Title: Steering device for vehicle
Inventor: OYAMA YASUHARU
IPC: B62D6/00
Filed: 1998-03-03
Abstract: PROBLEM TO BE SOLVED: To provide a desired steering feeling of individual driver according to travel conditions and steering conditions by providing an adjusting means that manually changes an auxiliary reaction torque value added to an auxiliary steering torque value step-like or continuously over specific steps. SOLUTION: A multi-stage switch 18 as an adjusting means, which manually changes a ratio of an auxiliary steering torque to an auxiliary reaction torque and/or a sum of the auxiliary steering torque and the auxiliary reaction torque step-like over two steps by multiplying a desired coefficient to them, is connected with an auxiliary steering torque determining means 17a and an auxiliary reaction torque determining means 17b. This multi-stage switch 18 selects three positions, for example a city area, a high way, and a winding road, and sets coefficients multiplied to the auxiliary steering torque and the auxiliary reaction torque so as to provide turbulence restraining effect and steering feeling according to each travel road. Thus, drivers can get a desired steering feeling only by selecting a position according to their travel road.

Title: Axial flow fan
Inventor: GOTO KAZUHIRO
IPC: F04D29/32
Filed: 1993-03-11
Abstract: PURPOSE:To provide an axial flow fan for embodying low noise. CONSTITUTION:In an axial flow fan 1 constituted in such way that a plurality of wings 3 on the outer circumference of a hub 2, a plurality of (the same number as the wings 3) fins 5 are installed on a hub cap 4 mounted on the hub 2. Since a negative pressure range generated conventionally to rearward of the hub 2 (the hub cap 4) by boosting action of the fins 5 which rotate together with the hub 2 is eliminated, generation of turning flow in rearward of the hub 2 and the generation of vortex caused by turning flow are suppressed, and noise pressure fluctuation is suppressed so as to reduce noise. And also, in the case where a part of the outer circumference of the wings 3 are overlapped each other at face-seeing, or a cylindrical shroud is installed integratedly on the outer circumference of the wings 3, same effect is obtained.

Title: Synchronizing circuit
Inventor: TAKADA KAZUHIRO
IPC: H04J13/00
Filed: 1984-03-16
Abstract: PURPOSE:To allow a receiver for frequency hopping spectrum spread communication to acquire synchronism securely by providing an FSK demodulator which receives a reverse spread signal and generates a data signal and a synchronism decision circuit which detects the coincidence between the data signal and a predetermined data pattern. CONSTITUTION:A conventional circuit is equipped with the 2nd decision circuit 15 consisting of the FSK demodulator 13 and a counter 14. Synchronism is acquired by using the output of the 1st decision circuit 2, but a control circuit 11 sends a timing signal 105 to the synchronism decision circuit 15 and the rate of ''1'' in the data signal is counted to decide on synchronism after tracking according to whether the counted value attains to a specific value or not. At this time, the value supplied to the counter 14 corresponds to the threshold level supplied to the 1st decision circuit 2, but this value is set according to an error rate of data and finely settable. The result of the 1st decision circuit 2 is determined by a signal-to-noise ratio and hardly influenced by AGC because the FSK demodulator 13 obtains the data signal by comparing a signal level with a noise level relatively.

Abstract: PURPOSE:To set free the angle of a roof to a cross beam. CONSTITUTION:A beam angle adjustable device B is installed between beams 13 which constitute a structural body for cross beams 4 and a roof 12 so as to make adjustable the beam 13 to the cross bar 4, that is, the angle of the roof 12, thereby securing the adaptability of the installation of a weather shed A to an inclined spot in the cross direction of the cross beams. The beam adjustable device B threads a fixing base section 32 of a fixing connector 31 into a connector receiving seat 10 of the cross beams 4 with a screw 34 by using a beam joint 30 by the fixing connector 31 and a rotary base member 37. A projected joint section 41 of the rotary base member 37 is fixed with the beam 13 where a projected wall section 35 of the fixing connector 31 and a rotary base section 38 of the rotary base member 37 are laid out in such a fashion that they may be doubled and fitted into each other. Furthermore, they are shaft-supported so that the rotary base section 38 may be rotated. This construction makes it possible to allow the beam angle adjustable device B to determine the angle of the roof 12 at a desired value freely even when a post 1 is erected vertically on an inclined spot in the direction of the cross beams.

