Title: Developing solution
Inventor: NAKAMURA HIROTO
IPC: G03G13/00
Filed: 1989-05-19
Abstract: PURPOSE:To enhance the adhesive strength of a toner on a transfer medium by forming the insulating solvent in a developing soln. of a thermoplastic material. CONSTITUTION:The thermoplastic material 12 is used in place of the insulating solvent. Namely, the developing soln. is liquid at ordinary temp. and is melted by heating to execute development at the time of the development. The transfer of a photoconductive toner 11, etc., are exactly identical to the transfer, etc., of ordinary developing methods in the case of executing the development by raising the temp. when the developing soln. is formed of the thermoplastic material 12 in such a manner. However, a state change arises in the solid when the thermoplastic material 12 is restored to the ordinary temp. in the case of using this developing soln. and, therefore, there is no need for a drying stage. Since the trace thermoplastic material 12 transferred to paper to be transferred has an adhesive effect, there is no need for the chemical and physical fixing to enhance the adhesiveness of the toner 11 and the paper to be transferred.

Title: Diffuser
Inventor: HORIKAWA YOSHIAKI
IPC: G21K1/10
Filed: 1993-05-27
Abstract: PURPOSE:To obtain a transmission type diffuser which can transmit and diffuse even a light having short wavelength by forming microparticles having a specific particle size on a thin film transmitting soft X-rays. CONSTITUTION:Light beam from a high output pulse laser 1 is condensed through a condenser lens 2 and projected onto a target 5 placed in a high vacuum container 4 through an incident window 3 thus generating soft X-rays 6. The soft X-rays pass through a rotary elliptical oblique incident condenser mirror 7 and impinge on a diffuser 8 where the X-rays are diffused. The X-rays then pass through a thin film window 10 and impinge on a sample 12. Subsequently, the X-rays transmit through a thin film window 11 and impinge on a Schwarzschild objective lens 13 to be focused on an image detector 14. The diffuser 14 is produced by forming microparticles having particle size 1-1000 times as large as the wavelength of soft X-rays on a thin film transmitting the soft X-rays. This constitution allows diffusion of light having short wavelength, which is absorbed by a conventional transmission type diffuser, in Mie scattering region where the loss of the quantity of light is low.

Title: P-channel insulated gate type bipolar transistor
Inventor: IWAMURO NORIYUKI
IPC: H01L29/739
Filed: 1989-05-19
Abstract: PURPOSE:To scarcely cause an avalanche breakdown at the time of turning OFF by regulating the grounded emitter current amplification factor of an npn bipolar transistor formed in a p-channel insulated gate type bipolar transistor IGBT to 8.0 or less. CONSTITUTION:A p-channel IGBT must continuously supply a predetermined current at the time of turning OFF an L load. Thus, an npn transistor is driven by holes extruded by a depletion layer extended to a p<->-type layer 3 at the time of OFF instead of holes supplied from a P-channel MOSFET at the time of ON. When the grounded emitter current amplification factor is suppressed to 8.0 or less, the electron current of the total current is reduced to suppress generation of avalanche carriers. Thus, an avalanche breakdown scarcely occurs.

Title: Diffusing method of impurity
Inventor: MATSUMOTO YOSHINARI
IPC: C30B31/06
Filed: 1977-10-19
Abstract: PURPOSE: To ensure good diffusion of the impurity by setting the quantity of the impurity element of the diffusion source to such amount that the vapor pressure of under the heat balanced vapor pressure at the coexisting time with only the diffused material at the diffusion temperature.  
     CONSTITUTION: Diffusion source 24 obtained by evaporating Zn-group 12 to non- added GaAs11 is put into quartz tube 21 of about 5ml capacity along with GaAs25 to perform the Zn diffusion at 566°C. The vapor pressure of Zn,Ga and As inside the tube is supplied mainly from Zn layer 12 in which Ga and As are fussed together. The Zn solution of Ga and As features a lower decomposition pressure than GaAs, so the heat balanced vapor voltage of Ga, As and Zn inside the tube is almost supplied from source 24 with no impairment of the surface of GaAs 25 through the Zn diffusion. The thickness of layer 12 is set to 10μm or less, the fusing velocity is increased for Ga and As, and the quantity of the diffusion source is set so that the vapor pressure of under the saturation vapor pressure of pure Zn may be obtained at 566°C for the total Zn amount in layer 12. With this method, the impurity diffusion becomes possible over a wide range of density with a sufficient diffusion depth and good density regeneration performance

IPC: H04M1/00
Filed: 1986-05-30
Abstract: PURPOSE:To enable a called subscriber to receive surely the telephone messages by recording the messages so far received until a time point reception os the transferred massages is not estimated such as the called subscriber does not reach the plase where the messages to be transferred, then transmitting th messages so far received by a telephone set at a time point when the messages can be received. CONSTITUTION:A transfer telephone equipment can transfer the messages received from calling subscribers while the called subscriber is absent to the prescribed message transfer destination. For instance, a time point when the called subscriber may reach the message transfer destination is previously set when the called subscriber is going to said transfer destination. Thus the automatic dial means 1 and 5 are kept inactive until said time point set previously. The messages received from calling subscribers while the means 1 and 5 are kept inactive are not transferred and recorded. Then both means 1 and 5 are active at said time point and therefore the recorded messages are transferred. Thus the called subscriber can receive those messages without fail.
