Patent JP-H0278105-A (JP)
Title: Lighting unit
Inventor: FUNABASHI TADAO
IPC: F21V23/00
Filed: 1988-09-13
Abstract: PURPOSE:To increase security in attaching work for a lamp and make compact its circuit components, by reducing the size of the contact-less conductor panel of a discharge lamp so that fingers may not touch it when attaching the lamp, and placing the conductor panel within the external diameter of the lamp. CONSTITUTION:A lamp 3 is fitted into the socket 4 of a shade 1. The external diameter of a contact-less conductor panel 2 is smaller than that (dotted line) of the lamp 3 so that fingers may not touch the conductor panel 2 while holding the lamp. The distance S between the conductor panel 2 and the lamp 3 is made smaller than the external diameter D of the lamp. This arrangement provides security of the replacement or checking of the lamp and a high damping effect for starting voltage; in addition, the components of its electrical circuit can be made compact so that cost reduction is realized.
Patent JP-H04106442-A (JP)
Title: Pressure sensor
Inventor: KOJIMA TAKAO
IPC: G01L9/12
Filed: 1990-08-28
Abstract: PURPOSE:To eliminate erroneous detection of a pressure and further to enable prevention of the strain of a diaphragm part due to a thermal expansion difference by a construction wherein an outer thickness part on the pressure receiving side facing a vacant space formed in one end part of a ceramic layer is used as a diaphragm part. CONSTITUTION:When a sensor S is disposed with the upper end thereof held and with the lower end exposed in the necessary ambience of a pressure to be detected, a diaphragm 5 is strained in the shape of a depression onto the vacant space 4 side by the pressure to be detected. Thereby a movable electrode 7 is made to approach a detecting electrode 8. Therefore the mutual distance of separation between them becomes small and an electrostatic capacity between the electrodes 7 and 8 which is detected at a conductive end 10b increases. On the other hand, a reference electrode 9 faces the peripheral edge part of the movable electrode 7 in which no strain is generated when the pressure to be detected acts thereon, and even when the depression strain occurs in the diaphragm 5, a distance between the electrodes 7 and 9 does not change and, consequently, the electrostatic capacity between them does not change. By using the electrostatic capacity between the electrodes 7 and 9 as a reference, the amount of a change in the electrostatic capacity between the electrodes 7 and 8 can be detected and the pressure to be detected can be detected correctly.

Filed: 1989-09-04
Abstract: PURPOSE:To widen a lock range by providing a hysteresis comparator, plural inversion detection circuits and a timer circuit, detecting a frequency difference between an input signal and a clock to control a voltage controlled oscillator. CONSTITUTION:An input signal is inputted to a comparator 1 and also a hysteresis comparator 6.

Then the detection outputs are outputted to a voltage controlled oscillator 4 via timer circuits 8, 9 to control the oscillator 4. In such a case, output signals from the circuits 8, 9 represent the frequency difference between the input signal and the clock, and the inverse detection signal in excess of the maximum difference controls the oscillator 4 to decrease the oscillating frequency and the inverse detection signal less than the minimum difference controls the oscillator 4 to increase the oscillating frequency. Then the normal lock state is always attained to widen the lock range, thereby expanding the data transmission speed range.
