Title: Steering wheel
Inventor: SUGIYAMA YUICHI
IPC: G01L5/00
Filed: 1994-03-28
Abstract: PURPOSE:To collectively load a steering wheel with an air bag device and an impact sensor. CONSTITUTION:Fitting holes are formed in a boss plate 12 of a steering wheel main body 1 at four positions, and an impact sensor 46 is installed by screwing with these fitting holes. An air bag device and the impact sensors 46 are arranged so as to be displaced downward from the center of turning of the steering wheel. The lower side fitting hole is formed in a fitting piece projected downward from the boss plate 12. At the time of collision of an automobile, when the chest of an occupant collides with the lower side of the steering wheel, a lower spoke core 15 is plastically deformed so as to absorb the impact. Consequently, the air bag expanding perfomance can be secured. Even in the case where the steering wheel is loaded with the impact sensor 46, the lower spoke core 15 is plastically deformed by a constant load so as to stably absorb the impact.

Abstract: PURPOSE:To aim at enhancing the productivity, delustering efficiency and feeling of a boot, by forming a resin composition composed of a specified weight parts of a cross-linked polyvinylchrolide group resin having a specified percentage of undissolved tetrahydrafuran and a specified weight parts of a plastic material. CONSTITUTION:A lever boot is made of a resin composition composed of a crosslinked polyvinylchrolide group resin consisting of undissolved tetrahydrafuran, and a plastic material. The undissolved tetrahydrofuran is preferably in the range from 10 to 50%. If it is below 10%, the improved effect of permanent compressed strain and plastic material breed is low, and if it is above 50%, the ability of forming and the condition of delustering of the outer surface of a formed material are unsatisfactory. Further, the plastic material is preferably be in the range from 100 to 150pts.wt. If it below 100pts.wt., the flexiblity is insufficient, and if it is above 150ptw.wt., the unpreferable breed phenomenon of the plastic material is brought about. Further, the cross-linked polyvinylchrolide does mean a mixed resin consisting of partially cross-linked polyvinylchlrolide group resin and polyvinylchrolide group resin.

Abstract: PURPOSE:To make accurate ignition control performable all the time, by determining ignition timing and energizing start timing with the elapse of time ranging from all crank reference positions of integral times of a cylinder number to the ignition timing and the energizing start timing. CONSTITUTION:A reference position detector 8 outputs a crank position, for example, a reference position signal A of H at BTDC50 deg. of each cylinder via a waveform shaping circuit 9.

Thus, rotation at every crank angle 90 deg., namely at every cylinder is detected, and the ignition timing and the energizing start position are operated and outputted so that the ignition timing is surely controllable to engine speed variations.

IPC: G11B7/09
Filed: 1997-03-13
Abstract: PROBLEM TO BE SOLVED: To control a focus with high precision without the influence of a focus signal caused by a quasi-defocus by a method wherein the focus control target values of a land track and a groove track are so set as to have focus error signals zero on a mirror part on a disc where there is no land and no groove. SOLUTION: A differential amplifier 4 calculates a difference between the outputs of an adder 2 and an adder 3 which calculate the respective summations of the luminous powers of pairs of detectors provided on respective orthogonal positions and outputs a focus error signal FE which shows the conversion state of a light beam on a disc. The output is inputted to a differential amplifier 5 which calculates and outputs a difference between the focus error signal FE and the output of a selection circuit 12. When a focus control system reaches a steady state, the error signal outputted from the differential amplifier 4 is converged into an offset value equal to the output of the selection circuit 12. A focus control target value is set by changing the output of the selection circuit 12 as the target value of the focus control.
