Filed: 1982-07-29
Abstract: PURPOSE:To enable efficiently oscillate a semiconductor laser in a sable single lateral mode in the operation of high reliability and high output by forming an active layer in a plural multilayer strcture. CONSTITUTION:An N type InP clad layer 2, an active layer 3, a P type InP clad layer 4, an N type InP clad layer 5, an active layer 6, a P type InP clad layer 7, an N type InP clad layer 8, an active layer 9, and a P type InP clad layer 10 are sequentially formed on a semi-insulating InP substrate 1. An N type InP buried clad layer 11 and a P type InP buried layer are formed through etching steps in the course, thereby forming N type side electrodes 13 and P type side electrodes 14. These layers 2, 4, 5, 7, 8, 10 have relatively large forbidden band width. In this structure, when positive and negative voltages are applied to the electrodes 14, 13, the junction of a current to the layers 3, 6, 9 is performed. In this structure, since the active layers are completely buried in the clad layer, the carrier enclosing effect is excellent, and efficient oscillaction can be performed.

IPC: C02F1/06
Filed: 1979-10-15
Abstract: PURPOSE: To effect the purification of seawater with a good thermal efficiency in a process of brine purification using a multistage flush evaporator by a method wherein part of concentrated brine is discharged and the remaining part is cooled with a low temperature fluid and then guided to condensation pipe bundle.  
     CONSTITUTION: The brine is repeated with a sequential flush evaporation in each of the evaporation chambers 2aW2f and is flowed as concentrated brine from the last stage evaporation chamber 2f. The concentrated brine is cooled in a cooler 8 which uses a low-temperature fluid such as LNG or the like guided through pipe 17. The cooled concentrated brine is flowed through condensing pipe bundle 5fW5a, and the brine is heated with a brine heater 9, then circulated through each of the evaporation chambers. At this time, the stock seawater is deaerated by a deaerator 14 and supplied through a distributor 15 to the evaporation chambers having nearly the same temperature as the seawater. At the same time, part of the concentrated brine is discharged from pipe 11 so that a constant concentration is maintained. In this manner, the concentrated brine is circulated to minimize the amount of seawater used, and the production of noncondesable gas in the seawater is reduced. This enhances heat efficiency.

Title: Production of pressure-sensitive adhesive tape
Inventor: SHIMIZU IKUSUKE
IPC: C09J201/00
Filed: 1997-05-23
Abstract: PROBLEM TO BE SOLVED: To provide a tape which is excellent in adhesiveness at a low temperature and in releasing properties, due to bubbles formed and practically maintained in the adhesive layer of the tape (cohesive strength does not increase), by foaming the adhesive layer on one side of a tape substrate to thereby cause air bubbles to be present in the adhesive layer and taking the tape up in a roll form with a specific take-up tensile force. SOLUTION: An exemplified procedure is as follows. A volatile liquid such as water is coated on and impregnated into one side of a tape substrate. A pressure sensitive adhesive is coated on the substrate and then the substrate is heated to thereby foam the adhesive and cause air bubbles to be present in the adhesive layer. The tape is taken up in a roll form with a take-up tensile force of 0.3 to 7 kg/10 cm. This results in contacting the adhesive layer uniformly and intimately with the substrate and also in stretching the tape in the direction of taking up. When the stretched tape shrinks with the passage of time, the power of shrinkage is relaxed over the whole of the roll, so that, some of the bubbles are vanished, but some bubbles become increased in size. Accordingly, the disappearance of the bubbles in the adhesive layer is suppressed.

Title: Motor position controller
Inventor: KONNO MASANORI
IPC: G05D3/00
Filed: 1986-06-11
Abstract: PURPOSE:To inhibit the extreme position control even though the abnormal feedback signal is produced by the external noises and to ensure the smooth position control of a motor, by newly estimating the feedback signal and applying it to a feedback control means when the feedback signal value exceeds the control value. CONSTITUTION:A CPU 1 reads the resolver signal via a position detecting control circuit 15 and updates the feedback position. Here the feedback position signal is temporarily defined as FBnew since a circuit malfunction may possibly be considered. Then the difference DELTAnew is obtained between the feedback position FB read in the previous time and the feedback position FBnew read this time. Then a feedback error is decided if the difference DELTAnew is not kept between control values DELTA1 and DELTA2. Thus the FBnew is obtained as the correct value from the value FB read in the previous time and the difference DELTA between the previous FB and its preceding FB. It is decided that the correct position is read, if no feedback error is detected. Therefore the difference DELTA is replaced for the next reading action. In such a way, the position of a motor is controlled based on said feedback position FB.

Abstract: PURPOSE:To shorten the time needed by the designer of a custom LSI for verification by a method wherein a megacell is provided with a means for generating an output signal for verification different from the intrinsic function of the megacell and the output signal is controlled. CONSTITUTION:Necessary pattern data is previously written in a pattern ROM 106 in a megacell 101a and this data is outputted at the time of verification of a system.

Thereby, three-state buffers 203a and 204a are turned-OFF and the ROM 106 is brought into an operable state. In this state, an address, in which a necessary pattern is stored from an address signal MAa, is inputted from the outside and a readout signal RDa is inputted, whereby necessary output 5 is outputted from patterns P1a and P2a. By verifying the result of the output 5a, whether the connection between the megacell and a first U macro 102a is correct or not is decided.
