Title: Information display device
Inventor: ANDO MASANOBU
IPC: G02F1/1335
Filed: 1990-02-26
Abstract: PURPOSE:To simplify the structure of a device itself and to eliminate the need of the occupied space of a floor surface where the device is set by using an existent fluorescent lamp for illumination as a light source for display element unit and attaching an information display appliance on a ceiling. CONSTITUTION:When designation concerning the display of information is transmitted to the information display appliance 30, desired information is displayed on the display element unit 32 to which power is supplied from a power source unit 33. In such a case, visibility on the display screen of the unit 32 is low, so that it is made high by illuminating the unit 30 from a back side by the fluorescent lamp for illuminating 20. Since the fluorescent lamp 20 and the unit 33 considerably radiate heat, the radiated heat is forcibly exhausted to the outside of the display appliance 30 from an air vent 34 by a fan 35. Then, the information displayed on the display appliance 30 is directly viewed by a user who looks up to the ceiling 10. Thus, the structure of the device itself is simplified and the occupied space of the floor surface where the device is set is not necessitated.

Title: Cylindrical capacitor formation method
Inventor: KOSHIDAKA TOSHIAKI
IPC: H01L21/02
Filed: 1999-02-23
Abstract: PROBLEM TO BE SOLVED: To accurately form a capacitor lower electrode and to manufacture a cylindrical capacitor with a simple process by treating a semiconductor substrate with a chemical liquid for causing solubility to decrease due to the reaction with photo resist before applying the photo resist and allowing the photo resist to remain only in a hole. SOLUTION: Before applying a positive-type photo resist 4, a semiconductor substrate 1 is treated by a chemical liquid for reducing solubility for the development liquid of the positive-type photo resist 4 in reaction with the positive-type photo resist 4. In this case, the concentration inside a hole 2 with a wide surface area is made higher than that on the surface of the semiconductor substrate 1, thus allowing the positive-type photo resist 4 in the hole 2 that becomes a capacitor to remain and excluding the positive-type photo resist 4 on the surface of the semiconductor substrate 1 after the exposure and development of an entire surface and hence accurately forming the lower electrode of a capacitor and manufacturing a cylindrical capacitor with a simple process.

Title: Frequency synthesizer
Inventor: SAGAWA MORIKAZU
IPC: H03L7/187
Filed: 1984-03-09
Abstract: PURPOSE:To attain stable operation over a wide band even at a high frequency region and also to decrease power consumption by adopting the PLL circuit constitution where outputs of an analog frequency divider and of a loop filter are connected to a control terminal of a frequency divider. CONSTITUTION:A feedback circuit of the analog frequency divider 20 includes a capacitor 35 and a varactor diode 32 and the capacitance is controlled by an output of a loop filter 12. Since the frequency divider 20 takes charges of a high speed operation, a prescaler 21 saves a frequency divider operated at a high speed and having a large power consumption and then the power consumption is decreased. The capacitance value of the diode 32 is changed in response to an output voltage of the loop filter 12 applied to a control circuit 34 in the frequency divider circuit 20 and the capacitance of the feedback circuit is changed. Then the frequency divider band is widened by changing the capacitance of the feedback circuit to be small when the input frequency is high and large when the frequency is low. Thus, broad band and low power consumption are realized by applying an output voltage of the filter 12 to the feedback circuit constituted in this way.
