Title: Optical wavelength selector and optical communication system
Inventor: SUEMURA TAKEHIKO
IPC: H04B10/00
Filed: 1996-12-18
Abstract: PROBLEM TO BE SOLVED: To make it possible to simplify a wavelength multiplexed optical network structure by separating wavelength multiplexed light into plural pieces of light for every wavelength when the wavelength multiplexed light is inputted and individually outputting to plural pieces of output ports. SOLUTION: 16 waves of wavelength multiplexed light groups inputted from an optical fiber 10 are demultiplexed to four pieces of wavelength multiplexed light for every wavelength group A-D by a light wavelength demultiplexer 20. The wavelength-multiplexed light of the wavelength groups A-D are outputted selectively to the inputs of these wavelength multiplexed light groups by turning semiconductor light amplifiers 40-43 on/off. The wavelength multiplexed light of the wavelength groups A-D outputted in such a manner are received directly by an optical receiver without through an optical filter, etc., since the light of four pieces of wavelengths are outputted respectively from different optical fibers 90-93.  Since four pieces of light constituting the light group selected in such a manner are outputted respectively from different ports, the wavelength multiplexed optical network structure is simplified by using this optical wavelength selector.

Title: Tap-controlled hot-water supplying apparatus
Inventor: OBAYASHI TOSHIHIKO
IPC: F24D17/00
Filed: 1991-11-29
Abstract: PURPOSE:To reduce energy loss by controlling a circulating flow rate based on a difference between an inlet water temperature and a warm-keeping set temperature. CONSTITUTION:When a circulating water temperature is increased by combustion in a burner 3 and the absolute value of a difference between a warm-keeping set temperature and an inlet water temperature has become a second predetermined value or less, the burner 3 is put off and warm-keeping operation is continued for a given period of time set by a timer in a CPU 14. When a difference between the warm- keeping set temperature and the inlet water temperature is lower than a first predetermined value, the flow rate is not regulated and combustion is not started while a condition is retained as it is for a given period of time set in the timer. When a given period of time has elapsed under a condition that the absolute value of the difference between the warm-keeping set temperature and the inlet water temperature is lower than the second predetermined value, a water amount servo valve 13 is controlled to retain the amount of circulating water in a second set flow rate lower than a first set flow rate whereby the amount of dissipating heat from a piping is reduced and the working amount of the circulating pump is reduced. According to this method, energy loss can be reduced.

Title: Sampling clock generator for scanning microscope
Inventor: HAKAMATA KAZUO
IPC: G02B21/06
Filed: 1989-12-27
Abstract: PURPOSE:To prevent the distortion of an image occurring by providing a clock generating means to generate a clock signal with a frequency proportional to the speed of relative displacement. CONSTITUTION:The device is comprised so that a sampling clock with the frequency proportional to the relative speed of an optical system and a sampling board 22 can be generated. In other words, the frequency of a signal S4 is proportional to the travel speed of a movable carriage 15. Therefore, travel speed is set inversely proportional to the sampling cycle of an image signal S, and it results that sampling is performed at every travel with equal pitch of a light spot P in a sample, and digital image data Sd always shows image information at equal gap points on a main scanning line even when the travel speed of the movable carriage 15 is changed. In such a way, no distortion occurs on the image of a microscope generated at an image reproducing device 54 based on the image data Sd.

Title: Semiconductor memory
Inventor: HARADA MOEMI
IPC: G11C11/401
Filed: 1989-12-26
Abstract: PURPOSE:To enable redundancy substitution even when data is written in plural memory cells by providing memory cells for redundancy which can be selected at the same time and a redundancy address decision circuit. CONSTITUTION:The memory cells for redundancy which can be accessed at the same time are used. When an input address other than the input address of a decoder 1 is a redundancy substitution address, the output of a redundancy decision circuit 10 goes up to H level and a decoder 2 is placed in a disabled state. The output of the circuit 10 is processed logically with the output of a selector 30 to control a transfer gate YSW for redundancy. Namely, the gate YSW is turned on when the output of the selector 30 is at H and turned off when at L. Consequently, the memory cells for redundancy are accessed. Thus, a redundancy circuit is obtained which can write data in the memory cells assigned to plural addresses selectively at the same time.

Title: Chassis device for preventing sediment invasion for crawler belt type tractor and its manufacture
Inventor: NAGATA YOSHIHIRO
IPC: B62D55/088
Filed: 1995-12-05
Abstract: PROBLEM TO BE SOLVED: To certainly check the invasion of sediment into a truck frame by forming the truck frame in a downward U-shape, and filling up reinforcing material in a space between the truck frame and a truck roller. SOLUTION: In a state where a truck frame 2a formed in a downward U- shape and a truck roller 3c are mutually assembled, a reinforcing material 2A is filled up in a space inside the truck frame 2a. Since the truck frame is thus composed, sediment flung up from a shoe 3a and a link 3b can be checked from entering through a gap between a truck roller guide 2b and the link 3b into a U-shaped opened part at the lower end of the truck frame 2a. The sediment is thereby discharged below the truck roller 3c, which assists the shoe 3a in its smooth rotation, and the early abrasion of the truck roller 3c and the deformation of the truck frame 2a which are caused by the sediment piled up inside the truck frame 2a can be prevented.
