摘要： For applying ferroelectrics to electronic devices, the poling treatment of the ferroelectrics has been necessary in order to uniform directions of spontaneous polarizations, Ps, in each ferroelectric. This treatment brings about (1) low yields of the devices, (2) difficulties in the fabrication of array devices, and (3) difficulties in the formation of ferroelectric films on semiconductor devices. Now it has been found that a self-polarized film in which spontaneous polarizations, Ps, are unidirectional can be formed by sputtering a ferroelectric materials containing lead under such conditions that the orientation of Ps will be controlled without poling treatment and a high-performance ferroelectric device can be obtained in a high yield by using this film, and thus a process for producing such devices has been found.

摘要： A self-propelled fork lift truck comprises a working mechanism at the front end of the fork left truck, a revolving driver's stand, a driver's seat and a steering wheel mounted on the revolving driver's stand, a speed change gear having a plurality of speed shifting ratios for running in a forward direction and a plurality of speed shifting ratios for running in a backward direction, and a speed change gear controlling device. When the revolving driver's stand is turned facing the front end of the fork lift truck, the controlling device restricts the operation of the speed change gear to a first of the plurality of speed shifting ratios for running in the backward direction. When the revolving driver's stand is turned facing the rear end of the fork lift truck, the controlling device restricts the operation of the speed change gear to a first of the plurality of speed shifting ratios for running in the forward direction.

摘要： An environmental test apparatus comprising a substrate on which a test specimen is mounted securely, a cover disposed on the substrate for housing the test specimen within a tightly closed space thereof, a temperature/moisture adjusting system for adjusting temperature and moisture in the tightly closed space, a memory for storing control data such as accumulated past data or various kinds of environment reproduing data, a control system for controlling the temperature/moisture adjusting system based on the control data stored in the memory and a data measuring system for measuring and recording various kind of data for environmental test. Since the test specimen is disposed in the tightly closed space and temperature and moisture in the space are controlled based on the control data such as the past accumulated data or various kinds of environment reproducing data, test, for example, on transportation, storage or accumulation can be conducted with no actual experience of such an environment but under simulated environmental conditions relevant thereto, so that the effects of the environmental conditions on the cargos can be specified scientifically and accurately.
