Patent JP-H02141731-A (JP)
Title: Automatic exposure controller
Inventor: HONMA HIDEO
IPC: H04N5/243
Filed: 1988-11-24
Abstract: PURPOSE:To perform appropriate exposure to various object patterns by deciding a luminance pattern at the time when the position of a detected area is changed on a screen, setting a photometric area at a position fitted for the luminance pattern and performing the control of exposure. CONSTITUTION:A signal level detection circuit 113 detects the mean value of signal levels on the inside and outside of detection frame 202 and the detected value is transmitted to a microcomputer 115, which detects a photometric mode and decides the position of a photometric frame based on the data. The detection frame 202 is subjected to wobbling up and down on the entire screen 201 based on a detection frame signal 110. The microcomputer 115 detects the luminance pattern and performs the decision of the photometric mode (to decide what position in the screen the photometric frame is set) and calculates appropriate exposure correction quantity from the signal levels on the inside/ outside of the detection frame. An exposure correction circuit 401 performs the control of exposure through an exposure correction signal 402 according to the calculated quantity. Thus, the appropriate control of exposure corresponding to the various object patterns is accomplished.

Title: Reproducing system for rotary head type tape recorder
Inventor: TOKUMATSU HIROSHI
IPC: G11B5/09
Filed: 1987-11-20
Abstract: PURPOSE:To equalize the characteristic of a reproducing system to that of the standard mode by changing the tape running speed and the cylinder rotational frequency to n-fold those of an option recording/reproducing mode and intermittently driving motors to reproduce signals. CONSTITUTION:A cylinder servo circuit 5, a capstan servo circuit 6, and a reel servo circuit 7 are controlled by a control circuit 2 through independent control lines 21-23. A cylinder motor 16 is rotated at an n-fold speed of the option mode, and a capstan motor 17 and reel motors 18 and 19 are so intermittently driven that they are stopped for (1-1/n) after being driven for 1/n, and they are rotated during driving for 1/n to run and wind the tape at the n-fold speed of the option mode. Consequently, the reproduced signal frequency is equal to that of the standard mode when the tape recorded in the option mode is reproduced with two-fold tape running speed and cylinder rotational frequency. Thus, an electromagnetic conversion system and the reproducing system consisting of an equalizer, an ATF, etc., are operated with the same characteristics as the standard mode.

Title: Moisture detector
Inventor: AKIYAMA JUNICHI
IPC: G01N27/12
Filed: 1997-10-13
Abstract: PROBLEM TO BE SOLVED: To provide a moisture detector that is simple in configuration and at the same time can be adjusted easily. SOLUTION: Analog-vaue moisture output from a moisture sensor is converted into a digital value (S13), the moisture output is corrected based on a correction value being set to a potentiometer (S18), and a data table is searched and a moisture value is searched (S20). Then, the searched value is converted into a PWM signal (S22) and then is converted into an analog voltage value by a moisture output smoothing circuit. In this manner, since a moisture sensor value that changes logarithmically is processed digitally, an adjustment for coping with logarithmic characteristics is not required. Also, since the data table is used, it is not necessary to perform a complex arithmetic processing.

Title: Device for accelerating start of diesel engine
Inventor: HATAMURA KOICHI
IPC: F02B3/06
Filed: 1986-12-11
Abstract: PURPOSE:To prevent exhaust fumes from being introduced into a combustion chamber and to raise temperature during an early stage or compression stroke by throttling an intake passage during the start or warmup running stages and supplying air from an upstream side of the throttle valve to a combustion chamber during a period from the last stage of the intake stroke to the early stage of the compression stroke. CONSTITUTION:While a throttle valve 10 is arranged in a main intake passage 4a of an intake passage 4, an on-off valve 20 is arranged at an opening connecting a bypass 4b which bypasses the throttle valve 10 to the main intake passage 4a. While the throttle valve 10 is throttle during the start or warmup running stages, the on-off valve 20 is opened to supply a large amount of air from an upstream side of the throttle valve 10 to a combustion chamber 3 during a period from the last stage of the intake stroke to the early stage of the compression stroke. Since this prevents exhaust fumes from being introduced into the combustion chamber, temperatures can be raised during an early stage of the compression stroke as well as preventing wear of the inner sliding surface of a cylinder due to carbon.
