Title: Exposure controller for copying machine
Inventor: HORIGUCHI MASASHI
IPC: G03B27/72
Filed: 1988-09-28
Abstract: PURPOSE:To extremely easily control exposure with high accuracy by changing the duty cycle of pulses impressed on an electronic shutter so that exposure may be adjusted. CONSTITUTION:At the time of exposing a photosensitive material 11 through a slit, a PLZT 17 is arranged as the electronic shutter at the position of a pupil and light transmitting state and a light shielding state are repeated in the specified duty cycle, so that the reflected light from a reflecting original 1 is converted into light by pulse. The light by pulse which passes through the PLZT 17 is made incident on the photosensitive material 11 which moves along the image-formation surface of a lens, so that the image recorded on the reflecting original 1 is recorded on the photosensitive material 11. Since the duty cycle of intermittent exposure is adjusted at the time of copying thus, the change of gradation based on the intermittent exposure is not caused and the exposure of the photosensitive material 11 is adjusted according to the recording density of the reflecting original 1.

Title: Ventilating device for air conditioner
Inventor: NAKAO KEIJI
IPC: F04D17/04
Filed: 1987-09-28
Abstract: PURPOSE:To reduce high frequency noise without decreasing air quantity by forming a casing of a cross-flow fan with each opposed surface in front and in the rear, while forming a clearance between a fan blade and the front opposed surface to be larger at both ends but smaller at the central part respectively. CONSTITUTION:An air conditioner body 10 is provided with a heat exchanger 11, a crossfow fan 12 and a fan motor 13. Each of front and rear opposed surface 14, 15 is set up in this fan 12, whereby a casing 16 is formed. By the above constitution, a clearance (t) between a blade 17 of the fan 12 and the front opposed surface 14 is varied in the axial direction. Namely, this clearance (t) is made larger at both ends of the fan 12, whereby a high frequency noise due to interference with the blade 17 is reduced. A the central part where flow velocity is rapid and air capacity is much, the clearance (t) is made smaller, preventing any drop in performance from occurring. The high freuqncy noise is thus reduced without entailing decrease in the air capacity.

Title: Exhaust gas purifying catalyst and its production
Inventor: TERADA KAZUHIDE
IPC: B01J23/40
Filed: 1993-09-29
Abstract: PURPOSE:To more efficiently purge NOx in a wide exhaust gas temp. range by forming alumina of a mixed-phase alumina with the alpha-conversion rate specified. CONSTITUTION:This exhaust gas purifying catalyst consists of alumina and a catalytic metal depositing on the alumina. The catalytic component is at least one kind selected from platinum-group metals, the alumina is formed of the mixed-phase alumina having theta and alpha phases and with the alpha-conversion rate R controlled to 0.5<=R<=95%. The mixed-phase alumina is obtained by heat-treating activated alumina at 800-1100 deg.C to cause change of phase. When the catalytic metal is deposited on the mixed-phase alumina, the dispersibility of the metal is suppressed as compared with the activated alumina, and the catalyst oxidizes HC weakly. Thus, HC is partially oxidized to form active CHO in a wide exhaust gas temp. range, NOx are reduced and purged by the active CHO, and the purification temp. range is widened.

Filed: 1987-09-28
Abstract: PURPOSE:To process a keyboard slow in response speed with a CPU fast in processing speed by providing a delaying signal generating means to continue to impress a signal to delay the fetching time of the data to the CPU for a constant time when the CPU accesses a key scanning circuit. CONSTITUTION:By a keyboard selecting signal KS outputted by a CPU 5, a memory ready signal generating circuit 6 starts an action and the signal given to a memory ready signal receiving port MR is set from an H level to an L level. While a memory ready signal is an L level, the fetching period of the data of a keyboard 2 is postponed. During the period, the signal of the keyboard 2 gradually rises and the data are fetched into the CPU 5. Thereafter, the memory ready signal generating circuit 6 returns a signal given to the memory ready signal receiving port MR from the L level to the H level and the CPU 5 returns to a normal processing speed.

Filed: 1987-09-30
Abstract: PURPOSE:To enable appropriate driving of a carriage to be achieved even where a motor with a small torque is used, by detecting the temperature of a lubricant, controlling a carriage- driving motor according to the result of the detection, and regulating the acceleration at the time of accelerating or decelerating a carriage. CONSTITUTION:A guide shaft 4 is provided with a thermistor 9 for detecting the temperature of the shaft 4 to thereby detect the temperature of a lubricant applied to the shaft 4. The temperature of the guide shaft 4 is detected by the thermistor 9, thereby indirectly detecting the temperature of the lubricant applied to the shaft 4, and the acceleration at the time of accelerating a carriage 6 from a stopped state to a constant-speed movement and the deceleration at the time of decelerating the carriage 6 from the constant-speed movement to the stopped state are regulated according to the result of the detection. Namely, when the temperature of the lubricant is low so that the frictional loads between the carriage 6 and the guide shaft 4 and between the carriage 6 and a guide rail 5 are high and a load on a stepping motor 10 is high, the moving amounts of the carriage 6 at the times of acceleration and deceleration are set to be large, thereby reducing the absolute values of the accelerations. When the temperature of the lubricant is high and the load on the motor 10 is low, the moving amounts at the times of acceleration and deceleration are set to be small, thereby enlarging the absolute values of the accelerations.

Title: Keyboard input device
Inventor: HASHIBA ICHIRO
IPC: G06F3/02
Filed: 1988-09-28
Abstract: PURPOSE:To prevent the load applied to a host computer even in a different Roman character/KANA (Japanese syllabary) conversion system by adding a Roman character key to a keyboard to identify the input of Roman characters. CONSTITUTION:When an operator inputs a certain type of data through a keyboard 1, and a Roman character key part 5 is pushed, the input Roman characters are converted into KANA characters by a microcontroller 2. Then the microcontroller 2 sends a prescribed signal to a host computer. While the normal data supplied from the keyboard 1 is sent to the host computer as it is in case the part 5 is not pushed. In case the operator performs the input that cannot be recognized as the Roman characters at operation of the keyboard 1, the microcontroller 2 decides the wrong input of Roman characters and actuates a buzzer 3 to inform the operator of the input mistake.

Abstract: PURPOSE:To eliminate cumbersome manipulation at the time of making a phone call by providing a generation means of selection signal, a specified area code storing means, a in-memory-means information judging means, and a calling means, and adding an identification signal to a selection signal in case the area code included in the selection signal coincides with a specified area code, then calling. CONSTITUTION:If a selection signal inputted from a serial/parallel (S/P) converter 3, a CPU 4 temporalily stores the selection signal in a RAM 6, and judges if a selection switch 10 is in the NTT-side. In case said switch is connected to an electrical communi cation service corporation other than the NTT, the CPU 4 judges if the area code included in the stored selection signal in the RAM 6 is such one as dealt with by said corporation or not, based on the information in the selection information storing area and the area code storing area in a ROM 5. If so, a corresponding identification signal in the ROM 5 is taken out, and the signal is inputted to a parallel/serial (P/S) converter 7 together with the selection signal stored in the RAM 6. As a result, to make a telephone call, what is necessary for a user is just to dial the subscriber's telephone number of the opposite.
