratio of the bottom, total reflection is rarely caused, and the amount of light emitted from the surface of the light guide plate 1 is balanced as a whole.

Title: Detection of degradation of linear motor coil
Inventor: NUMAJIRI FUMIYA
IPC: G01R31/06
Filed: 1989-08-30
Abstract: PURPOSE:To enable diagnosis of coil itself by a method wherein I/O terminals are inserted collectively into a penetration type CT in order to cancel the effect of current flowing through the coil and then only the pulsating or vibrating current, flowing to the ground side, is detected for diagnostic purpose of the insulation of the coil. CONSTITUTION:Since current flows through the coil conductor 2 of a linear motor coil 1 in reverse direction at the inlet and the outlet thereof, they are cancelled when I/O terminals 4, 5 are inserted collectively into a CT 6. On the contrary, corona current 10 flows from the side of the shield layer 8 of a joint cable to the joint cable conductor 7 and the coil conductor 2 in same direction at the right and left sides thus being detected through the CT 6. The CT 6 is connected with a filter circuit 14 and a circuit 15 for detecting the corona current 10. Since a large current having frequency component similar to that of the current flowing through the coil 1 flow to the ground side upon dielectric breakdown of the coil 1, it can be detected easily and can be discriminated from the corona current 10.

Patent JP-S6282361-A (JP)
Title: Rotary sensor
Inventor: KUME MASAHIRO
IPC: G01P3/487
Filed: 1985-10-07
Abstract: PURPOSE:To detect a rotating speed by one rotary sensor over a wide range when the rotation of a gear changes from a slow speed to a high speed by providing an intermediate terminal to a voltage generating coil part and applying its terminal voltage and a coil terminal part voltage to a waveform shaping circuit. CONSTITUTION:The coil for voltage generation has a terminal (b) provided nearly at its intermediate part and its terminal part voltage and the voltage of the coil terminal part (a) are inputted to the waveform shaping circuit part 18 respectively. The voltage threshold value VH at the coil output terminal determines whether or not a pulse can be outputted to terminal points (c) and (d) of a voltage comparing circuit part 20. When the gear rotates at the low speed, an output voltage Va rises with the rotating speed N at a point (a) and Va>=VH1 when N>=N1, obtaining a pulse at the point (c). On the other hand, when the gear rotates at the high speed, the voltage Va drops and Va<VH3 when N>N3, so that the pulse at the point (c) disappears. Further, the output voltage Vb at a point (b) becomes Vb>=VH2 for the first time when N>=N2, so that a pulse is outputted to the point (d). Further, when the rotating speed is high, the pulse at the point (d) disappears. Fur the purpose, the pulses at the points (c) and (d) are ORed by an OR circuit part 21 to detect the rotating speed over a wide range from the low speed to the high speed.

Title: Control of cultivation of microorganism
Inventor: KATO KENJI
IPC: C12R1/19
Filed: 1984-10-26
Abstract: PURPOSE:To carry out the control of culture of aerobic microorganism in a manner to achieve high microbial cell concentration without lowering the activity of the microorganism, by controlling the dissolved oxygen concentration within a specific range, and adding a proper amount of medium when the concentration is increased above a preset level. CONSTITUTION:The dissolved oxygen concentration (DO concentration) in the culture liquid is measured (6), and the measured data is inputted through the dissolved oxygen meter 7 and the I/O board 12 to the computer 13. The signal transmitted to the stirrer 4 and the exhaust gas control valve 14 is varied according to the inputted data. The number of revolution of the stirrer 5, the aeration rate, and the pressure in the culture tank 1 are adjusted, and the DO concentration in the culture liquid is controlled within a specific range by this process. When the DO concentration in the culture liquid is increased beyond the preset range despite of the above controlling efforts, the computer 13 judges that the nutrient source in the medium has been consumed, and a signal is transmitted to the medium pump 3 to transfer a definite amount of medium from the medium tank to the culture tank 1 to maintain the proliferation activity of the microbial cells.

Title: Detecting method of leak of seawater
Inventor: YUHARA TETSUO
IPC: G01M3/04
Filed: 1991-09-04
Abstract: PURPOSE:To correctly detect the leakage of seawater without erroneous operation by a method whereby the seawater circulating inside a thermal power plant or the like is sampled, and the concentration of each component such an Na contained in the seawater is continuously monitored. CONSTITUTION:An exciting laser light is guided to a color laser by a beam splitter 4. A turning mirror 9 of the dye laser continuously changes the wavelength of the dye laser by an automatic rotary stage 10. Laser beams of two kinds of wavelengths are introduced to a frame 18 in the same optical axis by dichroic mirrors 16, 17. The generated fluorescence is converted to electric signals by a photomultiplier 22. An interference filter 23 which distinguishes fluorescences of Na and Mg synchronously rotates with the laser, and inputs the fluorescences separately to the photomultiplier 22. The electric signal from the photomultiplier 22 is amplified by a preamplifier 24 and input to a dividing circuit 25. The circuit 25 detects the ratio of the Na and Mg fluorescence signals, thereby to distinguish the increase of Na due to the contamination inside the system and that consequent to the leakage of the seawater.

Title: Ink jet recorder
Inventor: INOUE TOYOFUMI
IPC: B41J2/17
Filed: 1986-09-25
Abstract: PURPOSE:To prevent instability of a jet direction and nozzle clogging by attachment of ink dregs to nozzles and subsequent occurrence of corrosion by forming the nozzles with graphite. CONSTITUTION:Nozzles and an ink recovery part are formed out of graphite. This graphite should preferably be fluoridized on the surface. For instance, in the case of an ink on-demand type, a pressure wave is generated by conversion of an electric signal when it is applied to a piezoelectric element 1. This pressure wave ejects ink supplied to a liquid droplet forming part through the nozzles 3. At that time, since the nozzles are formed out of graphite, they are less susceptible of corrosion and do not allow ink leak easily. Consequently, no ink settlement in the nozzles or their corrosion occurs and also the same things happen to the ink recovery part.
