Title: Phs system
Inventor: OGATA SHIGERU
IPC: H04W92/18
Filed: 1995-08-15
Abstract: PROBLEM TO BE SOLVED: To enable simultaneous waiting for inter-slave set direct communication at the time of a public mode or a private mode by providing a means for controlling a frequency and a timing by which a signal from another slave is received at a specified timing in the slave set. SOLUTION: The control part of the slave set controls the timing and the frequency of communication. In the radio wave signal a TDMA-TDD system, the timing and the frequency for receiving the signal from a master set on a time axis are different from those of inter-slave set communication. The timing 19 is the timing of the signal from the master set (public base station) like the timing 18. But the timing 20 for searching the calling signal from another slave set is received after that, so that the calling signal between the slave sets can be received even while waiting the signal from the master set. This searching timing 20 does not necessarily come after the timing 19 and it can exist at every decided time in the timing 19. The frequency is also controlled by the timing 20.

Title: Drawing of earth anchor
Inventor: YODA MASAMI
IPC: E02D5/80
Filed: 1981-12-24
Abstract: PURPOSE:To draw out a tension steel member with small loads by packing a static breaking agent is into a sleeve at the fixed portion of an anchor through an aperature formed when pulling out a core material. CONSTITUTION:A core material 11 is pulled out of sleeves 13 and 14, and a slurried static breaking agent 16 is packed into the sleeve 13 at the fixed portion A of an anchor through the aperture formed when pulling out the core material 11. The static breaking agent 16 used is composed of a lime-based inorganic compound as a main component and an organic and inorganic compound and exerts an expansion pressure as a breaking force from its hydration reaction. The cement mortar 4 of the fixed portion A of the anchor is broken by the expansion pressure of the static breaking agent 16 and thereby the adhesion between a tension steel member 12 and the cement mortar 4 is weakened. The  tension steel member 12 thus separated is drawn out with small loads, e.g., man  power, etc.

Title: Crystal oscillating circuit
Inventor: ISHIDA RIICHI
IPC: H03B5/32
Filed: 1988-08-24
Abstract: PURPOSE:To obtain the duty of 50% with a non-adjustment by making coincident the action point of all continuous inverters to the voltage value of 1/2 of the supply voltage of the inverters. CONSTITUTION:Only when an input voltage Vin is near an action point voltage Vt, the current flows at both Q1 and Q2 and the area becomes the action area of an inverter. When the size ratio of transistors Q1 and Q2 of respective steps is made equal and set to Vt=VDD (positive supply voltage value)/2, the output sine wave of an inverter 3 for oscillation becomes the waveform having upper and lower oscillation widths with Vt as a center. The input of an inverter 6 for waveform shaping is oscillated with the Vt as a center and the output becomes the rectangular wave to oscillate in upper and lower directions with the Vt as a center. Thus, regardless of the oscillation frequency and the waveform of a crystal oscillator, the rectangular wave pulse of the duty 50% can be obtained at an output point out.
