Abstract: PURPOSE:To obtain a diaphragm with large bending magnitude where silicon carbide is the essential component by holding the sintered base material which is obtained under heat and pressure of mixed powder of silicon powder and graphite powder in a heat decomposing furnace, and carbonization-burning the base material in high pressure reaction gas atmosphere. CONSTITUTION:A mixed powder 5 obtained by adding and mixing 30-40mol% graphite with the same-degree paticle size to silicon ultrafine powder with <=3mum particle size is placed between wolfram diaphragm molds 1 and 1' and a mold frame 2 of a sintering molding device, and high frequency electric power is impressed from a high frequency power source 4. While the mixed powder is heated at 1,300-1,400 deg.C, it is applied with 2Kbar pressure, it is sintered-molded in the diaphragm, and a sintered-base material 6 is obtained. Then, the base material 6 is held in a heat decomposing furnace main body 9, and inert gas is introduced after exhausted to the prescribed degree of vacuum.

Title: Optical scanning type displacement measuring equipment
Inventor: HIRONO ATSUYUKI
IPC: G01B11/03
Filed: 1994-10-05
Abstract: PURPOSE:To make wall-reproductive measurement without forming a dead angle and changing measuring precision with a position and still easily change a scanning range with the size of a measured material by providing a light projecting means, a light receiving means, a signal processing part and a scanning means. CONSTITUTION:A light projecting means 1 and a light receiving means 2 are fixed to a frame 3 and a projection spot is scanned on a measured material 10 by the travel of the frame 3. The direction of light beam is set perpendicular to the main plane of the measured material 10, so that no dead angle can be formed regardless of the surface roughness of the measured material 10. As the light beam can be approximately perpendicular to the main plane of the measured material 10 located at any position, even if the diameter of the light beam changes with distances, can be held constant at the same distance, no measuring precision is changed with a position and well-reproductive measurement can be made. In addition, any size of measured material 10 is applicable if the travel range of the frame 3 is mad to correspond to the measured material 10.

Title: Automatic answering telephone set
Inventor: KITAMURA TETSUO
IPC: H04M1/65
Filed: 1993-09-28
Abstract: PURPOSE:To prevent malfunction even when a DTMF signal is reproduced in the remote reproduction mode. CONSTITUTION:A timer 5 starts time count as soon as automatic message recording is started. When a DTMF signal is received during the recording, a recording time counted by the timer 5 is stored in a RAM 4. The remote mode is set by the reception of the DTMF signal and the recorded content is reproduced in the remote mode. As soon as the remote reproduction is started, the timer 5 starts counting the time. When the DTMF signal is inputted during the remote reproduction mode and the recording time is stored in the RAM 4, the recording time is compared with the counted reproduction time. When the recording time is coincident with the reproduction time as the result of comparison, the DTMF signal is discriminated to be the reproduced DTMF signal and the remote reproduction mode is continued. When no recording time is stored in the RAM 4 and the recording time and the reproduction time are dissident, the DTMF signal is discriminated to be the DTMF signal received externally and the remote mode is executed.

Abstract: PURPOSE:To minimize the variance of a generated code length by repeating the code assigning operation and the distribution degeneration operation until information source elements are two, connecting codes while tracking the history of the degeneration to form a code word and using the correspondence between the information source and the code word as the content of a table. CONSTITUTION:The inputted information is stored once to an input section, the information source element is extracted and the information source element is outputted to a code assigning section 2. The code assigning section 2 assigns codes 0,1 to the two elements of the least significant digit. Then the distribution degeneration section 3 degenerates the two elements at the least significant digit into one element and the sum of the appearance probability of the two elements is used as the appearance probability of the new element. When the number of the information source elements is two in the section 3, an effective cross reference table is outputted at a code word output section 4 and the table is indexed reversely and the result is outputted as a code word reading the code. The code word is written in a coding table 5, a coding section 6 reads sequentially the information from the input section 1 and outputs while applying coding and referencing the coding table 5.
