Title: Carbon fiber bundle-reinforced silicon carbide sintered body and its production
Inventor: KIKUCHI SHIGERU
IPC: C04B35/56
Filed: 1992-10-07
Abstract: PURPOSE:To increase the strength of a carbon fiber bundle-reinforced silicon carbide sintered body by compounding a carbon fiber bundle made by bundling plural continuous carbon long filaments in the same direction by using carbon as a medium with a silicon carbide matrix to attain the effective orientation of reinforcing fiber for improving the strength in the matrix. CONSTITUTION:This carbon fiber bundle-reinforced silicon carbide sintered body contains the plural continuous carbon fibers in the state of being bundled in one direction by the medium made of carbon. The diameter of the continuous carbon fiber bundle is >=0.05mm and the content of the carbon fiber bundle in the sintered body is preferably 4-60vol.%. The carbon fiber bundle is oriented in over one dimension in the matrix. The carbon fiber bundle is covered with a middle layer of SiC, TiN or the like on the surface to prevent from damage by the reaction with the matrix component. The sintered body is coated with an oxide such as SiO2, TiO2, ZnO2 on the surface to chemically stabilize in an application environment.

Title: Generating circuit for staff synchronizing clock
Inventor: EKOSHI HIROYA
IPC: H04L7/00
Filed: 1985-11-29
Abstract: PURPOSE:To prevent the occurrence of errors even in case the writing data has jitter by producing a thinned out state at a staff bit inserting position through a staff bit inhibiting circuit when the phase difference of output exceeds a prescribed level between a counter and a writing counter. CONSTITUTION:A reading clock generating circuit 6 produces a reading clock having a thinned out state at the inserting position for service bit. The output of the circuit 6 is smoothed by a PLL circuit 9 and this smoothing output is supplied to a counter 7 via a staff bit inhibiting circuit 8. A phase comparator 4 compares the output of the counter 7 with the output of a writing counter 1. The first phase of the output of the counter 7 is coincident with the center point (g) of the data phase. Here the shift width from the point (g) is equal to 1/2 shift width of phase caused by insertion of a staff bit. Therefore the threshold value of insertion of the staff bit is approximately equal to a point (f). Then the output of the counter 7 is compared with that of the counter 1 and a staffing action is carried out when the phase difference between the outputs of both counters 7 and 1 exceeds the threshold value point (f).

Title: Mixer circuit
Inventor: TAKAHASHI KENICHI
IPC: H03D7/02
Filed: 1987-10-23
Abstract: PURPOSE:To improve the noninverting and inverting balance of a balancing/ unbalancing terminal by providing a balancing/unbalancing converter using a ferrite core and a metallic plate or rod from the grounding face or its vicinity so as to make the metal in contact with the ferrite core. CONSTITUTION:The metallic plate 8 provided from the ground face is made in contact with a ferrite core 1A with respect to a balun 1 using the ferrite core 1A. The metallic plate 8 reduces spurious radiation from the ferrite core 1A to control the potential on the ferrite surface thereby improving the balance between balance terminals 1b and 1c. The balance is improved resulting in improving a 2nd order cross modulation distortion thereby adjusting the inverting and noninverting balance. The effect is eminent.

Title: Door structure for storage
Inventor: NISHIMURA TAKASHI
IPC: F25D25/00
Filed: 1995-10-18
Abstract: PROBLEM TO BE SOLVED: To eliminate the worsening of appearance simply otherwise caused by a gap which may permits deviation of a slide-out door. SOLUTION: An upper cap 41b corresponding to the top surface of a lower side slide-out door 34 is inclined downward from the front end part to the rear end part so that the inside of a gap 65 gives a gap dimension C equivalent to a combination of a deviation distance of a lower side slide-out door 34 and an allowance dimension B and the outside of the gap 65 gives a gap dimension B equivalent to the allowance dimension B narrower than the inside thereof.

Abstract: PURPOSE:To change a specific information as necessary by providing a means identifying specific information to be changeable and unchangeable information and changing the changeable specific information. CONSTITUTION:In an IC card 1, a CPU 4 collates an inputted pass word as to whether it is coincident with the pass word stored in a prescribed area of an EEPROM 5 or not. When the collation is applied, a change instruction data is brought into a receptional state and when a change instruction data is inputted, the CPU 4 uses an index data included in the instruction data to seek the coincident index data from the EEPROM 5. When the data is found out, the CPU 4 references the identification information corresponding to the index data to confirm whether or not the corresponding specific information is changeable and when the information is changeable, the revision data included in the instruction data is stored to output a reply data signifying the end of revision externally. Thus, the specific information is changed as necessary.

Title: Electrophotographic sensitive body
Inventor: KASAHARA MASAHIKO
IPC: G03G5/08
Filed: 1987-10-26
Abstract: PURPOSE:To improve surface charge retentivity and fatigue resistance characteristics by forming an electron injection restraining layer large in a band gap between an electric charge generating layer and a surface protective layer. CONSTITUTION:The electrophotographic sensitive body is formed by laminating on a conductive substrate 1 a charge transfer layer 2 and the charge generating layer 3, and moreover, the electron injection restraining layer 4 and the surface protective layer 5. The layer 4 is made of pure Se or an Se-As alloy containing <=10wt.% As and it is preferred to have a layer thickness of <=10mum. The interposition of the layer 4 of such a composition restrains transfer of electrons generated in the layer 3 to the layer 5 and prevents drop of the surface potential. The control of the layer thickness of the layer 4 to <=10mum improves sensitivity, thus permitting surface charge retentivity and fatigue resistance characteristics to be improved.

Title: Pair data detecting circuit
Inventor: KONYA MINEHIRO
IPC: G06F15/82
Filed: 1988-10-26
Abstract: PURPOSE:To quickly perform the sure synchronous processing to increase the operation speed by outputting a synchronizing instruction signal to a data field OR part at the time when the instruction field of an inputted packet indicates a synchronizing instruction. CONSTITUTION:An instruction discriminating part 8a discriminates whether an instruction field 17 of the packet inputted from an input port A through a memory read part 2a indicates the synchronizing instruction (SYNC) or not. When the part 8a discriminates that it indicates the synchronizing instruction, the output of a normal instruction signal A to a data processing part 4a is stopped to stop the normal processing, and a synchronizing instruction signal A to a data field OR part 9a is outputted. When the part 8a discriminates that the instruction field 17 does not indicate the synchronizing instruction, output of the synchronizing instruction signal A is stopped, and the normal instruction signal A is outputted to the data processing part 4a to continue the same normal processing as a conventional example. Thus, the sure synchronous processing is performed considerably quickly in comparison with the conventional example to greatly contribute to increase of the operation speed.
