Patent JP-H01218085-A (JP)
Title: Semiconductor laser
Inventor: SHINOHARA YASUO
IPC: H01S5/00
Filed: 1988-02-26
Abstract: PURPOSE:To prevent occurrence of each unskillful p-n junction which is formed at a base of double channel parts and avoid leakage of an electric current, by making an n-type buffer layer grow thinly before forming a p-n-p current block layer in the process of a liquid phase epitaxy. CONSTITUTION:A multilayer structure consisting of an n-type buffer layer 2, an active layer 3, and a p-type clad layer 4 is formed by a liquid phase combined growth process on an n-type InP substrate 1. Then, two parallel grooves 5 (double channels) are formed in the multilayer by a photoresist process. After that, a p-n-p current block layer 6 as well as a cap layer 7 where the double channels are embedded grows by the second liquid phase epitaxy. In such a case, the current block layer 6 grows and its growth permits the n-type buffer layer 8 to grow thinly at the base of the double channels 5 before forming each p-n junction at the base of the channels 5. Thus, a semiconductor laser which is superior in characteristics is formed in such a way that no current leaks very much.

IPC: B41M5/382
Filed: 1986-03-04
Abstract: PURPOSE:To obtain the titled material in which a heat-resistant layer has low tackiness and which is less liable to contaminate a head, by forming the heat- resistant layer from a film-forming resin modified with a modifier which is a reaction product of a silicone compound having a reactive organic functional group with an organic polyisocyanate and has at least one free isocyanate group. CONSTITUTION:A thermal recording layer is provided on one side of a base sheet, and a heat-resistant layer is provided on the other side. The heat-resistant layer is provided by using a film-forming resin modified with a modifier which is a reaction product of a silicone compound having a reactive organic functional group with an organic polyisocyanate and has at least one free isocyanate group.

Title: Weighing device
Inventor: TOMOMORI MASATAKA
IPC: G01G19/40
Filed: 1990-02-28
Abstract: PURPOSE:To prevent weighing operation from being interrupted by providing a battery and a weight display unit to a scale part provided independently of a weighing device main body, and switching the power source to the battery by a power source switching means in the case of a power failure and displaying a weighed value on the display unit. CONSTITUTION:The weighing device main body 1 receives commercial electric power from a power source plug 4 and supplies it to the scale part 5 through a cord 7. When the scale part 5 weighs postal matter, its weight data is sent to the main body 1 through a signal line 7 to calculate the postal charge, which is displayed on an operator display unit 3 and a customer display unit 8. If the commercial power supply enters a failure state, the changeover switch of the scale part 5 is operated to switch the working power source to the battery and then the weighing operation is carried on, so that weight data are displayed on a liquid crystal display plate 6. Consequently, even if the power supply is interrupted, the weighing operation is carried out in scale part units and the result is displayed, thereby preventing the weighing operation from being interrupted.

Abstract: In a method and apparatus for the electronic measurement of the electricity used by a load, a rectified voltage signal proportional to the load voltage is generated, and a frequency modulated pulse train is generated in response to this rectified voltage signal, with the frequency of the pulses being proportional to the instantaneous amplitude of the rectified voltage. A load current signal is generated that is proportional to the load current and is gated during each pulse of the frequency modulated pulse train to generate a signal representing the product of the instantaneous load voltage and the instantaneous load current. This signal may be integrated over time to generate a signal representing the amount of electric energy used by the load.
