Title: Reflection type liquid crystal overhead projector
Inventor: MORI KEIICHI
IPC: G02F1/1335
Filed: 1991-06-07
Abstract: PURPOSE:To prevent a bright spot from appearing on a screen. CONSTITUTION:A projection part 26 is fitted on one side of the bottom surface of a liquid crystal display unit 18 and a liquid crystal panel 19 slants to a mirror Fresnel lens 12. The image of a light source 15 projected on the surface of the liquid crystal panel 19 is reflected by the liquid crystal panel 19 and reaches a place off a projection lens 16. Therefore, the reflected image of the light source 15 on the surface of the liquid crystal panel never appears as a bright spot on the screen.

Filed: 1990-05-25
Abstract: PURPOSE:To obtain high azimuth resolution by using a transmission reception module and a feeding circuit separately at those usable at a high frequency band and at a low frequency band in two frequency bands, respectively. CONSTITUTION:A 2-frequency resonance element antenna 2 is arranged on arrangement lattice points 3 specified at a low frequency band X in two frequency bands, an element antenna 5 usable to a high frequency band Ka is arranged to the arrangement lattice points with no 2-frequency resonance element antennas 2 arranged thereon so that the lattice points 3 and the arrangement lattice 4 specified at the higher frequency band Ka are overlapped to constitute a 2-frequency common plane array antenna 6. Moreover, modules 22, 23 for high and low frequency use corresponding to the two frequency bands X, Ka and feeding circuits 25, 24 are connected to the 2-frequency common planar array antenna 6. Thus, a beam with an antenna beam width corresponding to each frequency band in the two frequencies is shaped. Thus, the azimuth resolution is improved.

Title: Handrail
Inventor: ENAMI TAKAAKI
IPC: E04F11/18
Filed: 1998-05-19
Abstract: PROBLEM TO BE SOLVED: To prevent the damage of a handrail even when a huge change is generated between buildings, and to allow the handrail to follow displacement by rotatably disposing a handrail member to a support in the horizontal direction and forming the handrail member in an extensible manner. SOLUTION: A handrail member 3 is arranged to supports 2 horizontally rotatably in the handrail 1, and the handrail member 3 is formed in an extensible manner. When the supports 2 are displaced in the right direction by the displacement of a vibration-isolation building, each hinge 31 as joining sections with each support 2 are rotated horizontally in the handrails 3, 3. Load applied to each support 2 and the handrail members 3 is let escape, and these members follow displacement between the vibration-isolation buildings without deforming and damaging these members. When the handrail members 3 are fluctuated to the supports 2, the length of the members 3 is changed. It is because inner pipes 34 follow drawing displacement when each support 2 is moved and the handrail members 3 are pulled since the members 3 consist of the double pipes of outer pipes 33 and the inner pipes 34.  Accordingly, a handrail function can be displayed sufficiently even after the generation of displacement.

Title: Level conversion circuit
Inventor: YAMADA KAZUMI
IPC: H03K5/02
Filed: 1987-05-29
Abstract: PURPOSE:To supply a signal with a sufficient amplitude without amplification by a TTL circuit by holding the amplitude of an input signal as it is at a level conversion circuit so as to obtain an output signal changing with respect to a negative power potential. CONSTITUTION:When an input voltage Vin is given to an input terminal IN, the emitter potential VE is expressed as VE=Vin-VF, where VF is a base- emitter voltage of a transistor (TR) Q1. On the other hand, the collector-emitter voltage of a TR Q2 is expressed as VCE2=i1R+VF (i1 is a current of a current source I1). Thus, a potential Vout at an output terminal OUT is expressed in equation I. When the current i1 is proportional to a negative power voltage VEE, the relation of i1=a.VEE+b is obtained and the output voltage Vout is expressed in equation II. Thus, the amplitude of the output voltage Vout is in accordance with the input signal Vin with respect to the voltage of the power supply VEE. Thus, the output signal has a sufficient amplitude and sufficient noise margin with respect to the threshold value using the power supply VEE as a reference.
