Patent JP-H01162387-A (JP)
Title: Rubidium atom oscillator
Inventor: NAKAJIMA YOSHIBUMI
IPC: H01S1/00
Filed: 1987-12-19
Abstract: PURPOSE:To improve an oscillating frequency in stability by a method wherein a prism is provided onto a projecting optical axis of a lamp cell, and the excitation light of metallic rubidium is separated from the excitation light of a buffer solution so as to enable only the excitation light of rubidium to be incident on a photodetector. CONSTITUTION:The Rb excitation light projected from a lamp cell and the Ar excitation light emitted through a buffer solution penetrate a resonance cell 11 travelling through the same optical path and a transmitted mixed light 16 is made to be incident on a prism 12. As Rb excitation light is infrared rays and the Ar excitation light is visible rays, the mixed light 16 is separated into a Rb excitation light 14 and an Ar excitation light 15 through the prism 12 and projected out from the prism 12, therefore, only the Rb excitation light 14 can be caught very efficiently by providing a photodetector 13 such as a solar cell or the like to an adequate position. In result, a resonance peak signal can be improved in a S/N ratio.

Title: Communication equipment
Inventor: SAKAGUCHI KATSUHIKO
IPC: H01M10/48
Filed: 1989-12-11
Abstract: PURPOSE:To prevent communication error in the middle of communication, the loss of transmission/reception data and the run away of an electronic equipment itself, etc., by comparing energy required for executing the communication with remained energy at that time before starting the communication and limiting the execution of the communication or warning the execution when sufficient energy is not obtained. CONSTITUTION:A central processing unit (CPU) 5 receives a communication starting instruction from a user, obtains the current remained energy by a detector 3 and compares the energy, which is stored in an energy memory 2, required for the execution by reading, and when the remained energy is larger than the required energy, data are exchanged with a main memory 1 through a transmitter/receiver 4. When the remained energy is smaller than the required energy, such a state is informed of the user and the communication is not executed. Thus, there is no possibility for the communication error in the middle of communication, the loss of transmitting/receiving data, the run away of the electronic equipment itself, etc.

Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a semiconductor device which can increase the durability of a cutting equipment and increase yield by fixing a wafer firmly on a base, so that cut pieces of the wafer do not peeled off from the base. SOLUTION: When a wafer member 42 is attached to an adhesive tape by the entire rear face and thereby fixed on a stage 54, an exposed part of a rear face 39 of a semiconductor wafer 33 and an oxide film 28a left over on a part other than the exposed part of the wafer are attached to the adhesive tape 52.
