Title: Method and instrument for measuring optical performance
Inventor: ARIGA SUSUMU
IPC: G01M11/02
Filed: 1991-06-28
Abstract: PURPOSE:To measure the MTF of an optical system to be inspected with high accuracy. CONSTITUTION:This optical performance measuring instrument 1 is provided with an interferometer section 2 which measures the transmitted wavefront aberration of an optical system to be inspected, flare measuring section 3 which measures the flare factor of the optical system, arithmetic section 4 which calculates the MTF of the optical system from the transmitted wavefront aberration and an MTF which takes the flare factor into account from the MTF of the optical system and flare factor, and displaying section 5 which displays the MTF calculated by the section 4. Since the arithmetic section 4 calculates the MTF value which takes the flare factor of the optical system into account from M=2XM0/(2+Ex(1+M0)), the MTF of the optical system to be inspected can be measured with high accuracy.

Title: Method for correcting amplitude and phase distortions in both bqualizer and transmission system
Inventor: PIITAA EDOUAADO CHIYADOUITSUKU
IPC: H04B1/10
Filed: 1994-07-14
Abstract: PURPOSE: To make such phase and amplitude distortion that are caused by a multi-propagation effect correctable with a receiver by measuring the phase and amplitude disturbances which occur with time in a calibration stage and finding a phase and amplitude compensating factors, and then, impressing the factors upon a correcting means. CONSTITUTION: A channel sounding pulse is received by means of a receiver 20, converted into an IF by means of a mixer 22, and sent to an equalizer 40 through a line 23. The equalizer 40 converts the IF into a logarithmic amplified signal on the output terminal 39 of a logarithmic amplifier 26. On the other hand, the IF is converted into a limited linear amplified signal on the output terminal 29 of the amplifier 26. The output signal from the output terminal 29 is inputted to a phase detecting means 32 and compared with the delayed signal of the signal itself which is delayed through a delay line 28. The phase difference output of a phase detector 30 and amplitude correction difference from the amplifier 26 are inputted to a correcting means 50 and the means 50 outputs the differences after correcting the phase and amplitude distortion of the signals.

Title: Keyboard
Inventor: NAGOSHI KOYO
IPC: G10H1/34
Filed: 1991-06-29
Abstract: PURPOSE:To more lighten a keyboard without lengthening an arm length. CONSTITUTION:The clockwise rotation of a key 2 with a shaft 4 as a center by key-depressing operation, causes an upper plate 11 of the key 2 to press a pressed projection 25 of a light first arm 22, rotating the first arm 22 in a clockwise direction with a shaft 29 as a center; and causes a linking pin 26 push up a hole wall surface of a linking long hole 33, rotating a second arm 23 in a counterclockwise direction with a shaft 36 as a center against the weight of a weight 34. At that time, the resistant force of the second arm 23, about to rotate in the clockwise direction by the weight of the weight 34, acts on the first arm 22 via the linking pin 26, and moreover acts as an action load on the upper plate 11 of the key 2 via the pressed projection 25. This can more lighten a keyboard without lengthening the lengths of the first and the second arms 22 and 23 compared with a case when one arm is used.

IPC: B65D43/00
Filed: 1989-07-18
Abstract: PURPOSE:To securely hold small parts by a method wherein a part of a surface corresponding to a lid storage hole is cut, and on a remaining part of the cut, an elastic support piece comprising a pressing part for elastically applying force to the upper face of a small part and a narrow spring part extended in the periphery of said pressing part is formed. CONSTITUTION:In a container 1, a small part 4 is stored in a storage hole 20 and then a lid 3 is assembled to a container body 2 so that a pressing part 60 is pushed up by the small part 4 and a spring is deformed in bellows shape. Thus the spring 61 in bellows shape functions as a tensile spring against push-up force so that the small part 4 is elastically pushed toward the storage hole 20 via the pressing part 60. Such an elastic force applying structure is similar in other elastic supporting piece formation parts. Therefore, in such embodiment, respective elastic support pieces 6 individually apply elastic force to respective small parts 4 so that even if there is difference in height among the small parts 4, all the small parts 4 can be securely held.
