Title: Rotation detecting structure of vehicle
Inventor: KUMAZAWA TOSHIJI
IPC: B60K17/06
Filed: 1984-07-13
Abstract: PURPOSE:To enable the display of normal speed and running range on a running regardless of the diameter of a tire to be replaces, by providing a gear for detection of rotation detachably on a speed meter mounted on end of a rotating shaft at the final stage of a transmission gear through a wire. CONSTITUTION:Power changed with a main transmission gear 5m and a subtransmission gear 5s is transmitted to a rotating shaft 16 on the downstream side thereof and then to a rear wheel via a coupling 19 and a propelling shaft 20 from a middle shaft 18 through bevel gears 17 and 17. A rotation detector section 8 is provided on the end of a shaft 16 estended from a through hole 21a of a case 21 to detect the rotation proportional to the rotation of a rear wheel from the rotation of the shaft 16. A pair of meshed gears 23 and 24 for detection of rotation are housed in a cover 22 while the cover 22 is mounted detachably on the outside of the case 21. Thus, the gears 23 and 24 as housed in the cover 22 can be separated with the removal of the cover 22 from the case 21. Even when a tire is replaced by the one of a different diameter, the gears 23 and 24 are exchanged for those with the transmission ratio corresponding to the diameter of the tire thereby enabling the inputting of normal rotation into a speed meter.

Filed: 1990-06-04
Abstract: PURPOSE:To enable getting detection information of desired slicing thickness by taking out signal from one or a plurality of split electrode boards which are selected from a signal electrode board. CONSTITUTION:When an object to be checked is being photographed, a detector 1 as well as an X-ray tube 21 turn around the object P to be checked, and X-ray emitted from the X-ray tube 21 permeates through the object P and comes into the detector 1.

Abstract: PROBLEM TO BE SOLVED: To obtain the subject new compound capable of giving curing products with both low dielectric constant and dissipation factor, useful as e.g. an epoxy resin curing agent, by esterifying the hydroxyl groups of a condensate from a specific resorcinol derivative and carbonyl compound. SOLUTION: First, a condensation reaction is carried out between a (substituted) resorcinol compound of formula I (P is H, a halogen, 1-10C alkyl, 5-10C cycloalkyl, 6-20C aryl or 7-20C aralkyl; (i) is an integer of 0-2) and a carbonyl compound of formula II (X and X' are each H, a 1-10C alkyl, 5-10C cycloalkyl, 6-10C aryl or 7-20C aralkyl, or may be combined with each other into a ring) to form a polyhydric phenol of formula III ((n) is 1-20; R1 to R5 are each the same kind of group as X). Subsequently, at least one OH group of the polyhydric phenol is esterified by an organic acid such as a 1-20C organic polyacid or derivative therefrom, thus obtaining the objective new aryl ester compound capable of giving cured products with both low dielectric constant and dissipation factor, and useful as e.g. an epoxy resin curing agent.

Title: Signal level display device
Inventor: TAHIRA KEIJI
IPC: H04N5/44
Filed: 1996-06-06
Abstract: PROBLEM TO BE SOLVED: To adjust a position of an antenna corresponding to a satellite from which data are to be received through the use of an error rate outputted from a detection means by displaying a signal level onto a display means based on the error rate and allowing a control means to control so as not to minimize the error rate. SOLUTION: In the case of directing a satellite broadcast reception antenna to a satellite, the user switches a satellite broadcast receiver from an on-screen display state into the antenna setting mode. A microcomputer 15 provides an output of a detection level control signal to a demodulation circuit 13 so as to decrease setting of a detection level of a received modulation signal when an error rate is close to an output enable minimum value of an error correction circuit 14 thereby controlling the circuit 13 in a way that the error rate never reaches the minimum value. When the error rate is not close to the minimum value, a computer 15 stops decreasing the setting of the detection level of an input modulation signal to the circuit 14 once.  When the antenna is accurately directed to the satellite and the error rate again reaches the minimum value, the computer 15 allows a display section 16 to display it that the error rate is the minimum value.

Title: Manufacturing method of wire contained flux
Inventor: KIMURA YOSHIO
IPC: B23K35/40
Filed: 1979-11-07
Abstract: PURPOSE:To enable supply of the titled high quality wire at a low price by specifying reduction of area of wire drawing using band steel rolled specifically after removing scales from hot rolled band steel as casing material and slitting the steel to a width specified. CONSTITUTION:After removing scales from hot rolled band steel and cleaning its surface, it is slit to a width specified. Next, thickness adjustment rolling is made to keep the accuracy of a flux rate of a wire within the allowable tolerance. To secure that effect, rolling reduction is set to more than the thickness allowable tolerance, namely over 10%. However, if it is too big, work hardening is caused, and forming in the following process and workability of drawing are lowered. So, rolling reduction is set to below 60%, and at that time, tensile strength of band steel is put to below 60kg/mm.<2> from the same idea. By doing so, a possiblity that the finished product becomes too hard and too strong is removed. While bend-forming of this band steel to U shape, a flux is put in its inside. After forming to pipe shape, wire drawing is made so that work hardening is not too big keeping reduction of area against band steel before adjustment rolling below 95%, and the product is obtained.

Abstract: PURPOSE:To discriminate correctly and quickly types of oil in an oil supply tank by sucking gas which is pushed out of the oil supply tank by exhaustion of air through an exhaust port and detecting the gas thus pushed out of the oil supply tank by means of a gas sensor. CONSTITUTION:When a discharge tube of a nozzle member is inserted into an oil supply port 14 of an oil supply tube 13, a cover member 25 contracts and retires in the axial direction so that the other end part 40 which is in contact with a flange 26 displaces on one end part 39 side, whereby a valve bar 41 is pushed through a spring 42 and a valve body 33 is displaced against a spring force of a compression coil spring 43. As a result, a tube passage 29 comes to communicate with a valve room 34 so that pressed air through a tube passage 31 is supplied through the tube passage 29 from an exhaust port 28 into a storing space 36 of a fuel tank 9. In this way, when air is supplied from the exhaust port 28, gas, passing through the oil supply tube 13 within the storing space 36, flows into a tube passage 22 from a flow-in port 21. Diluted on the way by air from a tube passage 35, the gas is led to a gas sensor 46 to undergo oil type inversion.

Filed: 1989-06-06
Abstract: PURPOSE:To eliminate the need for setting another radio equipment for transmitting data and to transfer data on burden just by making a vehicle approach to a destination by providing a data transmitting function in an approach sensor system. CONSTITUTION:A sensor 5 calculates a propagating time that is from transmit ting a microwave till returning after it is reflected from an obstacle 1 and measures approaching degree, then outputs information on approaching.

Abstract: PURPOSE:To display an invariably accurate aperture value at any time even during the operation of a preview mechanism by correcting the aperture value displayed on a display means on the basis of lens information from a lens information output means when it is decided that the preview mechanism is in operation.
