IPC: G03D13/00
Filed: 1987-04-09
Abstract: PURPOSE:To stabilize picture quality by segmenting an exposure part by means of a casing, and controlling temperature in a casing chamber. CONSTITUTION:After a photosensitive material 14 in a magazine 12 is pulled out of its outer periphery and is cut in prescribed length by a cutter 58, it is wound on the outer periphery of an exposure drum 16 in the casing 500. After an exposure head 18 on the outer periphery exposes, the exposure drum 16 reversely rotates. The photosensitive material 14 is peeled off by a scraper, and transmitted to a heat development and transfer part 22 through an image forming solvent coating part 20. At that time, the casing 500 houses the rotating drum 16 and its peripheral parts. A ventilation fan, for instance, is provided at an appropriate plate in the casing 500, and a temperature sensor provided on the exposure head 18, for instance, detects temperature in the casing. According to the temperature detection signal, the ventilation fan is turned on or off to control the temperature. Thus a stable and satisfactory image can be always obtained.

Title: Hot water supplying apparatus
Inventor: ASANO MASAAKI
IPC: F23N5/14
Filed: 1994-03-30
Abstract: PURPOSE:To eliminate continuation of a state in which supply hot water exceeds a set supply hot water temperature due to a trouble of a mixing regulator. CONSTITUTION:A hot water supplying apparatus sets a time of starting counting of a combustion ON time in an ON and OFF cycle combustion operation to the time of detecting a flame by a flame detector after an actual combustion starting time. An excess heat quantity due to combustion heat quantity generated from the actual combustion start to a flame detection by the detector is previously obtained by an experiment, and stored in a controller 30. When a mixing regulator 14 is troubled, a time obtained by subtracting an ON time corresponding to the excess heat quantity from the combustion ON time calculated by a necessary combustion neat quantity is used as the combustion ON time in the case of calculating the combustion ON time by the controller 30.

Title: Multi-stage iil circuit
Inventor: MINAMIBATA SHIGEAKI
IPC: H01L27/08
Filed: 1985-04-24
Abstract: PURPOSE:To reduce the power consumption with a multi-stage structure by using a forward IIL which applies a pnp bipolar transistor TR to an injector and a reverse bipolar TR which applies an npn bipolar TR to an injector. CONSTITUTION:When the signal is transmitted to an upper stage from a lower stage, an npn bipolar TR Q2 of a cIIL at a lower stage is turned on and off. Thus, the npn bipolar TR Q2 at an upper stage is turned on and off. Then, the signal is transmitted to the upper stage from the lower stage. In the same way, a pnp bipolar TR Q4 of an iIIL at an upper stage and then the TR Q4 of an iIIL at a lower stage are turned on and off respectively when the signal is transmitted to an upper stage from a lower stage. Thus, the signals can be transferred freely between upper and lower stages. This can reduce the power consumption with a multi-stage structure and also increases the degree of freedom for circuit designing.

Title: Negative pressure piping for brake booster
Inventor: KANAIKE KAZUTOSHI
IPC: B60T17/04
Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To provide negative pressure piping for a brake booster by which a fluctuation of an engine speed can become smaller at the time of idling. SOLUTION: A restrictor 20 is interposed in a booster side piping part 41, and a sub-chamber 21 is interposed in a valve-to-restrictor piping part 41a. When an air flows out from a brake booster 1, the flow of the air is restricted by the restrictor 20 and an air flow per unit time decreases, and a fluctuation of an idling engine speed of an engine 2 can thereby become smaller. Since the sub-chamber 21 smoothens a pressure change by the air from the brake booster 1 to gradually elevate a pressure Pc on a valve-to-restrictor piping downstream part 41b, a sudden change of a front and a rear pressures of a one-way valve 5 is prevented and an operation of the one-way valve 5 can be thereby stabilized. The sub-chamber 21 also works as a negative pressure tank and can stably supply negative pressure to a first and a second chambers 9, 10.

Abstract: PURPOSE:To make a touch alarm unit possible to exert alarm before a protected object is broken by providing the unit with an alarm grid and a capacity change detecting section so that the touch alarm unit can detect the change in electrostatic capacity of the alarm grid to issue alarm. CONSTITUTION:Alarm grid 10 with conductive material printed over the entire surface of insulating plate 12 is attached to the outer surface of cabinet 1 so that conductive thin film 11 becomes an outer surface, and the conductive thin film 11 is insulated from the housing 1. Further, lead 13 is bonded to the conductive thin film 11, is extended into the inside of the housing 1, and is connected to a capacity change detecting section 14. Furthermore, when a hand touches the surface of alarm grid 10, capacity C1 that a human has is added to the alarm grid 10 to increase the electrostatic capacity of the alarm grid 10, whereby electron with which capacitor CO is charged moves to capacitor C1, whereby voltage at the capacity change detecting section 14 drops instantaneously, and whereby the capacity change detecting section 14 is charged by a time constant determined by resistor R and C0+C1 to obtain voltage V. This voltage is detected by the capacity detecting circuit 15 of the capacity change detecting section 14 to output an alarm signal and to activate a monitor to issue alarm, thereby informing a man in charge of security of the occurrence of a malicious thing.
