Patent JP-S57127306-A (JP)
Title: Phase comparator
Inventor: KUSAKABE HIROMI
IPC: H03D13/00
Filed: 1981-01-30
Abstract: PURPOSE:To reduce the output offset, by setting a phase comparing part to a B- or AB-class operation to reduce the bias current while no signal is delivered as well as to reduce the peak current of the input signal. CONSTITUTION:Each working current of transistors (TR)Q17 and Q18 in current mirror circuits CM1 and CM2 which serve also as differential amplifiers of a  phase comparing part 12 operates an AB- or B-class operation in which the peak current on the input signal supplied from an input signal source for phase to be  compared is reduced by a bias part 11. As a result, the mean value of an output current is set at zero through an LPF in case when the frequency of a switching signal is higher than the frequency of the input signal for phase to be compared. Thus the unbalance of a current mirror circuit CM3 comprising TRS Q23 and Q24 emerges int the form of an unbalance component of an output current waveform to be  changed into a waveform having the upper and lower parts asymmetric to each  other. This error component is turned into an output offset. In this case, a large  DC current does not flow due to the AB- or B-class operation, and accordingly  the output offset can be reduced by a degree equivalent to the DC current.

Title: Height controlling receiving device
Inventor: NAKAGAWA TAKAO
IPC: G01C5/00
Filed: 1998-01-27
Abstract: PROBLEM TO BE SOLVED: To make the position of an incident light easily confirmable by a worker by setting the light transmitting direction of a light emission type display mechanism indicating the incident position in the vertical direction of a reference light to be downward from the horizontal direction. SOLUTION: This height controlling receiving device is constituted in such a manner that the height of a ground working device based on a reference light is measured by receiving the reference light transmitted horizontally from a transmitter. The transmitting direction of the light of a light emission type display mechanism C for indicating the incident position in the vertical direction of the reference light is set downward from the horizontal direction. Namely, an LED 46 is arranged in each transparent window part 41B, and the attitude of the LED 46 is set so as to transmit the light from the LED 46 downward.  Thus, when the incident position of a laser beam to a level sensor is confirmed, a worker can recognize a bright light only by turning the line of sight from the position of a driver's seat to the display mechanism C, and grasp the incident position of the laser beam even in the daytime.

Title: Contact filter medium for biological treatment
Inventor: MATSUYAMA HIDETOSHI
IPC: C02F3/28
Filed: 1985-01-29
Abstract: PURPOSE:To obtain the title contact filter medium applicable to anaerobic biological treatment which is hardly put to practical use heretofore by providing fine protrusions on the surface of the contact filter medium which is applied to the biological membrane method at specified intervals in the biological treatment of org. sewage. CONSTITUTION:In the biological treatment of org. sewage, fine protrusions 4 are provided on the surface of a contact filter medium 1 at intervals of 3-20mu, and the filter medium is forced into a hollow four-footed body 5 having plural holes 6. When sewage is passed through the surface of the filter medium, both aerobes and anaerobes are collected by the protrusion 4 protruding from the surface of the filter medium and having 3-20mu height. Since the filter medium main body is a hollow four-footed body, the flow resistance is reduced, and more microbes are deposited on the surface per unit area. Consequently, the period of time from the starting to the normal operation can be shortened, stabilized purification can be maintained, the reaction rate is increased and the filter bed is hardly clogged.
