Title: Process for producing new, non-reverting living vaccine against shigella
Inventor: STOCKER BRUCE ARNOLD D
IPC: A61K39/112
Filed: 1989-03-02
Abstract: Live vaccines are provided and methods for preparing the live vaccines for protection of a host from a pathogenic microorganism. The vaccines are prepared by introducing at least one modification in a gene involved in at least one, normally at least two, biosynthetic pathways involving the production of products which are unlikely to be found in the disease susceptible host. The modification results in a gene change which cannot be repaired by a single step, e.g. polynucleotide deletions and inversions. Where the aro gene suffers such a change, the resultant auxotrophic mutants require aromatic amino acids, p-aminobenzoic acid and 2,3-dihydroxybenzoic acid or a highly concentrated source of absorbable iron. The auxotrophic mutations have substantially reduced or nonexistent virulence while retaining the desired immunogenicity to initiate the immunogenic response. Various techniques can be employed for providing the desired change.

Abstract: PURPOSE:To form a titanium silicide layer and a TiN layer having specified thicknesses, by arranging a first TiN layer formed on a titanium silicide layer, a second TiN layer formed on the first TiN layer, and a metal wiring layer formed on the second TiN layer. CONSTITUTION:At the bottom part of a contact hole, Si of an impurity diffusion layer 101 is made to react with a first Ti layer 104, thereby forming a titanium silicide layer 107. RTN is performed at 750 deg.C for 30 seconds in a nitrogen atmosphere or an ammonia atmosphere, and a second TiN layer 106 is nitrided, thereby forming TiN. Hence a thick TiN layer 108 is formed by the second Ti layer 106 which has turned into TiN and the thin TiN layer 104. In this case, the ratio of film thickness of the thick TiN layer 108 and the titanium silicide layer 107 at the bottom of the contact hole is determined by the ratio of film thickness of the first Ti layer 104, a thin TiN layer 105 and the second Ti layer 106, and a constant film thickness ratio can be maintained when the temperature of heat treatment is changed.

Title: Measuring device for space volume in container and measuring method
Inventor: TANAKA YOSHINORI
IPC: G01F22/02
Filed: 1994-01-11
Abstract: PURPOSE:To carry out the stable measurement of space volume even in the case where a content vibrates or is foamy or liquid by forming a sealed up space with a container and the gas accomodating section of a compressor, and regularly changing pressure in the sealed-up space to indirectly measure the size of space volume from the height of pressure. CONSTITUTION:A piston 54 is pulled up to the highest point, and a container 80 filled with a liquid makeup 90 is carried below an attaching section 53 with an opening part 81 upward. A compressing device 50 is lowered, and a connection part 53 is tightly attached to the opening part 81 of the container 80, and a cylinder chamber 51 and the space of the container 80 are made to communicate mutually to form a sealed-up space. At this point of time, pressure in the cylinder chamber 51 is the atmospheric pressure. Next, the piston 54 is pulled down to the lowest point to decrease the volume of the cylinder chamber 51 to a fixed volume, and the pressure at this time in the cylinder chamber 51 is measured by a pressure sensor 55. The suitability of the space volume of the container 80 is judged from whether the measured pressure is more than a lower limit value or not. For instance, when it is less than the lower limit value, the space volume is judged to be too large.

Abstract: PURPOSE:To operate a signal source device even from a location where a remote control signal does not directly reach by sending the remote control signal to the signal source device through a repeater installed corresponding to each terminal equipment and supplying a selected source to the terminal equipment. CONSTITUTION:When the user in a room B applies FM broadcast listening remote control operation of a tuner 13, a relevant remote control signal is sent from a remote transmitter 70 and received by a repeater 60 in the room B. The repeater 60 uses a signal decision circuit section so as to decide a command content of the received remote control signal and the information being the result of selecting an audio system source is outputted to a power supply control section. The power supply control section based on the information applies the processing energizing the power supply for a speaker system 22. Furthermore, the relay control section of the repeater 60 sends the received remote control signal to a 2nd repeater 80 in a room A via a remote control signal relay line. Thus, the terminal equipment 30 in the room B listens to the FM broadcast.
