Title: Semiconductor device
Inventor: AKEYOSHI TOMOYUKI
IPC: H01L29/68
Filed: 1993-11-01
Abstract: PURPOSE:To precisely give weight to individual gate electrodes for a semiconductor device by a method wherein an input gate electrode is constituted of an aggregate of gate electrodes having a weight of one. CONSTITUTION:A plurality of gate electrodes 25 whose fundamental unit has a weight of one in terms of an electrode width W1 as a reference are arranged side by side by keeping an interval at the right end and the left end of an emitter electrode 11 in such a way that respective depletion-layer regions 9 are not overlapped. Then, an input gate electrode is formed by electrically connecting the gate electrodes of the number corresponding to weight in parts where a change in the depletion-layer regions 9 does not cause any problem. Since the input gate electrode is constituted as an aggregate of the gate electrodes 25 whose fundamental unit has a weight of one in this manner, all the gate electrodes 25 include the same spread of the depletion-layer regions 9 in edge parts. As a result, it is possible to obtain the precise weight of a mutual conductance.

Filed: 1992-11-02
Abstract: PURPOSE:To suppress the transmission of undecided data until the writing of data from a CPU in an overhead(OH) memory is ended at the time of a reset or the power supply of a device, in the value of the specific OH data of an STM data. CONSTITUTION:At the time of the reset, a reset signal detecting circuit 110 transmits a detection signal to a select signal generating circuit 107, and at the time of the power supply of this device, a power supply detecting circuit 110 transmits the detection signal to the select signal generating circuit 107. And also, when a CPU 106 ends the writing of the data in an OH memory 102, a writing end detecting circuit 120 transmits the detection signal to the select signal generating circuit 107. The select signal generating circuit 107 switches a selector 103 by those detection signals, and while the value of OH data (d) 116 are undecided, an initial value 117 of the OH data prepared by an OH data initial value preparing circuit 121 is transmitted instead.

IPC: H03H9/25
Filed: 1997-10-28
Abstract: PROBLEM TO BE SOLVED: To provide a thin piezoelectric element which has high frequency and can secure its stable temperature characteristic as designed by laminating two types of piezoelectric ceramics having positive and negative temperature change rates respectively in regard to the traveling velocity of an elastic wave. SOLUTION: The piezoelectric ceramics A having the positive temperature change rates of elastic wave traveling velocities and the piezoelectric ceramics B having the negative temperature change rates of elastic wave traveling velocities are periodically laminated together. That is, the ceramic material powder is burnt and crushed and then mixed into a 2-propanol solvent. These material powders are laminated into a sheet form. In such cases, a composition A contains Pb(Mg1/3 Nb2/3 )0.125 Ti0.435 Zr0.44 O3 and a composition B contains Pb(Mg1/3 Nb2/3 )0.375 Ti0.375 Zr0.25 O3 . Then the layers 1 of 50 μm containing composition A and the layers 2 of 20 μm containing composition B are periodically laminated together. This lamination structure of layers 1 and 2 is heated in the air at 700 deg.C and for 5 hours and then burnt in an oxygenic atmosphere at 950 deg.C and for 5 hours.  Then a copper elastic wave exciting electrode 3 and an elastic wave receiving electrode 4 are baked onto the lamination structure to complete the treatment. As a result, the center frequency change rate is reduced and the temperature characteristic is stabilized.

IPC: G06F1/32
Filed: 1995-11-14
Abstract: PROBLEM TO BE SOLVED: To provide an optimum multi-processor constitution for a portable computer in which a battery operation is required. SOLUTION: A parallel degree switch part 16 controls the operation/operation stop of four CPUs 11-14. The type of a power supply source, a calorific value, the load of CPU in the middle of an operation, or the number of CPUs which are simultaneously operated in accordance with operation environment setting by a user or system software, namely, CPU parallel degree is set. When power is supplied from an AC power source or when the highest performance of the computer is required, power consumption increases by setting the parallel degree to be high, but, processing performance can be improved.

Due to this reaction, power in a prescribed direction is generated and the carriage 115 rises to the surface. At this time, if ice is stuck to each five running roller 135, 137, etc., it is peeled off and destroyed. In particular, ice interposing between the water surface running roller 137 and the lower rail 120 is completely peeled off.

Title: Manufacture of light guide plate by using sandwich molding method
Inventor: KOIKE YASUHIRO
IPC: G02F1/1335
Filed: 1995-10-20
Abstract: PROBLEM TO BE SOLVED: To manufacture a light guide plate provided with an area having a relatively high scattering power and an area having a relatively low scattering power in a simple process by using the sandwich molding method and manufacturing the light guide plate of light scattering light guide type. SOLUTION: The injection of a material B for a skin layer only is carried out to fill the whole of a cavity. The injection of the material B is carried out in the final stage, by which the necessary process is started in the state of leaving the material B for the skin layer only on a nozzle end section of a molding machine. The formation of an unnecessary high scattering power area, therefore, is avoided in the initial stage of the following process by the arrangement. Unlike the two-color molding, the insert molding or the like, a material A for a core layer and the material B for the skin layer are injected. As the flows of both materials in the molten state are brought into contact with each other for a certain period of time, the material A is mixed with the material B on a boundary section.  Thus neither the boundary of a core layer and the skin layer gets excessively definite and sharp nor a discontinuous layer of refractive index is formed.

Title: Image forming device
Inventor: MIZUNO RYUKICHI
IPC: G03G15/02
Filed: 1999-10-19
Abstract: PROBLEM TO BE SOLVED: To surely recover foreign matter attached to an electrifying member and to suppress the scattering of the foreign matter that is attached and accumulated to a cleaning member. SOLUTION: Relating to the device, the potential of each of the cleaning member 11, the electrifying member 9 and a photoreceptor are set so that the potential of the cleaning member 11 > potential of the electrifying member 10 > potential of a photoreceptor 2 during a cleaning operation of a electrifying device 3 by the cleaning member 11. Thus, the foreign matter that has the same potential as the cleaning member 11 that is eliminated from the electrifying member 10 and attached and accumulated to the cleaning member 11 is effectively shifted to the photoreceptor 2 and recovered. As a result, since the scattering of the foreign matter from the cleaning member is prevented during the cleaning operation, soiling inside the image forming device due to scattering of the foreign matter is prevented.
