IPC: C04B37/00
Filed: 1987-09-16
Abstract: PURPOSE:To produce a member having intricate shapes which cannot heretofore be produced by integral molding as a homogeneous structural material which does not crack and break by tentatively adhering SiC-base moldings to each other by an adhesive agent consisting of SiC and binder, then calcining the molding to impregnate Si into the sintered body.

After the joint faces of two pieces of such worked moldings are ultrasonically cleaned in, for example, water, the moldings are tentatively adhered by using the adhesive agent consisting of the SiC powder and binder having the same grain size distribution as the grain size distribution of the moldings. The moldings and the joint parts are then calcined simultaneously at 2,000-2,300 deg.C, by which the moldings are joined and the Si is impregnated into the sintered body. The sintered body is thus homogenized and the homogeneous structural material is obtd.

Title: Comparator circuit
Inventor: WAKABAYASHI SHUNJI
IPC: H03K5/13
Filed: 1989-09-04
Abstract: PURPOSE:To prevent jitter from being generated and to enable comparison with high accuracy by sharp raising a capacitor potential while setting the level of a comparator at L when the output voltage of a capacitor reaches a threshold value, and instantaneously raising a comparing waveform to a second comparator. CONSTITUTION:When a pulse signal (a) is made L, a transistor(TR) 1 is turned off and a capacitor 3 is charged. When a charging voltage (b) reaches a threshold value (e), an output (f) of a comparator 10 is made L and TR 14 and 15 are turned off. Then, a collector potential instantaneously rises to a value close to a direct current power source DC and this is impressed to the capacitor 3. Afterwards, the voltage (b) also instantaneously rises up to the potential of the power source DC and as the compared result of a comparator 4, an output (c) rises instantaneously. Samely, when the signal (a) is made H, the output (c) also instantaneously falls. Then, since the waveform to instantaneously rise and fall is used, the jitter is prevented from being generated and the comparison is executed with the high accuracy.

Title: Shift control device for automatic transmission
Inventor: ISHIKAWA KAZUNORI
IPC: F16H59/18
Filed: 1988-09-16
Abstract: PURPOSE:To carry out shift-downs each at the optimum speed by operating a cut-off valve and an accumulator control valve in accordance with 4-3 kick down, manual down and coast down. CONSTITUTION:In the accumulator 67 of an over-drive direct clutch C-O, back pressure is controlled by a solenoid modulator valve 73 via a cut-off valve 75 and an accumulator control valve 72, on the back pressure side of the piston 83 thereof. The cut-off valve 75 discharges the oil on the back pressure side of the accumulator 67 in an accelerator-on condition, to delay the engagement of the clutch C-O at the time of carrying out 4-3 shift down. As the oil via the valve 72 is fed to the back pressure side of the accumulator 67 in an accelerator-off condition, i.e., at the time of carrying out 4-3 manual down, the engagement of the clutch C-O is accelerated. On the other hand, at the time of 4-3 coast down, oil pressure is fed from the valve 73 to the accumulator valve 72, which forcedly discharges the back pressure side oil of the accumulator 67, to delay the engagement of the clutch, reducing an engaging shock.

Title: Optical information recording and reproducing method
Inventor: ICHINOSE AKIRA
IPC: G11B20/10
Filed: 1983-12-06
Abstract: PURPOSE:To read a data of selector which is impossible to read by reading the data continuously from the sector whose former part of the address part is read properly when the address part of the selector is not read properly at the time of reading the data. CONSTITUTION:Since the sector address of some sector where data are written is not read properly, an output (a) of a sector address coincidence detection circuit 11 does not become the high level. When the data reading is not possible, the sector address which is intermediately before is set in a sector address register 9 by a CPU7 when the data are stored in the sector. A down counter 20 sets the data quantity in two sectors. When the data are not stored in the sector which is immediately before, the sector address is set in the same way, and the data quantity in one sector is set in the down counter 20. Thus, the sector data whose sector address cannot be read properly are obtained as the data in one sector which is read at the last.
