Patent JP-H04181916-A (JP)
Title: Directional coupler type semiconductor optical switch
Inventor: HAMAMOTO KIICHI
IPC: G02F1/025
Filed: 1990-11-16
Abstract: PURPOSE:To evade propagation loss caused by absorption loss by inserting a 1st undoped clad layer under a guide layer. CONSTITUTION:By inserting the 1st undoped clad layer 3 shown by an hatched part not only in an undoped guide layer 4 or a 2nd undoped clad layer 5 which is inserted for the use of the electric separation of an element but also between an n type 1st clad layer 2 and an undoped guide layer 4, the absorption loss caused by the free carrier absorption of guided light hardly occurs. Since the light is mostly kept in the undoped layer, there is no possibility that switching voltage becomes high even in the case of inserting the layer 3.

Title: Concealed information card
Inventor: NIIMI NORIAKI
IPC: B42D15/02
Filed: 1998-11-02
Abstract: PROBLEM TO BE SOLVED: To provide a concealed information card which has effective design properties giving an impact to a card receiver through the addition of a high design effect to a concealed information display part, when the card receiver side checks the details of the concealed information display part. SOLUTION: An information concealing seal 40 is constituted of a first film layer made of a hologram film 30 and a second film layer bonded as a simulated layer on the first film layer in a freely peelable manner. When both first and second film layers are separated by peeling from each other at an interface (a pseudo adhesive face) between these layers, the hologram film 30 is exposed on the peeled faces to make a hologram appear, and through the hologram film 30, the display contents (printed or written personal information, confidential information and design pattern) of the concealed information display part of a postcard form 20 are visibly recognized. Thus a high design effects is realized by a hologram interference band.

Title: Production of resin comosition for toner
Inventor: KOSAKA YOSHIYUKI
IPC: G03G9/087
Filed: 1993-12-13
Abstract: PURPOSE:To produce the resin composition having low residual monomer and residual solvent concn. in it and excellent performance required as a resin composition for the toner by supplying a resin solution, in which a high molecular weight polymer component and a low molecular weight polymer component are dissolved, to volatile matter removing devices placed in series. CONSTITUTION:In this production, the resin used as the starting material consists of a high molecular weight polymer component and a low molecular weight polymer component and is dissolved into an organic solvent to obtain a resin solution and thereafter, the resin solution is supplied to the first stage volatile matter removing device 3, that is heated and evacuated, to concentrate the solution and then the concentrated solution is supplied to the second stage volatile matter removing device 4 to reconcentrate it. Since the resin solution, in which the binder resin component of the resin composition for the toner is dissolved, is twice subjected to volatile matter removing treatment, the resin solution can be concentrated so as to attain low concn. levels of the residual monomer and the residual solvent in it. Further, since the volatile matter removing capacities of the devices 3 and 4 are sufficient even at the time of keeping the temp. low, the heating temp. can be lowered. Accordingly, the breakdown of the high molecular weight polymer molecule due to the thermal decomposition can be inhibited from occurring.

Title: Portable terminal equipment
Inventor: URUSHIMA TETSUO
IPC: G06F1/32
Filed: 1988-12-14
Abstract: PURPOSE:To lower the power source capacity and reduce weight by utilizing a free time of key input data and switching an oscillation frequency. CONSTITUTION:Various peripheral equipments 5-10 connected to a control circuit 3 are operated by a control of the control circuit 3. The control circuit 3 is almost operated by inputting data from a key, and since its data is operated by a man, the input time is very slow. Also, in many cases, some other work is executed after inputting the data, and the input is executed again, and in this case, an interval is generated for inputting the data. When this interval is generated, an oscillation frequency is lowered by a switching circuit 5, by which a voltage consumption is suppressed. In such a way, by lowering the oscillation frequency to 1/2, the power consumption can be lowered to <= about 1/3, comparing with the conventional power consumption.

Inventor: SAITO KENJI
IPC: B23K11/04
Filed: 1988-12-14
Abstract: PURPOSE:To prevent the generation of thermal strain or deformation and residual stress by reducing gradually a load current to metallic material with the time. CONSTITUTION:Work holders 6 and 6 to hold horizontally the head side 4a and the shaft side 4b of an engine valve 4 via a couple of electrodes 5 and 5 are fitted in opposition each other on respective plates 2 and 3 of a flush butt welding machine W at the time of manufacturing a valve welded shaft. A triode AC switch 12 is a control rectifying device of a bothway 3 terminal connected to a primary coil 10 of a transformer 8. Firing time control (phase control) by the triode AC switch 12 is carried out based on time information sent to a firing angle control circuit 13 from a program timer 14. When the firing time is subjected to lag angle control by stages with the time, the load current flowing to electrodes (engine valve) 5 is reduced by stages. After welding is completed, a temperature drop and cooling is proceeded a slowly. By this method, the same effect as annealing takes place and deformation, etc., are prevented and a product with high finishing accuracy is obtained.
