Title: Pc card
Inventor: YAMASHITA SHIRO
IPC: B42D15/10
Filed: 1995-10-16
Abstract: PROBLEM TO BE SOLVED: To make a PC card high in package density by solving the problem that other electronic parts can not be arranged on both the sides of a circuit board in the packaging area of a crystal oscillator and a conduct spring in the PC card having a structure in which the circuit board is adhered to a card frame and metal plates are provided above and below the circuit board. SOLUTION: A crystal oscillator 106 and a conduct spring 108 are arranged while being combined, and the exterior part of the crystal oscillator 106 is used as the electric conducting means of upper and lower metal plates similarly to the conduct spring 108 as well and connected to the ground potential of the circuit board. The crystal oscillator 106 and the conduct spring 108 are soldered, electrically conducted and fixed. Soldering is executed only one side of the contact part between the crystal oscillator 106 and the conduct spring 108. Since one side of the contact part is operated as a movable part because of this soldering, the conduction is prevented from being defective by deforming the spring, and a hermetic seal is prevented from being destroyed due to application of pressure to the cylinder of the crystal oscillator 106.

Title: Redundancy system changeover system for phase locked loop circuit
Inventor: HAGIWARA YUKIO
IPC: H04B1/74
Filed: 1991-10-16
Abstract: PURPOSE:To match the phases and the frequencies of phase locked loop circuits of each of redundancy systems (0, 1 systems) when an external reference frequency is interrupted by allowing the phase locked loop circuit of a slave system to phase-synchronize with a phase synchronization circuit of a master system. CONSTITUTION:When an external reference frequency (fREF) is interrupted, the changeover control is implemented for the reference frequency, in which the frequency outputted from phase locked loop circuits 6, 16 of its own system is used for a major frequency and the frequency outputted from phase locked loop circuits 6, 16 of the other system is used for a sub frequency. As a result, when the external reference frequency (fREF) is interrupted, the phase locked loop circuits 16, 6 of the slave system are phase-synchronized with the phase locked loop circuits 6, 16 of the master system. As a result, even when the redundancy systems 0, 1 are switched, the difference from the frequency and phase in output signals of the phase locked loop circuits 6, 16 are not caused. Thus, the frequencies and the phases of the phase locked loop circuits of each of the redundancy systems are matched when the external reference frequency (fREF) is interrupted.

Title: Air-fuel ratio control method of internal combustion engine
Inventor: MIYASHITA YUKIO
IPC: F02D41/14
Filed: 1990-10-05
Abstract: PURPOSE:To prevent deterioration of operational properly caused by lean condition of a supplied air-fuel ratio taking place suddenly just after increasing acceleration by setting air-fuel ratio compensation speed by feedback control to a small value when it is under a specified acceleration operational condition. CONSTITUTION:Air-fuel ratio of air-mixture supplied to an engine 1 is feedback- controlled to a target air-fuel ratio by using an oxygen concentration sensor 15 provided in the exhaust pipe 13 of the engine 1 and having output characteristic approximately proportional to exhaust gas concentration. At the time of a specified acceleration operation of the engine 1, fuel quantity supplied to the engine 1 is increased. Compensation speed of the air-fuel ratio by the feedback control when the engine 1 is under a specified acceleration operational condition is set to a value smaller than that in the other operation conditions. Consequently, since the supplied air-fuel ratio gradually follows the target air- fuel ratio, the supplied air-fuel ratio just after increase of acceleration can be prevented from becoming lean, and thereby causing deterioration of operational property.

Filed: 1984-12-19
Abstract: PURPOSE:To attain to enhance stability, by performing not only the correction of reference voltage for detecting hardness leakage, every when the regeneration of hard water softening apparatus is completed, by utilizing a hardness ion electrode and a comparing electrode but also the inspection of the presence of the deterioration of the hardness ion electrode. CONSTITUTION:Reference voltage B for detecting hardness leakage is set to be stored in an inspection device 6 prior to operation and, subsequently, the differential voltage of measured voltage A at the beginning of the operation of a hard water softening apparatus and reference voltage B is stored in said inspection device 6 as initial set differential voltage D. The inspection device 6 compares the measured voltage A between a hardness ion electrode 3 and a comparing electrode 4 with reference voltage B at the supply time of water and, if reference voltage B is larger, outputs an alarm signal of hardness leakage and receives a regeneration completion timing signal from a control valve 5, because the hardness ion electrode 3 deteriorates with the elapse of time and changes in its voltage, to perform the correction of reference voltage B so that the difference between measured voltage A and reference voltage B is adjusted to differential voltage D at the time of initial setting at the start time of water supply when softening is performed certainly. By this method, stability can be enhanced.
