Title: Crankshaft of internal combustion engine
Inventor: ITOU EIJI
IPC: F16C3/08
Filed: 1980-06-11
Abstract: PURPOSE: To eliminate the weak point of a crankshaft of an internal combustion engine while maintaining the effectiveness of the weight reduction by making solid to strengthen only the part which is the node of the torsional vibration of the crankshaft when making it hollow.  
     CONSTITUTION: The node of the torsional vibration in a crankshaft frequently exists between the last cylinder and the flywheel. Therefore, the weakness for breaking off at the said point is eliminated by making solid the 5th journal part 10w next to the end 10x of a crankshaft 10 at the flywheel side and the 4th pin part 10t. The 7th counterweight 10y and the 8th counterweight 10z are made heavier than the other counterweights to offset the unbalance thus created. The strengthening of the node of the torsional vibration in the crankshaft at the part which needs the strength and rigidity most provides a construction which does not easily breakable by only allowing slight weight increase.

Abstract: PURPOSE:To improve the color reproducibility due to the difference of lightness of red signal, by using a matrix circuit and decreasing the deterioration in the S/N ratio of a luminance signal. CONSTITUTION:A red signal is separated at an addition circuit 20 from a high frequency signal extracted at a BPF17 by using a 1HDL19 and utilizing the correlation of signals at two horizontal scanning periods, a blue signal is separated at a subtraction circuit 21, the red and blue signals are detected at detection circuits 22, 23, they are converted into a low frequency signal at a narrow band LPF.

Filed: 1986-04-07
Abstract: PURPOSE:To easily obtain a master disk having no warpage by using not glass but Ni for a substrate material. CONSTITUTION:A ceramic material 2 such as SiO2 or Al2O3 is sputtered onto an Ni substrate and thereafter, the surface is precisely polished. A resist 3 is coated on such surface and is developed after laser exposing. A sputtered Ni film 4 for a conducting treatment is provided therein and finally said film is subjected to the Ni plating by electroforming. The substrate, the conducting- treated film and the electroforming layer are of the same Ni material if the Ni is used as the substrate material for the master disk in the above-mentioned manner. The ceramic layer such as SiO2 or Al2O3 are laminated to several hundreds mum on the Ni substrate to make the sandwich structure with the electroforming Ni plating layer. On the other hand, the Ni substrate it is thick as 6-10mm and the electroforming Ni plating film is 300-400mum and is measurably thinner than the substrate. Since the materials are the same, the warpage is less generated.

IPC: E02F3/88
Filed: 1999-03-24
Abstract: PROBLEM TO BE SOLVED: To discharge soil left in digging completely and enable highly precise construction work such as foot protection work of pile construction work in digging construction work such as pile construction work. SOLUTION: A crater (slime suction member) 2 in the shape of a cone which is convergent toward an upper opening 5 and is divergent toward a lower opening 6 is mounted in an inner part at a tip of a hollow pipe 1, and the lower opening 6 is arranged on slime. When high pressure air is poured from an air pouring pipe 4 and air is sucked from above the hollow pipe between an inclined outer face of the crater 2 and an inner wall of the hollow pipe 1, pressure inside the crater 2 becomes negative pressure due to abrupt rising stream generated in the vicinity of the upper opening 5 of the crater 2. Slime is sucked by this negative pressure, is conveyed by a rising air stream, and is discharged onto the ground.

IPC: G01G23/42
Filed: 1989-03-30
Abstract: PURPOSE:To improve the operability of registration of exemption object persons by discriminating tax-free commodities and taxable commodities by a tax discriminating means and subtotaling them independently of each other to calculate the amount of tax and the total amount of money after tax. CONSTITUTION:At the time of registering sale data of a commodity, whose sale is registered, in a storage part by the commodity register operation, the amount of sale of this commodity is accumulated in taxable commodity subtotal memories 41 and 42 when the commodity is taxable, but the amount of sale of the commodity is accumulated in a tax-free commodity subtotal memory 43 when it is tax-free. When the closing operation is performed in this state, the amount of tax, the taxable amount of money, and the tax-free amount of money are added to calculate the total amount of money before tax. Thus, the total amount of money after tax is momently calculated with an easy key operation though selling commodities are registered without distinction between taxable commodities and tax-free commodities, and the operability of registration of exemption object persons is improved.

Abstract: PURPOSE:To prevent dangers caused by generation of heat or reckless driving of an output shaft by detecting the time required for that the exciting current of a clutch coil amounts to the regulation value to detect a clutch gap. CONSTITUTION:A control circuit 15 is adapted to excite a clutch coil 6 through a driver 17, start a timer 16 and stop exciting when a time T1 of the timer 16 passes. Subsequently, the control circuit 15 resets the timer 16 to be restarted, again excites theclutch coil 6 when the timer 16 counts up a time T2 when there is no clutch coil current flowing through D2, R1 of a fly wheel circuit, and resets the timer 16 to start. After that, when an output signal Vb of a comparator 20 is inverted from L to H, a result value of the time 16 is input. If the result value is below a preset time T, a gap is judged to be normal, and if it is above T, the gap is judged to be small.
