Title: Production of piezoelectric module element
Inventor: ICHIKAWA HIROSHI
IPC: H03H3/08
Filed: 1997-10-28
Abstract: PROBLEM TO BE SOLVED: To measure the working frequency of a piezoelectric module element while measuring it by irradiating an energy beam such as an ion, etc., on the element to partly scrape off its surface. SOLUTION: The working frequency of a piezoelectric ceramic filter is adversely proportional to its thickness. In this respect, the working frequency of a piezoelectric element is changed by scraping off the piezoelectric part of the completed element in its thickness direction. Thus, Al is evaporated on a piezoelectric substrate 1 by sputtering to form an elastic wave generating electrode 2 and a receiving electrode 3. Then the surface of the piezoelectric filter is etched by an argon beam 4 in a prescribed vacuum atmosphere. The center frequency of the piezoelectric filter is measured by constructing an amplifier and a resonator and then measuring the frequency of a resonating radio wave by means of a frequency measuring instrument. Thus, etching the surface of the substrate 1 can change the center frequency of the piezoelectric filter into a desired level.

Title: Electronic still camera with liquid crystal display function
Inventor: TOYODA TOSHIYUKI
IPC: G03B17/02
Filed: 1997-10-28
Abstract: PROBLEM TO BE SOLVED: To suppress the power consumption by an easy method by controlling the quantity of light emission of a back light to previously set luminance during the operation of an operation button. SOLUTION: While the operation button is operated, the quantity of light emission of the back light is controlled to the previously set luminance. For example, sensors 7a and 7b count the time, from when a photographer operates an adjustment input button 8 of an adjusting device for the 1st time so as to change photographic conditions to when the photographer operates the adjustment input button 9 next. When a timer 6 shows that the counted time is shorter than a time set previously in the camera, it is judged on the camera side that 'the photographer is setting the photographic conditions at present' and an instruction for decreasing the quantity of light of the back light is sent out. When the previously set time is elapsed after the last input, the camera side judges that 'the photographer has completed the photographic condition setting'.

Title: Information processor containing buffer memory
Inventor: MAEKAWA KAZUHIKO
IPC: G06F15/177
Filed: 1986-12-10
Abstract: PURPOSE:To secure the high-speed performance of a multi-processor system consisting of processors of different performances and functions, by comparing the address read out of an address array with the contents of a boundary address holding means and invalidating a buffer memory. CONSTITUTION:When an invalidation request is produced, the contents of a boundary address register 3 are stored in an address data register 10 via an address data selecting circuit 11. At the same time, an address selecting circuit 9 selects an address which receives successively addition of +1 by an address updating circuit 5 for updating of the contents of an address register 4. When the address value read out of a buffer memory address array 1 based on the contents of the register 4 is larger than the boundary address value of the register 10, a buffer memory invalidating circuit 7 is turned into an enable state via an address comparator 8. Then the corresponding entry is invalidated. Therefore a high-speed processor is not disturbed by a low-speed processor and the high-speed performance is never deteriorated for a multi-processor system consisting of processors of different performances and functions.

Abstract: PURPOSE:To obtain a highly reliable high-emission semiconductor laser element by a method wherein thermal resistance is designed to decrease to be within specified limits in the sides of a clad layer mesa or in a terrace flat arranged for heat radiation on the side opposite to a substrate. CONSTITUTION:On a GaAs substrate 1 with a mesa or terrace-type step provided on tis surface, a double heterostructure is built wherein an active layer 14 (AlxGa1-x)0.5In0.5P(0<=x<1) is sandwiched between two clad layers 13 and 15 (AlyGa1-y)0.5In0.5P(0<=y<=1). In a semiconductor laser element of this design, on the side opposite to the substrate 1, the thickness is reduced of a mesa or a terrace flat included in the clad layer 15 so that its thickness may be smaller than the electron Denibroy wavelength but no shorter than 0.2mum, which ensures a decreased in thermal resistance. In this way, a semiconductor light- emitting element may be obtained wherein the ordinary double heterostructure features are not at all affected in terms of the entrapment of light and carriers, a temperature rise is small in the activation layer, and the performance characteristics and reliability are improved.

Filed: 1998-10-16
Abstract: PROBLEM TO BE SOLVED: To map a foreign kind of logic elements in a part of electronic design compilation by using a required logic device to form two logic areas and comparing them and selecting one logic area based on the comparison result and adding it to the final mapping list. SOLUTION: First, a compiler takes the specification of a user as the input (S202). Next, electronic design is synthesized (S204), and functions of electronic design which can be executed on a programmable logic device are described. PTERM mapping (S206) and LUT mapping (S208) of electronic design are created in parallel. The compiler uses PTERM mapping to implement the electronic design in a form of logic areas like PTERM logic cones (S210). When electronic design is reduced to pairs of PTERM and LUT logic cones, a selection process (S214) selects highest one of each pair in accordance with a prescribed selection reference. The selected logic cone is used to form the final mapping (S216).

Title: Solvent applicator
Inventor: SANADA KAZUO
IPC: B06B1/06
Filed: 1997-10-28
Abstract: PROBLEM TO BE SOLVED: To obtain a solvent applicator of a low cost. SOLUTION: When water is not ejected, a command voltage of a high level is impressed on the respective bases of NPN type transistors(TRs) 412, 424 and the respective TRs are turned on. When the NPN type TR 412 is turned on, an FET 420 is turned off and, therefore, the impression of the voltage on a piezoelectric element 326 is not executed. At this time, the charges accumulated in the piezoelectric element 326 are discharged in an R1 direction. When, on the other hand, water is ejected, the command voltage of a low level is impressed on the respective bases of the NPN type TRs 412, 424 and the respective TRs are turned off. When the NPN type TR 414 is tuned off, the FET 420 is turned on and, therefore, a current flows from a reference power source 416 in an R2 direction and the prescribed voltage is applied on the piezoelectric element 326.  As a result, the displacement of the piezoelectric element 326 is made possible and the water may be gushed by this displacement.
