Filed: 1992-01-31
Abstract: PURPOSE:To provide a car-body front structure of an automobile, in which a stabilized action of an air bag device is expected, and which is capable of coping with the change in surrounding structures to obtain a desired acceleration wave form. CONSTITUTION:A pipe 9 is arranged and installed in the inside of a front side member 4, and one end part 9a of the pipe 9 is bolted integrally to the front side member in a cantilevered state through a bracket 7 with bolts 8. The pipe 9 is fixed to a lower member 2 of rigid-body construction in the cantilevered state, and when a collision occurs, the other end part 9b of the pipe 9 receives collision-energy to be vibrated to produce an acceleration wave form. The acceleration wave form can be obtained without being influenced by surrounding structures, since one end part 9a of the pipe 9 is fixed to the lower member 2. Thus, when shape, etc., are once set to obtain a desired acceleration wave form, there is no need to change the pipe 9 even when the surrounding structures are changed. Since the adequate acceleration wave form can be obtained, a stabilized action of an air bag device can be expected.

Filed: 1998-02-24
Abstract: PROBLEM TO BE SOLVED: To provide a new display mode capable of solving both of the darkness of the display of a liquid crystal device using two polarizing plates and the degradation of the visibility of the liquid crystal device using a scattering mode in a reflection type liquid crystal device. SOLUTION: In the liquid crystal layer 30 of a high-molecular distributed type, by controlling the alignment angle (ϕ), a twist angle (θ) and retardation (Δn.d), when the liquid crystal layer 30 is in a light transmission state, linearly polarized light P passed through the polarizing plate 40 and made incident on the liquid crystal layer 30 is passed through the liquid crystal layer 30 and becomes almost circularly polarized light C on the surface of a reflection electrode 21. When the circularly polarized light C is reflected on the reflection surface of the reflection electrode 21 and then passed through the liquid crystal layer 30 again, it becomes the linearly polarized light A provided with a polarization direction almost orthogonal to the initial linearly polarized light P.

Title: Mounting method of semiconductor device
Inventor: OTSUKA AKIO
IPC: H05K3/34
Filed: 1992-02-28
Abstract: PURPOSE:To prevent the occurrence of a crack and lowering of moisture resistance by directly attaching a previously molten solder to the position where a lead part and pad are in contact with each other. CONSTITUTION:After adhesive 5 is used in the predetermined position of a substrate 3 to fix the resin part 12 of a semiconductor device 1, a dispenser 6 is used to drip solder 8 molten by a heater 7 along a predetermined direction to directly supply the solder to the lead part 2 of the semiconductor device 1. However, because the lead space of the semiconductor device 1 becomes narrower with the higher integration of a surface-mounting substrate, the quantity of the molten solder 8 to be supplied to the lead part 2 must be reduced for the purpose of preventing inconveniences such as solder bridge. In this case, the heat capacity of the molten solder 8 cannot appropriately solder a pad 4 and lead part 2. Such drawback can be prevented when the substrate 3 is preheated by an infrared heater 9, hot air or the like. Thus, it is possible to prevent the occurrence of a crack and lowering of moisture resistance.

Title: Optical disk device
Inventor: YOSHIMOTO KYOSUKE
IPC: G11B7/09
Filed: 1990-02-22
Abstract: PURPOSE:To obtain the optimum correction value at each time point by storing the correction value of a servo circuit for each area of a disk and controlling the irradiation state of a beam of each area based on the stored correction value. CONSTITUTION:Both maximum and minimum values of a tracking sensor signal obtained from crossing through a track are obtained for each of areas 1 - 16 of an optical disk. Then a microprocessor calculates an amplitude from the maximum and minimum values of the tracking sensor signal and stores the sensor gain in a memory so as to secure a constant amplitude. In a tracking mode the gain is updated based on the sensor gain. For instance, the amplitude of a reproduced signal of a large dynamic range is shown at the left and the output of a small dynamic range set after updating the gain is shown at the right respectively. In this diagram, -6 - 0dB is set at the -3dB gain to the amplitude input of -6dB - +6dB and then at the +3dB gain to the input of 0dB - +6dB respectively in terms of a standard amplitude 1. Therefore the sensor amplitude is set within a range of -3dB - +3dB to the amplitude 1 after the gain is switched. Thus the optimum correction value is obtained.

Filed: 1979-04-10
Abstract: PURPOSE: To reduce the amount of NO x  produced at the time of low-load and high- load operation of an engine by means of air-fuel ratio controlling system in which the amount of bleed-air to carburetor is feedback controlled by use of a signal from an exhaust-gas sensor, by controlling to make mixture richer during the while when the signal from the exhaust-gas sensor indicates that the actual air-fuel ratio is higher than an aimed air-fuel ratio.  
     CONSTITUTION: An auxiliary air-bleed passage 12 having electromagnetic valve 7 is communicated to main and slow-speed fuel passages of carburetor 6 for controlling the air-fuel ratio. On the other hand, signals from sensor 10 for detecting partial vacuum in the intake pipe, intake pressure sensor 11 and exhaust-gas sensor 3 are afforded to control circuit 9 for controlling the opening of electromagnetic valve 7, so as to attain an optimal efficiency of ternary ctalyst 4 in exhaut pipe 2. In the control circuit 9, the actual air-fuel ratio calculated from the above signals is compared with an aimed air-fuel ratio. The control circuit 9 is operated to make the time change of the integration signal greater (that is, to make the aimed air-fuel ratio smaller) during the while when air-fuel ratio of exhaust gas is greater than the aimed air-fuel ratio. This period corresponds to low- and high-load operation of engine, and the system operates to reduce the amount of NO x  produced in this period.
