Title: Method for controlling optical power for optical transmission signal in wavelength division multiplexing system
Inventor: ROSER BENEDICT ERHART JOSEPH M
IPC: H04B10/564
Filed: 1999-10-12
Abstract: PROBLEM TO BE SOLVED: To control the optical power of an optical transmission signal by adding an optical control signal, having a variable optical power and spreading a related power spectrum density of the optical control signal. SOLUTION: A light source λX emits a light of wavelength different from that used in an optical channel of wavelength division multiplexing(WDM). A coupler 2 connects a small amount of energy of an optical transmission signal OS and control maintains it to a specified energy level. A control means 3 detects the fluctuation of an optical power of the optical transmission signal OS and in response to this fluctuation, controls the light source λx through an electric connection C. An output P of the light source λx is connected to a wavelength division multiplexer 1 by an optical fiber, the optical control signal of the light source λx is added to the optical transmission signal OS. In this way, the optical control signal having a variable optical power is added and a related power spectrum density of the optical control signal is spread.

Title: Head mount type stereoscopic image display device
Inventor: FUJIYAMA YASUTOMO
IPC: H04N13/239
Filed: 1995-10-12
Abstract: PROBLEM TO BE SOLVED: To simplify the structure and reduce the weight and power consumption, easily fix an observation area, and stably observe a stereoscopic image by splitting luminous flux emitted from right and left striped pixels and projecting it on a concave mirror, and forming virtual images of parallax images with luminous flux reflected by the concave surface mirror. SOLUTION: The luminous flux from the right and left striped pixels which is projected on the concave surface mirror 8 is reflected by the concave surface mirror 8 to form virtual images 11 of striped images displayed on a display element 1 in front of an observer at a distance. The luminous flux from the right and left striped pixels on the display element 1 is directed differently when exiting from a lenticular lens 3, so the luminous flux from the left and right striped pixels form the virtual images L' and R' at the same position to the same size. The virtual images L' and R' can be observed with the left eye 4L and right eye 4R while completely separated. Therefore, the observer recognizes the virtual images L' and R' of the parallax images as a stereoscopic image through the retinae and brain.

Title: Lock-up clutch for torque converter
Inventor: CHIBA HIROTAKA
IPC: F16H45/02
Filed: 1990-10-26
Abstract: PURPOSE:To enlarge the capacity of a clutch at the lock-up time and reduce the elapsed change of a frictional characteristic by providing wet friction facing material on one of a lock-up piston and a converter cover, and specifying the surface hardness and surface roughness of the other corresponding friction face. CONSTITUTION:Annular wet friction facing material 33 is fixed, by bonding, to the other peripheral edge part of a lock-up piston 13. Surface finishing is then applied in such a way that the surface roughness of the corresponding friction face 23, pressed by the friction facing material 33 at the lock-up time, of a converter cover 3 is less than 0.1mum in centerline average roughness (Ra), and the surface hardness is made more than Hv600 in Vickers hardness by applying chrome-plating. Since the surface roughness of the corresponding friction face 23 is small, sufficient real contact area can be secured at the lock-up time, so that the high coefficient of friction can be obtained. The wear of the wet friction facing material 33 is small, and the wear of the corresponding friction face 23 is also small, so that the change of a frictional characteristic can be also suppressed to be small.

Title: Semiconductor memory
Inventor: SHIRAI AKIHIRO
IPC: G06F21/62
Filed: 1991-10-08
Abstract: PURPOSE:To prevent data in a ROM from being easily analyzed and copied by constituting the device so that an external password is inputted to a password comparing/discriminating circuit, and in the case it coincides with a password in a password storage circuit, the data transferred to an output buffer. CONSTITUTION:From an address input terminal 6, an external password is inputted, compared and discriminated by an internal password in a password storage circuit 1 and a password comparing/discriminating circuit 2, and when both passwords coincide with each other, a data output from a pre-amplifier is transferred to an output buffer 4 of a post-stage by an AND gate 3, and data in a ROM is fetched from an output terminal 5. On the other hand, in the case it is decided by that password comparing/discriminating circuit 2 that the external password does not coincide with the interval password, an output of the AND gate 3 becomes a fixed state, the data is not transferred to the output buffer 4 of the post-stage, and the data output is not outputted from the output terminal 5.

Title: Wave-breaking type caisson for breakwater
Inventor: TANAKA HIROYOSHI
IPC: E02B3/06
Filed: 1985-12-25
Abstract: PURPOSE:To lessen the effect of waves on the foot-protecting blocks of a caisson as well as raise the wave-breaking effect of the caisson by a method in which a gentle slope with many beads is formed on the outside of a caisson for breakwater and a hipped portion is formed on the front end of the outside of the slope. CONSTITUTION:A gentle slope 5 with many beads 6 is formed on the outside of a caisson body 1, and a hipped portion 7 is formed on the front end of the outside of the slope 5. A drain chamber leading to the inside of port through a drain hole 11 is provided on the back side of the slope 5. When waves dash against the caisson body 1, the energy of waves is lost by the rise of waves onto the slope 5 and the collision of waves with the beads 6. Furthermore, the ebb tide drops farther from the front of the caisson body 1 by the hipped portion 7, and therefore, the force of fluid acting on the foot-protecting blocks 14 is reduced.

Abstract: PURPOSE:To reduce the influence of the process variance, etc. and to stabilize the working of semiconductor memory is reading by connecting the same number of memory cells to a pair of data lines respectively and precharging these data lines up to a voltage level lower than the power supply voltage to detect the potential difference produced between both data lines by a sense amplifier. CONSTITUTION:The same number of memory cells 2 are connected to a pair of data DL respectively and these lines are precharged up to a voltage level lower then the power supply voltage. The voltage of a level higher than the precharged voltage is written into the memory cell 2 selected in the data writ ing. The potential difference caused between both data lines DL is detected by a sense amplifier based on the potential read out to the data line DL at one side from the cell 2 selected in the data reading. Thus a dummy cell can be omitted and therefore the influence of the process variance, etc., is reduced and the working of a semiconductor memory is stabilized in the data reading. In addition, the size of the memory can be reduced.

Title: Data transfer control circuit
Inventor: KIKUCHI HITOSHI
IPC: H04L69/40
Filed: 1987-11-20
Abstract: PURPOSE:To minimize the range of a fault by monitoring the state of an external equipment by a fault monitor circuit and using a switching circuit to disconnect an external equipment having a fault so as to exclude it from a connection object. CONSTITUTION:If a fault takes place to any external equipment (e.g., an external equipment 2-1 in this case), a central processing unit 21 in the external equipment 2-1 detects the fault in its own equipment and sends a fault signal via a fault monitor line S#1. With a fault monitor circuit 15 in a data transfer control circuit 1 receiving the fault signal, a central processing unit 11 controls a switching circuit 14, which disconnects a transmission line T#1 and a reception line R#1. Thus, the external equipment 2-1 is excluded from the connection object applied with data transmission and a transmission signal from a serial controller 13 in the data transfer control circuit 1 is transferred to an external equipment 2-2 first via a transmission line T#2. Thus, the range of the fault is minimized.
