Title: Clock extracting circuit
Inventor: SHIMIZU HIROSHI
IPC: H04L7/02
Filed: 1980-12-17
Abstract: PURPOSE:To obtain a light-weight, small-size, and nonadjusting clock extracting circuit, by storing a maximum position detection signal of a return-to-zero single current digital code in a counter, which counts local clocks of a high frequency, to divide the frequency of local clocks. CONSTITUTION:A return-to-zero single current digital code S4 is inputted to a maximum position detecting circuit 1; and when a pulse of the code S4 becomes maximum, a detection signal S5 is transmitted to a storage terminal LD of a counting circuit 3. Local clocks S6 from a local clock generator 2 which generates clocks of an about 8-fold frequency of the clock frequency of the code S4 are inputted to the circuit 3 from a terminal CP and are counted; and when the signal S5 is applied to the circuit 3, the circuit 3 stored 1,0, and 0 from data input terminals D2, D1, and D0. That is, the phase of the circuit 3 is corrected at every maximum point of pulses of the code S4. Consequently, clocks S7 are extracted from an 8 frequency division output Q2 of the circuit 3 and are outputted.

Inventor: MURATA KAZUSHIGE
IPC: B28B1/26
Filed: 1989-07-11
Abstract: PURPOSE:To mold a molding having an opening readily and efficiently by attaching a flexible material to the opening forming part, and making the flexible material close-adhere to another molding mold or the flexible material which is attached to the other molding mold, and then supplying slurry therebetween. CONSTITUTION:An upper mold 1 and lower mold 2 attached with a flexible material 4 are mold-matched so as to be faced to each other via a molding space, wherein the flexible material is made to close-adhere to the lower mold 2. The flexible material 4 is expanded in its diameter such that the protrusion 4b is compressed in the axial direction through the elasticity. A slurry 3 is cast therebetween and the molding space is filled with a padding material 5, and then the upper mold 1 and lower mold 2 are separated from each other. Inasmuch as the flexible material 4 is released in its compressive force, the protrusion 4b is contracted in its diameter and restored to the original configuration, at that time, a gap 6 is formed between a padding 5 molded in the diameter expansion of the protrusion 4b and the protrusion 4b in the diameter contraction. For this reason, the flexible material 4 and padding 5 are separated automatically, thereby demolding the padding 5 readily.

This amt. is sufficient to form a protective cover on protrusions C and D with those protrusions A and B exposed after drying and hardening this layer. The solvent is removed for starting the hardening and relaxation of the layer 11, and this causes the layer to be cut open on the protrusions A and B and these parts from being pulled toward the vol. part of the layer 11, as shown by the arrow mark. As the result, the structure has a surface 12a at specified vertical level. The thickness ts of the dried and hardened layer covering the protrusions C is sufficiently large to protect the protrusions C after their subsequent processing.
