Title: Thickness measuring device
Inventor: UEIN BUI SORIN
IPC: G01B11/06
Filed: 1995-08-29
Abstract: PROBLEM TO BE SOLVED: To arrange an interferometer at a position distant from a film to be measured, by transmitting light from a light source to the film at the distant position with the use of an optical fiber so as to converge the reflected light thereof. SOLUTION: Light from a low coherent light source 12 composed of an edge emission type LEDs, is transmitted through an optical fiber 14, and is focused onto a film 13 to be measured with the use of a lens 15 so as to from an image. Further, a part of reflected light therefrom to be returned to the optical fiber 14 is converged by a lens 15, and is fed to a Michelson interferometer 18 through a directive couple 16 and an optical fiber 17. In the interferometer 18, incident light is split by a beam splitter 19 into paths to a stationary mirror 20 and a movable mirror 21, and the reflected light is recombined in the splitter 19 and is then transmitted to a photodiode 22 for measuring a light intensity which is varies in accordance with a position of the mirror due to light interference. With this arrangement, the interferometer 18 for measuring a thickness of a film on moving is located at a position distant from a manufacturing atmosphere where the interferometer 18 is easily soiled.

Title: Facsimile equipment having automatic answering telephone recording function
Inventor: SUGIYAMA NORIO
IPC: G06F12/16
Filed: 1997-08-28
Abstract: PROBLEM TO BE SOLVED: To notice who records an automatic answering telephone and also where substitutional receiving is performed by re-preserving information which is stored in a memory that does not perform battery backup to a memory which performs battery back up when a main power supply is off. SOLUTION: When a main power supply 18a of facsimile equipment is turned off due to service interruption and being off of a main power supply plug socket, it is confirmed whether voltage value of capacitive auxiliary power supply falls <= a fixed value (threshold). When the voltage value of the auxiliary power supply falls <= the threshold, it is confirmed whether information preserved in a volatile RAM 9 exists. If information is not preserved in the RAM 9, various functions such as an automatic answering telephone recording function are stopped and information preservation processing is finished. On the other hand, if information is stored in the RAM 9, management information such as the number of the other party and a telephone receiving time is preserved in a nonvolatile RAM 11, various functions are stopped and information preservation processing is finished.

Title: Manufacture of semiconductor device
Inventor: MASUOKA SADAAKI
IPC: H01L21/336
Filed: 1998-08-31
Abstract: PROBLEM TO BE SOLVED: To suppress variations of the threshold voltage of a semiconductor device even when the gate length of the device varies in a short-channel area, by obliquely performing the counter dope injection of a channel by using a dummy gate as a mask from two directions in the direction of the gate length. SOLUTION: In a semiconductor device, As+ 202 is obliquely injected at an injecting angle 204 of 45 deg. from two directions in the direction of the gate length of the device. When the gate length is 0.16 μm 201, any counter dope layer having a low channel concentration is no formed, but, when the gate length is 0.18 μm in the dammy gate 211, counter dope layers 215 having low channel concentrations are formed in 0.02 μm parts on both sides of a gate end. When the gate length is 0.20 μm in the dammy gate 221, in addition, counter cope layers 225 having low channel concentrations are formed in 0.04 μm portions on both sides of the gate end. Namely, the threshold voltage Vth of the semiconductor device drops due to such an effect that the proportion of the occupying area of the counter dope layers having low channel concentrations in the whole channel increases as the gate length becomes longer.

Title: Electrophotographic printer
Inventor: TAKAHASHI ZENJI
IPC: G03G15/00
Filed: 1990-09-18
Abstract: PURPOSE:To suppress the wear and deterioration of a photosensitive drum by decreasing the rotating speed of the photosensitive drum by a motor which is variable in rotating speed until the feeding of a form is instructed after a printing process. CONSTITUTION:A microprocessor 21' once receiving a form hopping instruction drives the motor 29 at a high speed to rotate the rotary driving part for the photosensitive drum 14, a cleaner 24, a developing unit 17, and a fixation unit 19. After the printing process, the frequency select signal (f) of a frequency converting circuit 29 is varied to a low-speed rotation selection side and the frequency of a motor control clock (g) is decreased to allow the motor 29 to rotate at the low speed. Thus, the rotating speed of the photosensitive drum is decreased until a printing form is fed after the printing process to suppress the wear and deterioration of the photosensitive drum without lowering the printing throughput.

Inventor: JOHN CLIFFORD JONES
IPC: G02F1/133
Filed: 1998-08-31
Abstract: PROBLEM TO BE SOLVED: To provide an apparent difference between a pixel selection state and a non-selection state. SOLUTION: A strobe signal is applied to one of plural 1st electroses so as to address pixels of a liquid crystal device by a strobe signal and a data signal and a data signal is applied to one of plural 2nd electrodes. The data signal includes a selection data signal and a non-selection data signal each of which has one period and an identification(ID) part shorter than the period. The ID part of the selection data signal is different from that of the non- selection data signal. Selective synthetic signals A, B almost coincident with an ideal waveform for a quick state change are applied to pixels and non- selective synthetic signals C, D for giving an apparent difference between two states are also applied. The strobe signal includes a 1st part to be applied simultaneously with the ID part of the data signal and a 2nd part to be applied after the ID part of the data signal.  Since a high voltage part is included in the 2nd part, improved performance and address speed can be obtained.

Title: Main memory data transfer control system
Inventor: FUKUDA MASAHARU
IPC: G06F13/18
Filed: 1989-09-25
Abstract: PURPOSE:To increase the data transfer speed by starting the bus acquiring operation for a second bus by a bus interface mechanism before reception of main memory read data in accordance with a previous report signal. CONSTITUTION:Before read data to be transferred to a used device connected to a second bus 30 is outputted from a main memory device 10 to a first bus 20, the previous report signal to notify the output of read data beforehand is outputted from the main memory device 10 to the first bus 20. In response to the previous report signal on the first bus 20, a bus interface mechanism 40 starts the bus acquiring operation to acquire the second bus 30 which is used to transfer read data, which is outputted from the main memory device 10 to the first bus 20 thereafter, to a transfer destination used device. Thus, the start time of the bus acquiring operation is quickened in comparison with the conventional system where the bus acquiring operation of the second bus is started after output of read data from the main memory device to the first bus, and the overhead is reduced.

Abstract: PURPOSE:To decrease the antenna element length only with the addition of a simple circuit by connecting a capacitor having a required capacitance between a lower end of a negative pole element and an outer conductor of a coaxial feeder leading to a feeding part in parallel with said element. CONSTITUTION:In taking the length of the line as l1<lambda/4 for example, the impedance Zs in an inductance L ( reactance jX1).
