Title: Matching member and forming method thereof
Inventor: MAIKERU JIYON JIRU
IPC: H04R17/10
Filed: 1989-09-29
Abstract: PURPOSE: To extend the operation temperature range for precise resonance matching by using materials which have plural cavities (air holes) formed internally. CONSTITUTION: C-glass (soda-lime-borosilicate glass) is treated so as to be formed as a sponge structure body having cavities in a high proportion, thereby experimentally obtaining an acoustic impedance reduced to 3×10<5> . Glass foams are heated at a temperature where glass is converted in a mold and are formed into one by compression in a specific volume ratio, thus easily obtaining the super-light glass sponge structure body. A final piece 2 which can be applied to a PZT cylinder body 1 without further adjustment is produced by a proper mold. Obtained cavity materials don't actually show the change of the acoustic wavelength or the volume elastic modulus due to a temperature higher than the ambient temperature range.

Title: Discharge lamp lighting device
Inventor: KAKIYA TSUTOMU
IPC: H05B41/392
Filed: 1990-09-27
Abstract: PURPOSE:To control a power source frequency at a low cost and within a wide range so as to realize light dimming by adjusting a switching period of a switching element interposed between a base and an emitter of a bipolar transistor. CONSTITUTION:A pulse wave current of a constant period from an oscillation circuit 22 flows in a primary winding of a transformer 37 and a proportional current is generated in secondary windings 12 and 13. When a current flows in a secondary winding 35, this current flows into a gate of an FET 29 via a resistor 32 for making continuity so that a base and an emitter of a transistor Tr8 have equal electric potential to each other to make the Tr8 discontinuous. When the secondary winding is not electrified, the FET 29 becomes discontinuous. Consequently, a current generated in the secondary winding 12 of a current transformer 10 flows into the base of the Tr8 via a resistor 31 to make the Tr8 continuous. On the other hand, an FET 30 as well as a Tr9 operates similarly, however, a winding direction of the secondary winding 13 is reverse to that of the secondary winding 12 so that polarity of a generated current becomes reverse. Accordingly, the bipolar transistors Tr8, Tr9 are on/off operated alternately and a switching period thereof depends on a period of an output current pulse of the oscillation circuit 22.

Title: Charge pump circuit
Inventor: SOTOKARI HISASHI
IPC: H03K4/50
Filed: 1990-09-26
Abstract: PURPOSE:To accurately control the charging and discharging of a capacitor by providing a constant-current circuit whose current can be changed by means of an external resistor on the electronic circuit of a charge pump circuit provided with the electronic circuit between an input terminal and output terminal. CONSTITUTION:When a capacitor C is charged with electric charges, a 3rd constant-current circuit composed of a transistor Q6 and diode D4 charges the capacitor C. When the electric charges of the capacitor C are discharged, the discharge is performed by means of the constant current I0 of a 4th constant- current circuit composed of a diode D3 and transistor Q7. The charging/ discharging time of the capacitor C is decided by the capacitance value of the capacitor C and the charging/discharging current value I0 and, even when the part A surrounded by the dotted line is constituted of an integrated circuit, the constant current I0 can be changed by means of a variable resistor RL. Therefore, the charging/discharging time can be easily controlled without changing the capacitance of the capacitor C constituting a filter circuit together with a next-stage circuit E.

Title: Image forming device
Inventor: SAKURAI YOKO
IPC: G03G15/00
Filed: 1990-09-26
Abstract: PURPOSE:To execute the control of image forming in such a set state that an operation is easily performed by each operator by inputting the selection data of a fine item and previously making the setting at the time of a cover forming mode optional. CONSTITUTION:The data inputted by a data input means for inputting the data which selects the fine item of processing in a mode is stored in a storage means 410. When the instruction of the cover forming mode is inputted, the control of the image forming is executed by selecting the processing of the fine item, which is specified by the data in the storage means 410, by a control means 400. That means, by the input of the selection data of the fine item, the setting at the time of the cover forming mode can be previously made optional. Thus, by allowing each operator to previously input the data for setting the state where the operation is easily performed by him, the control of the image forming is executed in the set state that the operation is easily performed by him. Besides, the mistake of copying is reduced.
