Patent JP-S64331-B2 (JP)
IPC: C01B33/152
Filed: 1982-12-23
Abstract: PURPOSE:To prevent cracking during preparation of gel and its sintering and to obtain an optically and mechanically homogeneous quartz glass by properly adjusting the pH of a raw material compsn. consisting of metal alkoxide ultrafine silica powder, etc. at the time of its feed. CONSTITUTION:The raw material compsn. consisting of metal alkoxide, ultrafine silica powder, water, acid, alcohol, etc. is exactly adjusted to 4-6pH at the time of its feed by adding aq. ammonia or the like alkali. This sol soln. is dried to form a gel and it is sintered to form quartz glass. This method strengthens the gel structure, and seldom causes cracking, though large contraction of the volume occurs at the time of formation of dry gel. Therefore, large dry gel can be formed. Since this dry gel seldom causes cracking during sintering, a large quartz glass plate can be formed.

Abstract: The present invention provides a matching circuit for connecting a chrominance decoding integrated circuit normally connected by terminals to a conventional analog delay line so as to make it compatible with a digital delay line. This matching circuit comprises a switch connecting alternately each of the outputs of the integrated circuit to an analog-digital convertor connected to a digital delay line, to a digital-analog convertor, then to a switch routing the signal alternately to each of the two summators whose other inputs receive directly the output of the integrated circuit. The summators supply then respectively the chrominance signals R-Y and B-Y.

Abstract: Printed articles are converted and conveyed with high performance by a method wherein the printed articles are organised in clusters (2, 2'). A cluster of printed articles is a group of at least two individual printed articles which are jointly processed in cluster streams over a partial section or in a partial process. Such a cluster stream can be divided or reduced to a cluster stream of lower magnitude (decreasing number of printed articles per cluster). It is also possible to mix or combine cluster streams. As a result, it becomes possible to provide a processing performance at the desired positions, within an overall system, which in principle has no upper limit. At the same time, the process permits increased flexibility by means of special buffer facilities, redundancy, etc, with relatively low expenditure of materials and costs.

Abstract: At the transmitter side, carrier waves are modulated according to an input signal for producing relevant signal points in a signal space diagram. The input signal is divided into, two, first and second, data streams. The signal points are divided into signal point groups to which data of the first data stream are assigned. Also, data of the second data stream are assigned to the signal points of each signal point group. A difference in the transmission error rate between first and second data streams is developed by shifting the signal points to other positions in the space diagram expressed at least in the polar coordinate system. At the receiver side, the first and/or second data streams can be reconstructed from a received signal. In TV broadcast service, a TV signal is divided by a transmitter into, low and high, frequency band components which are designated as a first and a second data streams respectively. Upon receiving the TV signal, a receiver can reproduce only the low frequency band component or both the low and high frequency band components, depending on its capability. Furthermore, a communication system based on an OFDM system is utilized for data transmission of a plurality of subchannels, wherein the subchannels are differentiated by changing the length of a guard time slot or a carrier wave interval of a symbol transmission time slot, or changing the transmission electric power of the carrier.

Abstract: A porous product, typically a metal foam sheet, is produced as a tailored, engineered product. The porous product can have enhanced strength, as well as more desirable electrical and mechanical properties. The product which first exists typically as a flexible, generally polymeric foam sheet in strip form, which strip is produced in the longitudinal direction, is stretched in a direction other than its direction of production. The porous product can have pores which would be anisotropic in form in usual production, which are stretched to at least substantially isotropic form. The product can even be tailored to have pores which are anisotropic in the direction of the stretch. Thus, an engineered product can be produced which, for example, as an open-cell metal foam prepared from a polymeric foam can have conductivity, both thermal and electrical, as well as strength and ductility, tailored for greater uniformity and performance.
