Title: Ghost eliminator
Inventor: SHIMIZU SEIJI
IPC: H04N5/21
Filed: 1987-01-31
Abstract: PURPOSE:To prevent wiring from being concentrated, by constituting a transversal filter which generates a pseudo ghost component so as to form each step by cascade-connecting in the same structure. CONSTITUTION:An analog television signal is converted to a digital signal at an A/D converter 11, and is inputted to a gain variable type transversal filter 100. Each step of the filter 100 is constituted of variable delay circuits 12a-12n which supply variable delay time to the output of a front step, multipliers 13a-13n which apply weighting on an original television signal, and adders 14a-14n which add the outputs of the variable delay circuits on the outputs of the multipliers and supply them to the next step, and the above stated step is cascade-connected. The transversal filter 100, the tap gain of which being varied based on a ghost included in the television signal, generates the pseudo ghost component.

Title: Injection-type laser
Inventor: SUZAKI WATARU
IPC: H01S5/00
Filed: 1978-02-24
Abstract: PURPOSE: To produce the laser device by lowering both the leak current and the threshold current and at the same time reducing the variation rate of the threshold current which is caused by the temperature rise.  
     CONSTITUTION: The GaAs substrate containing n-type layer 5 and p-type layer 6 is used, and n-GaAlAs2, n-GaAs3 and n-GaAlAs4 are laminated so that the areas of Zn diffusion layer 2', 3' and 4' may be included in layer 6 when the substrate receives the projection from the vertical direction. Thus, a space of less than 5 m can be secured easily between layer 2' and 6, and the electric resistance can be increased considerably to the pn junction contained in layer 2 as well as to pn junction 201. As a result, the pn junction effective area to contribute to the leak current can be reduced down to about 1/50 or so. Accordingly, the current concentrates to pn junction 201, and thus the leak current at the room temperature can be ignored. In this connection, the threshold current features a low and steady value, and the temperature shows a gentle change proportional to the cube of the absolute temperature up to about 70°C or more.

Title: Method for reduction of reinforcing period for load bearing capacity of subsoil
Inventor: UCHIYAMA HIROSHI
IPC: E02D3/10
Filed: 1979-02-27
Abstract: PURPOSE: To accelerate the consolidation and reduce the period of preconsolidation loading by pressure feeding of compressed air into the fluffy-structure subsoil or the honey-comb structure subsoil loaded with preconsolidation.  
     CONSTITUTION: It is found that consolidation will reduce the volume of the subsoil by amount of water exuded from the system and thus, the ground surface lowers accordingly. Though the amount of the water herein exuded, namely the lowering of the ground surface depends on the degree of the consolidation, a considerable period of time is required unitl the lowering ends. To cope with this, a compressed air is fed into the fluffy-structure subsoil or the honey-comb structure subsoil loaded with a preconsolidation to agitate the soil to reduce the strength of the natural soil thereby reducing the period of preconsolidation loading.