Title: Developing device
Inventor: HIRANO KOJI
IPC: G03G15/08
Filed: 1994-03-22
Abstract: PURPOSE:To decrease the torque between a developing roller and a toner layer forming blade, prevent the deterioration of an image due to the filming of a toner, and provide a good image over a long period by dispersively depositing glass beads having the grain size smaller than the grain size of the toner on the surface of the elastic body layer of a developing roller. CONSTITUTION:A developing roller has a two-layer structure of an elastic body 102b and a surface conducting layer 102c around a carrier 101a made of a metal shaft, and glass beads 102d having the grain size smaller than that of toner grains are dispersively deposited on the surface of the surface conducting layer 102c. The density of the glass beads 102d is 1.1-1.5g/cm<3>, and they are dispersed to have the surface coverage of 20-60&. When the surface coverage becomes higher than 60%, grains are brought into contact with each other, thus causing the situation like the existence of apparently large insulating grains. When the toner on these grains is developed, charges have no escape position, and the subsequent development is adversely affected. When the surface coverage is below 20%, the starting torque is made large.

Title: Manufacture of moire grating
Inventor: IGARI TOSHIHIDE
IPC: G01N3/06
Filed: 1987-03-05
Abstract: PURPOSE:To easily form heat-resisting moire gratings on many test-pieces by arranging a coating plate which has many parallel slits on the test-pieces, projecting laser light and then moving the coating plate, and projecting laser light again. CONSTITUTION:Many parallel slits 22 arrayed at the same pitch with the heat- resisting moire gratings are provided in the surface of a mirror 21 which is the coating plate. Then the mirror 21 having the slits 22 is placed on the plane test-pieces and irradiated with the laser parallel light beam from above. Consequently, only laser light beams passed through the slit parts of the mirror 21 reach the surfaces of the test-pieces to form grooves conforming with the shape of the slits 22. Then the mirror 21 is rotated by, for example, 90 deg. to project the laser light beams repeatedly, thereby forming orthogonal grooves. Consequently, the heat-resisting moire gratings are manufactured in a short period for the many test-pieces.

The top surface thereof positions at A, and the fuel gases and the air are mixed and are ignited to burn, so that the fluidized bed is heated. The fluidized bed is heated gradually from the top surface A side to downward, and is  heated to uniform temp. by the lapse of time. This temp. is kept at 500-580 deg.C, into which articles such as shafts, gears or the like are immersed and are contacted  with the gaseous atmosphere, whereby they are carbo-nitrided.

Title: Photosensitive switch device
Inventor: FUJIOKA ARIO
IPC: G06F3/042
Filed: 1986-03-07
Abstract: PURPOSE:To use a display part also as an operation switch group in common by selectively detecting the light of a weak lighting LED on a matrix array by a photosensitive pen and converting the light into address information to control the display lighting of the LED. CONSTITUTION:The LEDs on the matrix array are weakely lighted by column selecting pulses to be successively repeated, row selecting pulses to be continued three times, or the like. When the photosensitive pen provided with a phototransistor PH1 is set up on a required weakly lighting LED, weak light emission corresponding to the address of the LED is detected and converted into an electric signal. The light emission display of the LED is controlled by using the electric signal as its address. When said operation is similarly executed by applying external light to the phototransistor PH1 without closing a window part of the photosensitive pen by a finger, the corresponding LED is turned off. Thus, the display part can be also used as the operation switch group in common and key operation can be easily and accurately executed.
