Title: Stroke and control system for lift cylinder of bulldozer
Inventor: IBUKI TOSHIO
IPC: E02F9/22
Filed: 1986-09-05
Abstract: PURPOSE:To prevent impact from occurring when a lift cylinder reaches stroke end by a method in which when a blade in tilted state is detected to be near the limit of vertically moving range, the flow rate of pressure oil sent to the lift cylinder is slowly reduced. CONSTITUTION:During the rise of a blade 6 in tilted state, the detected output of turning angle sensors 41 and 42 is put in a flow rate correcting controller 11, where on the basis of turning angles detected by the sensors 41 an 42, the lifting amount (l) and tilting amount (t) of the blade 6 are obtained. The lifting range max according to the tilting amount (t) is then obtained and a liftable amount (l') is obtained. When l>=l', a correcting value Q for the flow rate of reduced pressure oil is obtained. When signal showing the value Q is put in NP valve controller 10, the product of the value Q and pressure oil amount shown by command from the operator 9 is obtained and the corresponding flow rate of pressure oil is sent to an oil path 8. The stroke speeds of the cylinder 1 and 2 are slowly reduced and stopped as the blade 6 rises.

Title: Spark plug for internal combustion engine and manufacture thereof
Inventor: OSHIMA TAKAFUMI
IPC: H01T13/20
Filed: 1988-08-25
Abstract: PURPOSE:To make the spark plug good resistive to pollution by use of L=W/20+(M-K) (provided that 2.0<=K<=6.0) where W = thermal conductivity of good thermally conductive ceramic, M = size of thread, L = length of the leg of good thermally conductive ceramic and K = correction factor. CONSTITUTION:In the formula, the unit of W is the W/mk, the unit of M is the mm, and the unit of L is the mm. A center electrode 2 is inserted into the tip of the shaft hole of an insulator 1, and a resistor 4 attaches to conductive glasses 3 with a terminal electrode 5 by placing itself between the conductive glasses 3 such that they are sealed up. This insulator 1 is fixed to the inside of the lumen of a main-body fitting 6 equipped with a set screw through packing, and spark gap is formed between an external side electrode 8 jointed to the end face of the fitting 6 and the center electrode 2. In a case of a plug having such a structure, a plug with a size of thread M of 14mm, a length of leg L of 14m can achieve the purpose by means of an insulator whose thermal conductivity is 70W/mk, but in case of the same length of leg, an insulator having a thermal conductivity of 110W/mk is necessary for M 12mm and an insulator having a thermal conductivity of 150W/mk is necessary for M 10mm. Thereby, it is possible to determine the length of leg and thermal conductivity of an insulator referring to the size of thread.

Title: Information recording medium and information recording and reproducing apparatus
Inventor: YAMANAKA YOSHIHIRO
IPC: G11B20/10
Filed: 1993-08-24
Abstract: PURPOSE:To detect correct synchronous signal if one synchronous signal portion becomes defective by arranging the synchronous signals indicating data read start position in two places keeping a predetermined interval therebetween. CONSTITUTION:An SM portion indicating a sector mark, an ID portion indicating track and sector numbers, a first synchronous signal indicating the heading position of data, a blank area in the predetermined length, a second synchronous signal indicating the heading position of data and a data area for writing data are arranged in this sequence on a recording medium. When the SM detecting circuit 24 detects the first synchronous signal through a head 22 and a recording reproducing circuit 23, a detection allowable signal output circuit 25 sends a signal for inhibiting detection of the second synchronous signal to a synchronous signal detecting circuit 26. In this case, the first synchronous signal is delayed up to the heading position of data with a delay circuit 27. When the first synchronous signal is not detected, the second synchronous signal is allowed to be detected and is then sent to a data read circuit 28 without any delay.

IPC: G05D1/02
Filed: 1985-09-20
Abstract: PURPOSE:To guide correctly a large unmanned multi-axle carrier along a guide line by driving the carrier with coincidence between the guide line of an optional form and a certain point of the front and back parts of the carrier independently of each other. CONSTITUTION:Both the direction and the amount of deflection detected by the front and back deflection detecting means 14 and 15 are supplied to a steering controller 18 for each of the front and back axles 2 and 3.

Abstract: PROBLEM TO BE SOLVED: To reduce noise by providing an engaging part formed of one protruding part and two recessed parts to be fitted thereto, between a crest part end face and a root part end face relative to each other, and fitting one recessed part to the protruding part at the time of transmitting driving force in either normal or reverse direction. SOLUTION: One protruding part 43 protruded to the opposed flange side, and two recessed parts 44, 46 to be fitted thereto are formed at an end face 36a of a crest part 36 and a bottom face 37a of a root part 37 relative to each other at the time of transmitting driving force. The positions of the recessed parts 44 are set in relation to the protruding part 43 so that the protruding part 43 is fitted to the recessed part 46 at the time of normal rotating transmission and that the protruding part 43 is fitted to the recessed part 44 at the time of reverse rotating transmission, thus forming an engaging part 47 for positioning the crest part 36 to the root part 37.

Abstract: PURPOSE:To contrive to improve the thermal efficiency by a method wherein a structure is designed so that a partition is arranged in inclined manner on the back surface of a panel heater and an air flowing directly moved up from the lower part to the upper part is shut off, in a heating device provided with the panel heater for room heating. CONSTITUTION:A partition plate 6 is arranged in inclined manner on the back surface of a panel heater 5, an air flowing directly moved up from the lower part to the upper part is shut off by the partition plate 6, thus, a short air channel 7 is formed. Therefore, the heated and rising air flow is flowed obliquely upward via the channel 7, and discharged to the outside from between the panel heater and a wall 1 in a short time. Thereby, the temperature difference between the lower part and the upper part on the back surface of the panel heater 5 can be decreased, also the temperature distribution can be uniformed. Accordingly, the power-off can be prevented in case that the temperature is increased up to the heat resistant limit at the upper part even when the temperature at the lower part of the panel heater is low. Thereby, the improvement of thermal efficiency can be contrived.
