Title: Fluorescent display
Inventor: ONUMA TERUO
IPC: G09F13/04
Filed: 1999-02-10
Abstract: PROBLEM TO BE SOLVED: To make display patterns invisible from a viewing person in front of a display but make the display patterns visible only from the person viewing the patterns diagonally from the display by holding a specified distance between a fluorescent sheet and a surface light source without tight contact with each other. SOLUTION: The front surface of the fluorescent sheet 2 is provided with an optically discontinuous surface forming an image forming section 4. The fluorescent material in the fluorescent sheet 2 is excited by the light cast from the surface light source 3 on the rear surface of the fluorescent sheet 2 and the light of the generated secondary emitted light is emitted beyond the critical angle from the front surface of the fluorescent sheet 2, by which the display patterns are formed. The frame portion of the surface light source 3 is provided with a spacer 5 and the fluorescent sheet 2 is laminated in order to interpose at least an air layer without the tight contact between the fluorescent sheet 2 and the surface light source 3.  The distance is preferably in a range of 1 to 200 mm for practicability although the range depends upon the size of the display patterns of the image display section 4 and the thickness of the fluorescent sheet 2.

Title: Magnetic disk medium
Inventor: MAKINO KIYOSHI
IPC: G11B5/64
Filed: 1995-02-22
Abstract: PURPOSE: To obtain a magnetic disk having excellent durability by providing this disk with a lubricating layer varying in the ratio of the excess component and fixed component of a lubricant in a data area and a CSS area. CONSTITUTION: An Ni-P plating layer 2, a magnetic layer 3 and a protective layer 4 are formed on an Al substrate 1 and the lubricating layer 5 is formed on the surface of the disk. The lubricating layer 5 varies in the ratio of the fixed layer 5a and the excess layer 5b in the CSS area 6 and the data area 7. The lubricating layer 6 is formed over the entire part of the magnetic disk formed with the protective layer 4 by using a lubricant having the low ratio of functional groups and thereafter, the lubricant of the data area 7 is removed by a solvent and the lubricating layer 5 having the high ratio of the functional groups is again formed. Even if a magnetic head floated by such formation moves in the data area 7, there is no transfer of the lubricant and, therefore, even if CSS is executed in this state, the attraction of the magnetic head does not arise.  The sufficient traveling durability is assured by the film thickness of the lubricating layer 6 in spite of the intermittent contact of the magnetic head and the magnetic disk of the data area by the collapse of the balance of the magnetic head by disturbance or infiltrating dust, etc.

Title: Gas proportional controller
Inventor: NAGANO OSAMU
IPC: F23K5/00
Filed: 1997-02-18
Abstract: PROBLEM TO BE SOLVED: To prevent fading of a gas burner as caused by a drop in the degree of combustion during the minimum combustion period by bending a receiving metal for supporting a diaphragm keeping a balance between the atmospheric air pressure and a gas primary pressure in shape along the diaphragm. SOLUTION: The diameter of a valve seat 11 is represented by Dv and the effective diameter of a diaphragm Dp. As a pressure is reduced, the diaphragm 6 is pulled downward and a valve body 5 is pulled upward at the part of the area contacting the valve seat 11. A receiving metal 20 is bent in shape 6b along the diaphragm 6 minimizing the deformation of the diaphragm. The effective diameter Dp subject to the reduced pressure in the deformed diaphragm 6 becomes larger than that of the receiving metal 20 and hence, the area of the diaphragm is larger than the area of the valve seat 11. As the valve body 5 moves downward, the upper swelling 6a of the diaphragm 6 is reduced in deformation to increase the effective diameter Dp.  This allows the separation of the valve body 5 from the valve seat 11 to develop a clearance and atmospheric air enters into a gas path 14 from the downstream side of a protruded part 5a of the valve body 5 thereby eliminating the reduced pressure as mentioned above.

Title: Heat-type intake-air-quantity sensor
Inventor: MATSUOKA HIROKI
IPC: G01P5/12
Filed: 1990-02-16
Abstract: PURPOSE:To operate regulation quickly and accurately by eliminating the effect of acceleration and deceleration for computing the regulation. CONSTITUTION:A bridge circuit 10 is composed of a temperature detecting resistor 12, a heating resistor 14 and adjusting resistors R1, R2 and R3. The resistance value of the detecting resistor 12 is changed in response to the quantity of intake air flowing through an air intake pipe 16. Meanwhile, a voltage which is applied on the heating resistor 14 is controlled so that the temperature is higher than the temperature of the detecting resistor 12 by a specified temperature with a current control circuit 20. The time required for increasing the temperature of the resistor 14 so that it is higher than the temperature of the resistor 12 by a specified temperature is measured with a microcomputer 40. Thus the regulation and the quantity of intake air are computed. In this way, the integrated value of the absolute values of the differences of the neighboring measured values in the computing period of average values and the error factors due to pulsation are computed. The accurate value of the error can be found without the effect of the change in measured value due to acceleration and deceleration. The response in transit driving in acceleration and deceleration is improved.

Title: Call signal detection system
Inventor: ISHIKAWA YUUJI
IPC: H04M11/00
Filed: 1983-03-03
Abstract: PURPOSE:To lead out a call signal of low frequency and a nonringing call signal inputted from telephone circuits through the same transformer and to output them selectively through detecting circuits for those signals which are connected to the secondary sides of the transformers. CONSTITUTION:When a 16Hz signal as a call signal are inputted from telephone circuits L1 and L2, a transistor (TR) 9 turns on and a detection output A goes down to a low level to detect the arrival of the 16Hz signal. At this time, a PLL circuit for detecting a 1,300Hz signal does not operate. When the 1,300Hz signal as the nonringing call signal is inputted, on the other hand, it is amplified by an operational amplifier 7 and then inputted to a PLL circuit chip 8; when its frequency is within a specific band, the detection signal is outputted from an output terminal B by capacitors C2 and C3. At this time, the level of the 1,300Hz signal is sufficiently low, so the TR 9 never turns on.
