Title: Sample cell for infrared spectrochemical analysis
Inventor: TAKAHASHI KENICHI
IPC: G01N21/35
Filed: 1987-06-04
Abstract: PURPOSE:To increase the quantity of the light which can be effectively utilized out of incident light by constituting a sample cell in such a manner that the light emitting end and light receiving end of IR optical fibers align to the focal position of a concave mirror having a high-reflectivity inside surface. CONSTITUTION:The light emitted from the light emitting end S of the IR optical fiber G1 for incident light is reflected by the concave mirror 6 and is made into the collimated beam of light parallel with the axis. This light is reflected again by the concave mirror 6 on the light receiving side and arrives at the light receiving end T of the IR optical fiber G2 for detection. Then, the quantity of the light propagating from the light emitting end S to the light receiving end T increases. The reason thereof lies in that the light advancing rectilinearly from the light emitting end S to the light receiving end T along the axis and the light reflected by the concave mirror 6 are both combined and this combined light arrives at the light receiving end T. The formation of the collimated beam of light by the reflection on the concave mirror 6 can be said only with the paraxial ray. All the reflected beams of light can be made into the collimated beams of light by adopting a concave paraboloid to the concave mirror 6.

IPC: H01Q1/12
Filed: 1989-06-03
Abstract: PURPOSE: To obtain a high signal gain by minimizing both signal loss generated when a signal is transmitted and a decrease in standing wave ratio which is normally generated on a transmission line. CONSTITUTION: For example, a vehicle communication antenna system is equipped with a radiation element having 1st to 3rd radiation parts 18, 20, and 22 which are arrayed on the same straight line. Those 1st and 2nd radiation parts 18 and 20 have electrically effective length which is nearly equal to 5/8 wavelength and the 3rd radiation part 22 has electrically effective length which is nearly equal to 1/4 wavelength. The radiation parts 18, 20, and 22 are electrically connected to their adjacent parts by a phase induction element 24 so that electric signals radiated from them have specific position relation. Further, the 3rd radiation part 22 has larger radiation surface area than any of 1st and 2nd radiation parts 18 and 20. Consequently, the high signal gain is obtained.

Abstract: PURPOSE:To enable indication of correct time without controlling fine oscillation frequency of an oscillator by measuring the frequency error of each oscillator, storing the time error factors based on the frequency error in a memory, and correcting the time. CONSTITUTION:The oscillation output from a quartz oscillator 1 is supplied to a frequency divider 6 to count with a date and time counter 8, and second, minute, hour, day of the week, date, month and year are calculated to send to a calculator 10.

That is, by measuring the oscillation frequency from a terminal 7 in advance to get the error DELTAf of the oscillation frequency f from the reference frequency f0, i.e. DELTAf=¦f-f0¦, the time error factor is obtained with the DELTAf to store. When the power is turned on, a time register 16 sends the time data used previously by the components to the calculator 10. The calculator 10 calculates the remaining period from the registered 16 data and the initiation of using time, and then calculates the time error to be produced in the remaining period from the time error factor in the memory 12. It then corrects a counter 8 by way of a control register 11.

Abstract: PURPOSE:To prevent rotation of a key top even when a gap necessary for a key stem to slide is formed by forming a post installed in a base part in parallel to a key stem and a guide hole formed in a frame which guides the post. CONSTITUTION:A post 43 is formed in the end part of an upper plane of a base part 31. The post 43 is in parallel to a key stem 27 and the diameter in the base and the tip part is the same. A guide hole 44 is formed in a key position of a frame 21 corresponding to the post 43.
